Conformance to EC Directives

The CV-series PCs that comply with EC Directives must be installed as follows:

1, 2, 3...

1. The CV-series PCs are designed for installation inside control panels. The

PC must be installed within a control panel.

2. Use reinforced insulation or double insulation for the DC power supplies to

be connected to the DC I/O Units for CV500-PS211. Use separate power

supplies as the external power supplies for the Relay Output Units and the

power supplies for the DC I/O Units.

3. To meet the EC Directives (Low Voltage Directive), the maximum switching

capacity while the CV500-PS211 is being operated is 24 VDC/2 A.

xiv

Conformance to EC Directives

4. PCs complying with EC Directives also conform to the Common Emission

Standard (EN50081-2). When a PC is built into a machine, however, noise

can be generated by switching devices using relay outputs and cause the

overall machine to fail to meet the Standards. If this occurs, surge killers

must be connected or other measures taken external to the PC.

The following methods represent typical methods for reducing noise, and

may not be sufficient in all cases. Required countermeasures will vary

depending on the devices connected to the control panel, wiring, the config

-

uration of the system, and other conditions.

Countermeasures

Refer to EN50081-2 for more details.

Countermeasures are not required if the frequency of load switching for the

whole system including the PC is less than 5 times per minute.

Countermeasures are required if the frequency of load switching for the whole

system including the PC is 5 or more times per minute.

The Role of the PC

Section 1-2

1-1 Control Systems

A

Control System is the electronic equipment needed to control a particular pro-

cess. It may include everything from a process control computer, to the factory

computer, down through the PCs, and then on down through the network to the

I/O devices: control components like the switches, stepping motors, solenoids,

and sensors which monitor and control mechanical operations.

Process Control Computer

Factory Computer

PCs

PC

I/O devices

A

Control System can involve very large applications where many different mod-

els of PC are networked together or it could be an application as small as a single

PC controlling a number of output devices.

1-2 The Role of the PC

The PC is the part of the Control System that directly controls the manufacturing

process. According to the program stored in its memory, the PC accepts data

from the input devices connected to it and uses this data to monitor the con-

trolled system. When the program calls for some action to take place, the PC

sends data to the output devices connected to it to cause that action to take

place. The PC may be used to control a simple, repetitive task, or it may be con

-

nected to other PCs or to a host computer in order to integrate the control of a

complex process.

2

The Role of the PC

Section 1-2

1-2-1 Input Devices

PCs can receive inputs from either automated or manual devices. The PC could

receive data from the user via a pushbutton switch, keyboard, or similar device.

Automated inputs could come from a variety of devices: micro-switches, timers,

encoders, photoelectric sensors, and so on. Some devices, like the limit switch

shown below, turn ON or OFF when the equipment actually makes contact with

them. Other devices, like the photoelectric sensor and proximity sensor shown

below, use other means, such as light or inductance, in order to get information

about the equipment being monitored.

Photoelectric Sensor

Proximity Sensor

Limit Switch

1-2-2 Output Devices

A

PC can output to a myriad of devices for use in automated control. Almost any

-

thing that you can think of could be controlled by a PC. Some of the most com

mon devices are motors, solenoids, servomotors, stepping motors, valves,

switches, indicator lights, buzzers, and alarms. Some of these output devices,

such as the motors, solenoids, servomotors, stepping motors, and valves, affect

the controlled system directly. Others, such as the indicator lights, buzzers, and

alarms, provide outputs to notify personnel operating or monitoring the system.

Solenoid

PC Operation

Section 1-3

1-3 PC Operation

PCs operate by monitoring input signals and providing output signals. When

changes are detected in input signals, the PC reacts through the user-pro-

grammed internal logic to produce output signals. The PC continually executes

the program in its memory to achieve this control.

CPU

Programming

Device

A program for your applications must be designed and stored in the PC. This

program is then executed as part of the cycle of internal operations of the PC.

Execution Cycle

When a PC operates, i.e., when it executes its program to control an external

system,

a series of operations are performed inside the PC. These internal oper-

ations can be broadly classified into the following four categories. Refer to the

CV-series PCs Operation Manual: Ladder Diagrams for details.

1, 2, 3...

1. Common (or overseeing) processes, such as watchdog timer operation and

testing the program memory.

2. Data input and output.

3. Program execution.

4. Peripheral device servicing.

Cycle Time

The total time required for a PC to perform all these internal operations is called

the cycle time.

Timing is one of the most important factors in designing a Control System. For

accurate operations, it is necessary to have answers to such questions as these:

• How long does it take for the PC to execute all the instructions in its memory?

• How long does it take for the PC to produce a control output in response to a

given input signal?

4

CV-series Manuals

Section 1-4

The cycle time of the PC can be automatically calculated and monitored, but it is

necessary to have an understanding of the timing relationships within the PC for

effective System design and programming. Refer to the CV-series PCs Opera

-

tion Manual: Ladder Diagrams for details on internal PC processing and to the

CVSS Operation Manuals for details on monitoring the cycle time.

1-6 Networks and Remote I/O Systems

Systems that can be used to create networks and enable remote I/O are intro

-

duced in this section. Refer to the operation manuals for the Systems for details.

SYSMAC NET Link System

The SYSMAC NET Link System is a LAN (local area network) for use in factory

automation systems. The SYSMAC NET Link System can consist of up to 128

nodes among which communications may be accomplished via datagrams,

data transfers, or automatic data links.

Datagrams transmit and receive data using a command/response format. Com

-

mands can be issued from the user program by the DELIVER COMMAND in-

struction (CMND(194)).

Data can also be transmitted and received using the NETWORK SEND and

NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user pro-

gram. Up to 256 words of data can be transferred for each instruction.

Automatic data links allow PCs and computers to create common data areas.

Networks and Remote I/O Systems

Section 1-6

SYSMAC LINK System

Networks can also be created using SYSMAC LINK Systems. A SYSMAC LINK

System can consist of up to 62 PCs, including the CV500, CV1000, CV2000,

CVM1, C200H, C1000H, and C2000H. Communications between the PCs is ac

complished via datagrams, data transfers, or automatic data links in ways simi

lar to the SYSMAC NET Link System.

-

The main differences between SYSMAC NET Link and SYSMAC LINK Systems

is in the structure of automatic data links and in the system configuration, e.g.,

only PCs can be linked in SYSMAC LINK Systems, whereas other devices can

form nodes in SYSMAC NET Link Systems.

Datagrams transmit and receive data using a command/response format. Com

-

mands can be issued from the user program by the DELIVER COMMAND in-

struction (CMND(194)).

Data can also be transmitted and received using the NETWORK SEND and

NETWORK RECEIVE (SEND(192)/RECV(193)) instructions in the user pro-

gram. Up to 256 words of data can be transferred for each instruction.

Automatic data links allow PCs and computers to create common data areas.

Personal Computer Unit

The Personal Computer Unit is a full-fledged IBM PC/AT compatible that can be

used to run independent programming directly on a Rack to eliminate the need

for separate installation space. It can run along or connected to any of the normal

peripherals supported by IBM PC/AT compatibles (mice, keyboards, monitors,

data storage devices, etc.), and as a CPU Bus Unit, the Personal Computer Unit

interfaces directly to the PC’s CPU though the CPU bus to eliminate the need for

special interface hardware, protocols, or programming.

1-9 Improved Specifications

1-9-1 Upgraded Specifications

The following improvements are applicable to all CV500-CPU01-E and

CV1000-CPU01-E CPUs with lot numbers in which the rightmost digit is 3

(jjj3) or higher.

1, 2, 3...

1. The MLPX(110) (4-TO-16 DECODER) instruction has been improved to

also function as a 8-to-256 decoder and the DMPX(111) (16-TO-4 ENCOD-

ER) instruction has been improved to also function as a 256-to-8 encoder

.

To enable this improvement, the digit designator (Di) has been changed as

shown below.

Digit number:

3 2 1 0

0

Specifies the first digit to be converted

4-to-16/16-to-4: 0 to 3

8-to-256/256-to-8: 0 or 1

Improved Specifications

Section 1-9

3. The operation of Completion Flags for timers has been changed so that the

Completion Flag for a timer turns ON only when the timer instruction is

executed with a PV of 0000 and not when the timer

value of 0000, as was previously done.

’s PV is refreshed to a PV

Only the timing of the activation of the Completion Flag has been changed,

and the timer s PV is still refreshed at the same times (i.e., when the timer

’

instruction is executed, at the end of user program execution, and every

80 ms if the cycle time exceeds 80 ms).

4. The READ(190) (I/O READ) and WRIT(191) (I/O WRITE) instructions have

been improved so that they can be used for Special I/O Units on Slave

Racks under the following conditions.

a) The lot number of the Remote I/O Master Unit and Remote I/O Slave Unit

must be the same as or latter than the following.

01

X

2

1992

October (Y: November; Z: December)

1st

b) The DIP switch on the Remote I/O Slave Unit must be set to “54MH.”

c) The Special I/O Unit must be one of the following: AD101, CT012,

CT021, CT041, ASC04, IDS01-V1, IDS02, IDS21, IDS22, or LDP01-V1.

(The NC221-E, NC222, CP131, and FZ001 cannot be mounted to Slave

Racks.)

1-9-2 Version-1 CPUs

CV-series CPUs were changed to version 1 from December 1993. The new

model numbers are as follows: CVM1-CPU01-EV1, CVM1-CPU11-EV1,

CV500-CPU-EV1, CV1000-CPU-EV1, and CV2000-CPU-EV1. (Of these, all

CVM1 CPUs were changed to version 2 from December 1994; refer to the next

sections for details.)

The following additions and improvements were made to create the version-1

CPUs.

PT Link Function

EEPROM Writes

The host link interface on the CPU can be used to connect directly to Program

-

mable erminals (PTs) to create high-speed data links. To use the PT links, turn

T

ON pin 3 of the DIP switch on the CPU. Pin 3 must be turned OFF for host link

connections.

With the new CPUs, you can write to EEPROM Memory Cards mounted to the

CPU by using the file write operation from a Peripheral Device. A Memory Card

Writer is no longer required for this write operation. Writing is possible in PRO

GRAM mode only.

-

New Command

Faster Host Links

Faster Searches

A new I/O REGISTER command (QQ) has been added so that words from differ-

ent data areas can be read at the same time.

The communications response time for the built-in host link interface on the CPU

has been improved by a factor of approximately 1.2.

The search speed from Peripheral Devices for instructions and operands has

been nearly doubled.

1-9-3 Version-2 CVM1 PCs

CVM1 CPUs were changed to version 2 and a new CPU was added from De-

cember 1994. The new model numbers are as follows: CVM1-CPU01-EV2,

CVM1-CPU11-EV2, and CVM1-CPU21-EV2.

13

Improved Specifications

Section 1-9

The following additions and improvements were made to create the version-2

CPUs.

CMP/CMPL

New versions of the CMP(020) and CMPL(021) have been added that are not

intermediate instructions. The new instructions are CMP(028) and CMPL(029)

and are programs as right-hand (final) instructions. A total of 24 other new com

-

parison instructions have also been added with symbol mnemonics (e.g., >, +,

and <).

XFER(040)

DMPX(111)

New Flags

This instruction has been upgraded so that source and destination areas can

overlap.

This instruction has been upgraded so that either the MSB or the LSB can be

specified for use as the end code. Previously only the the MSB could be used.

Underflow and Overflow Flags have been added at A50009 and A50010, re-

spectively. These flags can be turned ON or OFF when executing ADB, ADBL,

SBB, and SBBL and can be saved or loaded using CCL and CCS.

New Instructions

A total of 125 new instructions have been added. These instructions are sup-

ported by version-2 CPUs only.

Faster Online Editing

The time that operation is stopped for online editing has been reduced and is no

longer added to the cycle time. The following are just a couple of examples.

Edit

Time operation is stopped

Adding or deleting one instruction block at the

beginning of a 62K-word program

Approx. 0.5 s

Deleting an instruction block containing JME

from the beginning of a 62K-word program

Approx. 2.0 s

The above speed increase also applies to all V1 CPUs with lot numbers in which

the rightmost digit is 5 (jjj5) or higher.

New Host Link Commands

New C-mode commands for the CPU Host Interface have been added and the

functionality of existing commands has been improved as follows:

New Commands

• RL/WL: Read and write commands for the CIO Area.

• RH/WH: Read and write commands for the CIO Area.

• CR: Read command for the DM Area.

• R#/R$/R%: SV read commands.

• W#/W$/W%: SV change commands.

• *: Initialization command.

Improved Commands

• The Link Area (CIO 1000 to CIO 1063) and Holding Area (CIO 1200 to

CIO 1299) can now be specified for the KS, KR, KC, and QQ commands.

• CVM1-CPU21-EV2 can now be read for the MM command.

The above new and improved commands can also be used with all V1 CPUs

with lot numbers in which the rightmost digit is 5 (jjj5) or higher.

Note Only the following Programming Devices support version-2 CPUs: SSS

(C500-ZL3AT1-E) and the CVM1-PRS21-EV1 Programming Console

(CVM1-MP201-V1). Of these, the SSS does not support SFC and thus cannot

be used for the CV500, CV1000, and CV2000. Use the CVSS for these PCs.

System Configuration

Section 2-1

2-1 System Configuration

This section provides illustrations of CV-series PC Systems, which can be clas

-

sified into five different types of configuration.

• Systems with only a CPU Rack

• Systems with only CV-series Expansion I/O Racks.

• Systems with an Expansion CPU Rack.

• Systems with a Single CV-series Expansion I/O Rack.

• Systems with C500 Expansion I/O Racks.

If only a CPU Rack is used, an I/O Control Unit is not required, but the CPU Rack

is otherwise the same as those in the following examples. The specific Units

used in the configuration are described in more detail later.

The maximum I/O capacity with any configuration is 512 points (32 words) for

the CV500 or CVM1-CPU01-EV2; 1,024 points (64 words) for the CV1000 or

CVM1-CPU11-EV2; and 2,048 points (128 words) for the CV2000 or

CVM1-CPU21-EV2. The I/O capacity will be less depending on the Racks and

the types of Units mounted.

Systems with only

CV-series Expansion I/O

Racks

The following figure shows an assembled CV-series CPU Rack and seven Ex-

pansion I/O Racks. Up to seven Expansion I/O Racks may be connected in one

or two series from the CPU Rack. The total length of I/O Connecting Cable must

be 50 m or less for each series and a Termination Resistance Unit must be be

connected to the last Rack or to the unused I/O Control Unit connector.

Units can be mounted to any slot on the Racks shown for them below.

System Configuration

Section 2-1

Systems with an Expansion When nine or more CPU Bus Units (Temperature Controller Data Link Units,

CPU Rack

SYSMAC NET Link Units, SYSMAC LINK Units, SYSMAC BUS/2 Remote I/O

Master Units, Ethernet Units, BASIC Units, and Personal Computer Units) are

required in a System, the CPU Rack may be extended by connecting an Expan

-

sion CPU Rack to enable mounting up to 16 CPU Bus Units.

Only one Expansion CPU Rack may be connected to a CPU Rack. A system that

includes an Expansion CPU Rack can be extended by connecting up to six Ex

-

pansion I/O Racks. The Expansion I/O Racks may be connected in one or two

series from the CPU Rack. The total length of I/O Connecting Cable must be

50 m or less for each series and a Termination Resistance Unit must be con-

nected to the last Rack or to the unused I/O Control Unit connector.

Using an Expansion CPU Rack does not increase the maximum I/O capacity of

the PC; it only increases the number of CPU Bus Units that can be used.

Units can be mounted to any slot on the Racks shown for them below.

Racks

Section 2-2

2-2 Racks

This section describes the Racks used to construct a PC System. The individual

components used to construct the Racks are described in the next section.

2-2-1 CPU Racks

The following figure shows the parts of the CPU Rack. There are five Back-

planes available for the CPU Rack. Any CPU can be mounted to any Backplane.

The only differences in the Backplanes is the number of slots that they provide

for Units, their expansion capability, and the number of slots for CPU Bus Units.

The CV500-BC031, CV500-BC051, and CV500-BC101 provide complete ex-

pansion capability and provide 3, 5, and 10 slots, respectively, for Units other

than the CPU, Power Supply Unit, and I/O Control Unit.

The CVM1-BC053 and CVM1-BC103 do not support I/O Control Units and pro

-

vide 5 and 10 slots, respectively, for Units other than the CPU and Power Supply

Unit. Because I/O Control Units are not supported, these Backplanes can be

connected only to a single Expansion I/O Rack as illustrated on page 18.The

CPU Backplane cannot be used for an Expansion CPU or Expansion I/O Rack.

2-2-2 Expansion CPU Racks

An Expansion CPU Rack can be provided to increase the mounting space for

CPU Bus Units. The Expansion CPU Rack is connected directly to the CPU

Rack. Two cables are required to connect the Expansion CPU Rack to the CPU

Rack, a CPU Bus Cable and an I/O Connecting Cable. If either of these connec

-

tions is broken, the system will be disabled

Only one Expansion CPU Rack can be connected to the CPU Rack. T

o further

increase the number of I/O Units, a series of Expansion I/O Racks may be con

-

nected to the Expansion CPU Rack or to the I/O Control Unit on the CPU Rack. If

no Expansion I/O Rack is connected to the I/O Interface Unit, connect a Termina-

tion Resistance Unit to the unused connector on the I/O Interface Unit.

Expansion I/O Racks, shown in the following diagram, can be used to expand

the CV-series PCs. There are five models of Expansion I/O Backplane that can

be used, as shown in the following table. These vary in the number of slots that

they provide for Units (other than the Power Supply Unit and I/O Interface Unit)

and in expansion capabilities. CV500 Expansion I/O Backplanes offer complete

expansion capabilities, while CVM1 Expansion I/O Backplanes do not support

I/O Interface Units and thus must be connected directly to the CPU Backplane

(see Single Expansion I/O Rack in this subsection).

An Expansion I/O Rack can be connected either directly to the CPU Backplane

(seeSingle Expansion I/O Rack in this subsection) or to an I/O Control Unit.Up to

seven Expansion I/O Racks can be connected to the I/O Control Unit on the CPU

Rack in two series unless an Expansion CPU Rack is connected, in which case

only six Expansion I/O Racks may be connected. If an Expansion CPU Rack is

connected, one of the series of Expansion I/O Racks is connected to the I/O

Control Unit on the CPU Rack and the other one is connected to the I/O Interface

Unit on the Expansion CPU Rack.

Attach a Termination Resistance Unit to the unused terminal on the I/O Interface

Unit of the last Expansion I/O Rack in each series. If two series of Expansion I/O

Racks are used, connect a Termination Resistance Unit to the last Rack in each.

If only one Expansion I/O Rack is required and no Expansion CPU Rack is used,

single Expansion I/O Rack can be connected directly to the CPU Rack without

a

an I/O Control Unit or I/O Interface Unit. The Racks are connected directly via the

connectors on the two Backplanes. Termination Resistance Units are also not

required. In every other respect, the Expansion I/O Rack is identical to Expan

-

sion I/O Racks in connected via I/O Control and I/O Interface Units.

Rack Components

Section 2-3

SYSMAC BUS/2 Slave

Racks

The SYSMAC BUS/2 Slave Racks use the same Expansion I/O Backplane and

Power Supply Unit as the Expansion I/O Racks, but a Remote I/O Slave Unit is

mounted instead of the I/O Interface Unit and the Slave Rack is connected from

the Remote I/O Slave Unit to a Remote I/O Master Unit on the CPU or Expansion

CPU Rack. Refer to the SYSMAC BUS/2 Remote I/O System Manual for details.

2-3 Rack Components

This section describes the main components that are used to construct CPU,

Expansion CPU, and Expansion I/O Racks.

2-3-1 CPUs

Six CPU models are available, the CV500-CPU01-EV1, CV1000-CPU01-EV1,

CV2000-CPU01-EV1,

Note The Memory Unit is built into CVM1/CV-series PCs; it is not necessary for the

user to install one, as is necessary for some C-series PCs.

Protect Keyswitch

The protect keyswitch write-protects the current PC Setup and user program

memory. The user program memory can also be write-protected by the using the

“Protect UM” function from the CVSS. When set to “SYSTEM PROTECT” this

switch will write-protect the entire user program memory even if only part of it is

protected using the “Protect UM” function from the CVSS.

To gain access to the DIP switches, open the cover of the Memory Card com-

partment as shown in the following figure. Turn off power to the PC before setting

the DIP switch.

Specifies whether the termination resistance is connected for the Host Link System. Turn this pin ON to

connect the terminal resistance. When RS-422 is used set this pin to ON at the last PC connected in the Host

Link System. When RS-232C is used, this pin does not affect Host Link System operation and may be set to

either ON or OFF.

To transfer the user program file (AUTOEXEC.OBJ) and the PC Setup (AUTOEXEC.STD) from the Memory

Card to the CPU on power application, set this pin to ON. If this pin is set to OFF, the PC Setup can be

changed from the CVSS so that only the user program (AUTOEXEC.OBJ) is transferred when power is

turned on. If program transfer is designated both with this pin setting and in the PC Setup, then both the

program file and the PC Setup will be transferred. The user program will not be transferred when the system

protect keyswitch on the front panel of the CPU is set to the SYSTEM PROTECT position, or memory is

write-protected from the CVSS.

When this pin is OFF, the communications settings for the host link interface are set in the PC Setup. Refer to

the CVSS Operation Manuals for details on the PC Setup.

Note: The above settings apply to CPUs manufactured from July 1995 (lot number **75 for July 1995). For

CPUs manufactured before July 1995 (lot number **65 for June 1995), only 1 stop bit will be set and the

baud rate will be 2,400 bps.

Memory Cards

Memory Cards can be used to store data or programs as files to expand the

memory storing capacity of the PC. Memory Cards fit into the slot located on the

lower left side of the CPU. Memory Cards are not provided with the PC and must

be ordered separately and installed in the CPU. There are three types of

Memory Cards that can be used for the CV-series PCs: RAM, EEPROM, or

EPROM.

RAM and EEPROM Cards

Data can be randomly written to and read from RAM or EEPROM Cards, making

it possible to easily stored programs. The memory of a RAM Cards is erased,

however, when power is not supplied to the CPU or when the RAM Card is re

-

moved from the CPU without first being connected to a backup battery. EE-

PROM Cards cannot be written while mounted in the CPU. Data can be written

to RAM Cards while they are mounted in the CPU by using the CVSS or by in

-

structions in the user program.

Both the RAM and EEPROM Memory Cards are equipped with write-protect

switches. Setting the write-protect switch to ON prevents data from being written

to or erased from the Card. Setting the write-protect switch to OFF allows data to

be written to or erased from the Card.

Four RAM Memory Card models are available, varying in memory capacity from

8K, 16K, 32K to 64K words. Two EEPROM Memory Card models are available,

one containing 8K words of memory and the other 16K words of memory.

RAM Card Backup Battery

Insert a battery into a RAM Memory Card before mounting the Card into the

CPU. Leave the battery in its holder. Battery life expectancies are given below

.

Replace the battery within the time listed. Refer to Section 4 Inspection and

EPROM Cards

Data contained in the ROM Card is stored on EPROM chips and cannot be al-

tered or erased during the CPU’s operation. The EPROM chip is mounted to the

Memory Card and the entire pack is installed in the CPU. Once data is written to

the chip, the data will not be lost when the power to the PC is OFF.

ROM Cards are shipped unprogrammed. The ROM Card can be programmed

using a CV500-MCWjj Memory Card Writer.

The procedure for erasing EPROM Memory Card data is as follows:

1, 2, 3...

1. Open the memory card cover by pressing at an angle on the catch at the

bottom edge of the card using a pointed object, such as a pen.

2. Erase the data from the EPROM chips by exposing the window of the

EPROM chips to ultraviolet light. Any of a number of commercially available

EPROM erasers may be used. To ensure complete erasure, the Memory

Card should be subject to a minimum exposure as specified by the eraser

manufacturer.

3. Close the cover and slide the catch back into place.

Rack Number Switch

Each Expansion I/O and Expansion CPU Rack is assigned a rack number from 1

through 7. Set the rack number on the rack number switch. Words are allocated

to Racks in order according to rack numbers, starting from the CPU Rack, which

is always rack number 0.

Set the rack number switch using a standard screwdriver. If a number other than

1

through 7 is assigned, or the same rack number is set to more than one Rack,

the PC will not operate

Note Turn OFF the power to the PC before setting the rack number switches.

Connector

The I/O Interface Unit CV500-II201 for Expansion I/O Racks provides a connec-

tor for connecting a Peripheral Device. One Peripheral Device (CVSS or Pro-

gramming Console) can be connected per to the CPU or I/O Interface Units for

each PC, although additional Peripheral Devices can be connected to Slave

Racks if a SYSMAC BUS/2 System is used. Whether mounted to the CPU or an

I/O Interface Unit, the operation of the Peripheral Device is the same.

Note When connecting a Peripheral Device to the CPU or an I/O Interface Unit, set the

baud rate of the CPU to 50k bps via the CPU DIP switch.

3-1-1 Mounting Units

To build a Rack PC, we start with a Backplane. The Backplane for a CV-series

PC is illustrated below.

The Backplane has two functions: it provides physical support for the Units that

are mounted to it and it provides the connectors and electrical pathways neces

-

sary for connecting the Units.

The first device we will mount to the Backplane is a Power Supply Unit. The Pow

er Supply Unit fits into the rightmost slot on the Backplane and provides electric

-

ity at the voltage required by the other Units in the PC. It can also be used to

power devices other than the PC if necessary and it enough current is available.

Power Supply Unit

The CPU is mounted next to the Power Supply Unit. The CPU fits into the posi

-

tion directly to the left of the Power Supply Unit.

CPU

40

Assembly

Section 3-1

The CV-series CPUs have no I/O points built in. In order to complete the PC we

need to mount one or more Units providing I/O points to the Backplane. Mount

the Units to the Backplane by pressing them firmly into position, making sure the

connectors are properly mated. Secure the Unit by tightening the mounting

screws located on the top and bottom of the Unit.

Mounting screws

Provided at the top and

bottom of the Unit.

Connector

Make sure the connectors

are properly mated.

The following figure shows one I/O Unit mounted directly to the left of the CPU.

Units other than the Power Supply Unit, the CPU, and the I/O Control Unit (see

below) can be mounted to any of the other slots on the CPU Rack.

I/O Unit

As you can see from the figure, there is still some space available to the left of the

I/O Unit. This space is for any additional Units that may be required.

The figure above shows a total of ten I/O Units mounted to the Backplane. These

I/O Units could be replaced by other Units, such as Special I/O Units, CPU Bus

Units, etc. I/O Units come in five shapes; A-, B-, C-, D- and E-shape (refer to Ap-

pendix B Specifications) each of which can be mounted to any of the ten slots.

The Backplane, Power Supply Unit, CPU, and other Units are collectively called

a CPU Rack.

41

Assembly

Section 3-1

If we want to include more than ten Units in our configuration, we can add an

additional Rack by mounting an I/O Control Unit to the leftmost slot of the CPU

Rack.

I/O Control Unit

Now we can use a cable to connect the CPU Rack to another Rack. This Rack

has a Power Supply Unit and I/O Units mounted to it, but it has no CPU of its own.

The additional Rack must also have an I/O Interface Unit mounted to its leftmost

slot to allow communications between the additional Rack and the CPU Rack.

The Backplane, Power Supply Unit, I/O Interface Unit, and other Units are col

-

lective called an Expansion I/O Rack or an Expansion CPU Rack. The differ-

ences between the various types of Rack and the types of Systems they can be

used in are described in earlier sections of this manual. A CPU Rack connected

to a single Expansion I/O Rack is shown below.

CPU Rack

I/O Interface Unit

The CPU Rack and Expansion I/O Rack shown above are connected by a cable

via the I/O Control Unit and I/O Interface Unit. It is possible to keep adding Ex

pansion I/O Racks in this way until the maximum number of I/O points for the

system is reached. Each Expansion I/O Rack requires an I/O Interface Unit, al

-

though a single Expansion I/O Rack can be connected by directly connecting the

CPU and Expansion I/O Backplanes, as described in an earlier section.

3-1-2 Memory Card and Expansion Data Memory Unit

Extra memory is available in two forms, via the use of Memory Cards or by using

an Expansion Data Memory Unit. This section outlines the procedure for mount

-

ing and removing these optional memory devices.

Memory Cards

The Memory Card can be used to store data and programs as files. Memory

Cards are optional and are not supplied with the CPU. They must be ordered

separately and installed by the user

Mounting a Memory Card

Mount a Memory Card to the CPU using the following procedure.

1. Open the cover of the Memory Card compartment.

1, 2, 3...

2. If the Memory Card is RAM or EEPROM, set the write-protect switch to OFF

so that data can be written to the Card.

3. Insert the Memory Card into its compartment. In doing so, a slight resistance

will be felt as the connector on the Memory Card mates with the connector

on the CPU. Continue pushing until the Memory Card is inserted completely

into the CPU. If the Memory Card ON/OFF switch is ON, the Memory Card

indicator will light.

4. Close the cover.

Mount the Expansion Data Memory Unit to the CV1000 CPU using the following

procedure.

1, 2, 3...

1. Turn OFF the power to the PC.

Caution Do not attempt to mount or remove the Memory Unit while the power to the PC is

ON. During mounting or removal, exercise care that you do not directly touch the

memory elements or connector pins of the Unit. Hold the Unit by the lever.

!

2. Remove the Expansion Data Memory Unit cover on the front panel of the

CPU by pushing the lever on the cover upwards, as indicated by the arrow

on the cover.

6. Attach the cover to the compartment.

When the Expansion Data Memory Unit is mounted to the CPU, the Expansion

Data Memory Unit is backed up by the battery in the CPU.

When the Unit has been removed from the CPU, the memory contents will be

retained for about 10 minutes by a backup capacitor built-in to the Unit, provided

that CPU power was ON and that the Unit was mounted in the CPU for at least 1

minute.

When removing the Expansion Data Memory Unit, be sure to turn ON the power

to the PC for more than 1 minute and then turn it OFF. At that time the capacitor

will be fully charged allowing it to be backed up for 10 minutes. The retention

period will be shorter if Memory Unit has been mounted (to the CPU) for less

than 1 minute.

3-2 Installation Environment

This section details the necessary environmental conditions for installing the

PC.

Caution Static electricity can damage PC components. Your body can carry an electro

-

!

static charge, especially when the humidity is low. Before touching the PC, be

sure to first touch a grounded metallic object, such as a metal water pipe, in order

to discharge any static build-up.

Ambient Conditions

Do not install the PC in any of the following locations. Doing so will affect PC life

and may affect operating performance.

• Locations subject to ambient temperatures lower than 0°C or higher than

55°C.

• Locations subject to drastic temperature changes or condensation.

• Locations subject to ambient humidity lower than 10% or higher than 90%.

• Locations subject to corrosive or flammable gases.

• Locations subject to excessive dust (especially iron dust) or chloride.

• Locations that would subject the CPU to direct shock or vibration.

• Locations that would subject the PC to water, oil, or chemical reagents.

• Locations exposed to direct sunlight.

Cooling

There are two points to consider in order to ensure that the PC does not over-

heat. The first is the clearance between the Racks, and the second is installation

of a cooling fan.

45

Mounting Racks

Section 3-3

Clearance between Racks

The Racks need to have sufficient room between each other to allow for I/O wir-

ing, and additional room to ensure that the I/O wiring does not hamper cooling.

The Racks must also be mounted so that the total length of the Connecting

Cable between all Racks in a given series does not exceed 50 m. As a general

rule, about 70 to 120 mm should be left between any two Racks. Consider fac

-

tors such as the width of the wiring duct, wiring length, ventilation, and ease of

access to Units, when determining the spacing between Racks. Greater space

is required between Racks when using certain CPU Bus and Special I/O Units.

Refer to the operation manuals for the Units you are using for details.

Cooling Fan

A cooling fan is not always necessary, but may be needed in some installations.

Try to avoid mounting the PC in a warm area or over a source of heat. A cooling

fan is needed if the ambient temperature may become higher than that speci-

fied. If the PC is mounted in an enclosure, install a cooling fan, as shown in the

following diagram, to maintain the ambient temperature within specifications.

Fan

PC

Louver

3-3 Mounting Racks

Each Rack must be mounted vertically, that is, with the printing on the front pan

-

els oriented as it would normally read. Racks may be directly mounted to any

sturdy support meeting the environmental specifications.

Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring

conduit should be used, and it should be long enough to completely contain the

I/O wiring and keep it separated from other cables.

46

Mounting Racks

Section 3-3

The duct work shown in the following diagram is not used for mounting the

Racks. Although optional, this duct work can be used to house the wires from the

I/O Units that run along the sides of the Racks, keeping the wires from becoming

entangled. This figures illustrate the correct way to mount the Racks.

3-4 Power Supply Units

Use a commercially available 100 to 120-VAC or 200 to 240-VAC power source

to supply power to the AC Power Supply Unit; a 24-VDC power, for the DC Power

Supply Unit. Expansion I/O Racks and Expansion CPU Racks must also be con

-

nected to a power source via a Power Supply Unit. If possible, use independent

power sources for the Racks, input devices, and output devices.

Supply power to the CPU Rack and Expansion CPU Rack from the same power

source. If supplied by separate sources or if power is not supplied to the Expan

-

sion CPU Rack, the CPU will not operate. It is also recommended that power to

the Expansion I/O Racks be supplied from the same power source as the CPU

and Expansion CPU Racks. In order to supply power to the Expansion I/O Racks

from separate power sources, turn on the power to the Expansion I/O Racks be

-

fore turning on power to the CPU Rack.

Supply power to the various parts of the system (power equipment, controls, PC

system, and DC I/O, etc.) via separate power supplies.

3-4-2 Grounding

The line ground (LG: ) terminal of the Power Supply Unit is a noise-filtered

neutral terminal. Short the line ground terminal to the ground (GR: ) terminal to

improve noise resistance.

To avoid electrical shock, attach a grounded AWG 14 wire (cross-sectional area

2

of 2 mm ) to the ground terminal. The ground resistance must be 100

W or less

and must be checked periodically to be sure that environmental conditions have

not deteriorated ground capacity. Do not use a wire longer than 20 m.

53

Power Supply Units

Section 3-4

PC operation may be adversely affected if the ground wire is shared with other

equipment or if the ground wire is attached to the metal structure of a building.

When using Expansion I/O Racks, the Racks must also be grounded to the

ground terminal. The same ground can be used for all Racks.

Power Supply Units

Section 3-4

The PC ignores all momentary power interruptions if the interruption lasts no

longer than 10 ms. If the interruption lasts between 10 and 25 ms, the interrup

-

tion may or may not be detected. If the supply voltage drops below 85% of the

rated voltage for longer than 25 ms (less for the DC Power Supply Unit), a power

interruption detection signal is output and program execution is halted.

If power is not restored within 10 ms (the power retention time) after the power

interruption detection signal is output, the PC stops operating and all outputs are

turned OFF.

If after power interruption detection, power is restored within a period defined as

the momentary power interruption time (default value: 0 ms), the CPU will re-

sume operation. If the momentary power interruption time elapses and power

has not been restored, the CPU will begin execution of the power OFF interrupt

program if one has been programmed. The CPU stops operating after the lapse

of the power retention time (10 ms).

Note The momentary power interruption time can be set to between 0 and 10 ms. For

details, refer to the CVSS Operation Manuals.

Caution If a C500 Expansion I/O Rack is connected to the PC, the momentary power in

-

!

terruption time setting is not effective and a power interruption of any length will

trigger shut down processing.

Automatic Recovery

Operation is resumed automatically when the voltage is restored to more than

85% of the rated value.

3-4-6 Current Consumption

The Power Supply Units are limited in the total current they can supply to Units

on the Racks. The following table shows the maximum current available on a

Rack for either model of Power Supply Unit. The available current shown in the

table is in addition to the current consumed by the Backplane, Power Supply

Unit, CPU, I/O Control Unit, I/O Interface Unit, and Peripheral Devices.

WARNING Always attach crimp terminals to the wires to ensure proper connection.

!

Connecting loose wires can cause fires.

Caution Abide by the following precautions when wiring the I/O Units. Failure to abide by

!

these precautions my cause faulty operation or damage to the Unit.

• Be sure that no wire clippings or other foreign materials enter the Units when

wiring.

• Check and recheck all wiring before supplying power to the system.

• Check and recheck terminal block before mounting them to the Unit.

Note 1. Putting I/O lines and high-tension lines or power lines in the same duct or

conduit may cause the I/O lines to be affected by noise. This may cause a

malfunction in the Unit or may damage the Unit or I/O devices.

2. Use reinforced insulation or double insulation on the DC power supply con

-

nected to DC I/O Units when complying with EC directives (low voltage).

3. Use separate power supplies for Relay Output Units and DC I/O Units when

complying with EC directives (low voltage).

3-5-1 Terminal Blocks

The terminal block of an I/O Unit can be removed by loosening the mounting

screws.

You do not have to remove the lead wires from the terminal block in or-

der to remove the block from an I/O Unit.

Terminal block mounting screws

Loosen the terminal block mounting screws to remove

the terminal block from the I/O Unit. Make sure the

mounting screws on the terminal block are tightened af

-

ter wiring is complete and the terminal block is re-

mounted to the I/O Unit.

3-5-2 Wiring Precautions

General

Electrical Noise

Take appropriate measures when any electrical device likely to produce noise is

connected to the PC as a load. Devices generating noise of more than 1,200 V

(such as electromagnetic relays and valves) require noise suppression. For

noise sources running on DC power, connect a diode in parallel with the coil of

each device.

When mounting a CPU Rack and an Expansion I/O Rack together on a mounting

plate, provide a ground to the mounting plate. The mounting plate must be plated

with a highly conductive surface in order to ensure noise immunity.

Inductive Load Surge

Suppressor

When an inductive load is connected to an I/O Unit, connect a surge suppressor

or diode in parallel with the load, as shown in the following diagram. The diode

will adsorb the back electromagnetic field generated by the load.

Input Leakage Current

When two-wire sensors, such as photoelectric sensors, proximity sensors or

limit switches with indicators are connected to the PC as input devices, the input

bit may be turned ON erroneously by leakage current. In order to prevent this,

connect a bleeder resistor across the input to reduce the input impedance.

If the leakage current is less than 1.3 mA, there should be no problem. If the leak

age current is greater than 1.3 mA, determine the value and rating for the bleed

er resistor using the following formulas.

Output Units

Output Short Protection

Output devices and Output Units can be damaged if the load connected to an

output terminal is shorted. Attach a fuse to the output circuit to protect your sys

-

tem. A fuse is recommended even if the Output Unit is provided with an internal

fuse (e.g., Transistor and Triac Output Units), to increase easy of maintenance

and provide extra protection.

Interlock Circuits

When the PC controls an operation such as the clockwise and counterclockwise

operation of a motor, provide an external interlock such as the one shown below

to prevent both the forward and reverse outputs from turning ON at the same

time.

Output Leakage Current

If a transistor or triac Output Unit is used to drive a low voltage load, the leakage

current may prevent the output device from turning OFF. To prevent this, con-

nect a bleeder resistor in parallel with the load as shown in the following table.

Wiring I/O Units

Section 3-5

Output Surge Current

When connecting a Transistor or Triac Output Unit to an output device having a

high surge current (such as an incandescent lamp), care must be taken to avoid

damage to the Output Unit. The Transistor and Triac Output Units are capable of

withstanding a surge current of ten times the rated current. If the surge current

for a particular device exceeds this amount, use one of the following circuit con

-

figurations to protect the Output Unit.

OUT

L

+

R

COM

The above circuit protects the Output Unit by letting the load draw a small current

(about one third the rated current) while the output is OFF, significantly reducing

the surge current. The following circuit reduces the surge current by employing a

current-limiting resistor.

Transistor Output Residual

Voltage

A Transistor Output Unit’s output cannot be directly connected to a TTL input

because of the transistor’s residual voltage. When connecting TTL circuits to

transistor Output Units, connect a pull-up resistor and a CMOS IC between the

two.

3-5-3 Wiring Examples

The following examples illustrate how to connect I/O devices to I/O Units. During

wiring, work slowly and carefully. If an input device is connected to an Output

Unit, damage may result. Check all I/O devices to make sure they meet the spec

ifications (refer to Appendix B Specifications). Be sure to allow for leakage cur

rents and load inductance.

3-6 Compliance with EC Directives

The following precautions must be abided by when installing CV-series PCs to

meet EC Directives.

1, 2, 3...

1. CV-series PCs are classified as open-structure devices and must be

installed inside a control panel.

2. Use reinforced insulation or double insulation on the DC power supply con

-

nected to CV500-PS211 Power Supply Unit and DC I/O Units.

3. Use separate power supplies for Relay Output Units and DC I/O Units.

66

Compliance with EC Directives

Section 3-6

4. The maximum switching capacity of the CV500-PS211 Power Supply Unit is

2

A at 24 VDC when complying with EC Directives (low-voltage directives).

5. CV-series PCs that meet EC Directives meet the common emission stan-

dard (EN50081-2) of the EMC Directives as individual products. When as

-

sembled into machinery, however, the noise generated by switching relay

outputs can fail to meet the standard. When noise is excessive, surge killers

must be installed or other measures must be taken outside of the PC. The

measures required to meet the standard will vary with the load being driven,

wiring, the configuration of the machinery, etc.

The following examples show means of reducing noise. These means will

only reduce the amount of noise and will not eliminate noise. They are pro

-

vided here as examples only.

Requirement

The following conditions can be used to determine if measures to reduce noise

are necessary. Refer to the EN50081-2 Standard for details.

• If the loads of the devices into which the PC is built are switched less than 5

times a minute, then no measures need to be taken.

• If the loads of the devices into which the PC is built are switched 5 times or

more a minute, then measures need to be taken.

Examples

Inductive Load Surge

Suppressor

Connect a surge suppressor or diode in parallel with the load, as shown in the

following diagrams, when switching inductive loads.

CR Method (AC or DC)

The reset time will be increased if the load is a relay, solenoid, or similar device.

Connect the CR between the load connections for 24-V and 48-V power supply

voltages and between the contact connections for 100 to 200-V power supply

voltages.

The capacitor and resistors can be based on the following guidelines.

C:

R:

0.5 to 1 µF for each amp of contact current

0.5 to 1 Ω for each volt of contact voltage.

You will need to adjust the above values depending on the characteristics of the

load, relay, etc., based on the discharge suppression of the capacitor when the

contacts are open and the current control effect of the resistor the next time the

circuit is closed.

The dielectric strength of the capacitor generally needs to be between 200 and

300 V. Use an AC capacitor (without polarity) in an AC circuit.

Inductive load

C

R

Power supply

Diode Method (DC Only)

The energy stored in the coil is impressed on the coil as a current by the action of

the parallel diode and converted to Joule heat by the resistance of the inductive

load. Here, the reset time will be increased even more than for the CR method.

67

Compliance with EC Directives

Section 3-6

The reverse dielectric strength of the diode must be 10 times the circuit voltage

and the forward current must be at least as high as that of the load. If the circuit

voltage is low enough, as it is for most electronic circuits, then the reverse dielec

-

tric strength of the diode can be as low as 2 to 3 times the circuit voltage.

Inductive load

Power supply

Varistor (AC or DC)

The method uses the fixed voltage characteristics of a varistor to prevent high

voltages from being applied to the contacts. Here, as well, the reset time will be

increase somewhat.

Connect the varistor between the load connections for 24-V and 48-V power

supply voltages and between the contact connections for 100 to 200-V power

supply voltages.

Inductive load

Power supply

Output Surge Current

When connecting an output device having a high surge current (such as an in-

candescent lamp), use one of the following circuit configurations to protect the

Output Unit.

The following circuit lets the load draw a small current (about one third the rated

current) while the output is OFF, significantly reducing the surge current.

are provided in the cable. Half-lock connectors use the S3200-COCF2511 and are compatible with C200H SYS

MAC LINK or SYSMAC NET Link Unit connectors. Full-lock connectors use the S3200-COCF2011 and are com

-

patible with CV-series SYSMAC LINK or SYSMAC NET and C1000H SYSMAC LINK Link Unit connectors. Full-

lock connectors cannot be used with C200H connectors.

The above connectors cannot be used with C500 SYSMAC NET Link Unit connectors, cable relays, or NSB. Refer

to the SYSMAC NET Link System Manual for appropriate connectors for these applications.

Note Each Optical Power Tester is provided with a replaceable Head Unit. There is no difference in type among

all Optical Power Testers except for the head unit. This means the S3200-CAT2000 Optical Power Tester,

for example, can be used as the S3200-CAT2700, S3200-CAT2820, or S3200-CAT3200 Optical Power

Tester by just replacing the Head Unit of the S3200-CAT2000 with those for the S3200-CAT2700,

S3200-CAT2820, or S3200-CAT3200.

Wiring Dynamic Inputs

When a large number of bits must be controlled, an ID212 DC Input Unit can simplify wiring by inputting status to up

to 64 bits through only 16 points. Using digital switches or a specially wired keyboard, the different combinations of

input points will determine which bits are ON. Two examples of connections using digital switches or a keyboard

are given.

115

Specifications

Appendix B

Connection Example 1 (Keyboard)

The wiring diagram and table below show how the ID212 DC Input Unit can be wired using a specially wired key

-

board. For example, if A on the keyboard is pressed, the combination of inputs on DA A 0 and STB 9 turn ON bit 00

T

of word n. Similarly, the combination of inputs on DATA 7 and STB 7 turn ON bit 15 of word n+3. The value of word n

depends on where the Unit is mounted.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance

between the DC Input Unit wires and high-tension equipment or power lines. If this cannot be avoided, use

shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m.

116

Specifications

Appendix B

Connection Example 2 (Digital Switches)

This example shows how the ID212 DC Input Unit can be wired using digital switches. Just as the keys on the

keyboard can turn ON different combinations of bits, the digital switches can control different combinations of bits.

For example, the combination of inputs on switch no. 1 and input point 00 turn ON bit 00 of word n. (For the sake of

simplicity, the figure below shows the digital switches wired to control 32 bits instead of 64 bits as was shown in

Example 1.) Wire STB 4, STB 5, STB 6, and STB 7 to access an additional 32 bits.

The graph below shows the value of the surge current and the time it takes the current to reach a steady state

(current-carrying time). The curved line in the graph represents the maximum value of surge current at which the

Unit can operate properly. It is suggested that when opening and closing a load with a large surge current, to keep

the value of the surge current to half the value shown the graph (within the shaded area).

Wiring Dynamic Outputs (3G2A5-OD211)

By using the OD211 DC Output Unit, a large number of outputs can be controlled through only 16 bits. Just like the

ID211 DC Input Unit, different combinations of bits can control different outputs. Using this type of Unit can simplify

wiring when many outputs must be controlled. Up to 64 outputs can be accessed.

Because the output data is positive logic, a terminal output goes high when the output bit is ON (1). A strobe output

is negative logic, so when the output bit is ON (1), the corresponding terminal goes low. Use positive logic output

devices for the load of this Unit. The strobe output is cyclic and automatically output.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance

between the DC Input Unit wires and high-tension equipment or power lines. If this cannot be avoided, use

shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m.
