1-3 Basic Configuration

This diagram shows some of the possible field devices for the Analog I/O

Units. Any I/O device can be used as long as voltage/current requirements

fall within the specified ranges.

The I/O device connected to the Analog I/O Unit will often serve as an inter-

face for another device. For example, a preamplifier may amplify the output

of a pressure gauge to the level required for the Analog Input Unit and a reg-

ulator may interface a heating system to control temperature.

1-5 System Considerations

Number of Units

C200HS/C200H/C200HX/HG/HE Analog I/O Units are classified as Special I/O

Units. A maximum total of ten Special I/O Units (including PC Link Units) can be

mounted to the CPU Rack, Expansion I/O Racks, and Slave Racks of a single

PC. A single C200H-NC211 Position Control Unit counts as two Units.

The Units that belong to the various Special I/O Unit groups are shown in the

following table. Their usage is limited according to the maximum current pro-

vided for the Rack and the amount of current consumed by each Unit. For de-

tails, refer to the C200HS/C200H Installation Guide.

Slave Racks

Certain limitations apply to the number of Special I/O Units that can be mounted

on Slave Racks. The following table shows the maximum number of Group A, B,

C, and D Special I/O Units that can be mounted on a single Slave Rack when

only Units of that group are used.

If Units from any of the four groups are to be combined, then both of the following

two equations must be satisfied.

3A + B + 2C + 6D x 12

A + B + C + D x 8

Units can be mounted on other Racks as well, until the maximum total of ten

Units has been reached. Remember, though, that a single C200H-NC2111 Posi-

tion Control Unit counts as two Units. PC Link Units must also be counted among

the total of ten Units.

System Configuration

Considerations

C200HS/C200H Special I/O Units are allocated IR area words according to the

unit number switch settings on their front panels. They do not use the words of

the slots in which they are mounted. For details regarding data area allocations,

refer to 2-2 and 3-2 IR and DM Bit Allocations.

With the C200H, do not mount an Analog I/O Unit in the two slots adjacent to the

CPU. Doing so would block peripheral devices such as the Programming Con-

sole from being connected.

Special I/O Units cannot be used on a C200H Remote I/O Slave Rack if the

Slave Rack is connected to different model PC (i.e., C500, C1000H, or

C2000H).

Precautions

Be sure to turn off the power supply to the PC before installing or disconnecting

Units or connecting lines.

To reduce the risk of malfunctioning due to electrical noise, wire input and output

lines in separate ducts from high-voltage and power lines.

For further wiring precautions, refer to the respective sections on wiring for Ana-

log Input Units and Analog Output Units.

Note 1. The unit number setting switch is factory set to 0.

2. If two or more Special I/O Units are assigned the same unit number, an I/O

UNIT OVER error will be generated and the PC will not operate.

3. Make the unit number settings with the power turned off to the PC. If the set-

tings are made with the power on, they will not go into effect until either the

power is turned off and then on again or the Special I/O Unit Restart Flag

(AR0100 to AR0109) is turned ON.

Number of Inputs

There can be 1, 2, or 4 inputs depending on the settings of pins 1 and 2, as

shown in the table below.

0: OFF

1: ON

The following table shows the effects of the various pin combinations. If there is

no need to use all of the inputs, processing time can be shortened by setting the

pins so that the smallest possible number of inputs is enabled.

user’s option at any input.

Data Reading Mode

In normal mode, the input data is read only once before being converted from

analog to digital. In filter mode, the input data is read three times and then

the average values are converted from analog to digital. This helps to reduce

the effects of electrical noise and so on. Using filter mode, however, results in

longer processing time, as shown in the following table.

The same input range is used for all of the inputs for a particular Unit. The voltage

range of 1 to 5 V and the current range of 4 to +20 mA, however, can be used at

the user’s option at any input.

Use the DIP switch on the back panel of the Unit to set the input range and the

number of inputs. (For details, refer to 2-1-2 Switch Settings.)

When current input is used, short circuit the voltage input (+) and current input

(+) terminals.

The common terminal is connected to the 0 V of the Analog Input Unit’s analog

circuit. Noise interference can be reduced by using shielded cables for input

lines.

The A8 and B9 terminals are short circuited internally.

Considerations

When wiring inputs, apply the following points to avoid noise interference and

optimize Analog Input Unit performance.

• Use shielded twisted-pair cable for external connections and power lines.

• Route input cables separately from the AC cable, and do not run the Unit’s

cables near a main circuit cable, high voltage cable, or a non-PC load cable.

• Be sure to install surge-absorbing diodes or surge absorbers for inductive

loads (relays, solenoids, electromagnetic valves, etc.) They should be

installed right next to relays and solenoids. Use surge-absorbing diodes with a

dielectric strength of at least five times the circuit voltage.

• If there is noise interference from power lines (if, for example, the power supply

is shared with electrical welding devices or electrical discharge machines, or if

there is a high-frequency generation source nearby) install a noise filter at the

power supply input area.

• Use at least a class-3 ground (to 100 Ω or less), with as heavy a wire as pos-

2

sible (i.e., at least 1.25 mm ).

2-2 Bit and DM Area Allocations

IR Area Allocation

C200H Analog Input Units are allocated ten words each from the portion of the

IR area (IR 100 to IR 199) that is reserved for Special I/O Units. The words that

are allocated a particular Analog Input Unit depend on the setting of the unit

number on the front panel of the Unit. Those ten words are then reserved as an

I/O refresh data area, and the bits that comprise that area are refreshed with ev-

ery I/O refresh scan by the PC.

Note The unit number that is set for an Analog Input Unit must not be used for any

other Special I/O Unit. If the same unit number is set more than once, an I/O

UNIT OVER error will be generated and operation will be stopped.

Note 1. This bit turns ON under the following conditions:

• An input is 0.5 V or less when set for 1 to 5V.

• An input is 2 mA or less when set for 4 to 20 mA.

• The input does not function when set for 0 to 10 V.

2. The Setting Error Flag turns ON when the scaling upper and lower limits are

not in BCD or when the number of mean processing terms is 0000 or not in

BCD.

3. Even if scaling or mean processing are not executed, and regardless of

whether or not inputs are used, the data described in note 2 will cause the

Setting Error Flag to turn ON. This will have no effect on operation, however.

lower limit is smaller than the upper limit.

3. The range for setting the number of times that sampling is to be executed for

mean value processing is 0002 to 9999 (BCD).

the upper limit in the leftmost word, and make sure

that the lower limit is smaller than the upper limit.

correspond to inputs 1 to 4.

2-3 Functions and Programming

The C200H-AD001 Analog Input Unit provides six functions:

• Input signal range setting

• Square root

• Scaling

• Mean value

• Peak value

• Input disconnection detection

These functions are set using Unit switches and Peripheral Devices, such as a

Programming Console. The words allocated to the Unit in the DM Area (DM m to

DM m+11) cannot be written from user program and all data set in these words

must be written from a Peripheral Device.

When inputting data from a Programming Console, use the operations to

change present values. When inputting from the SSS (SYSMAC Support Soft-

ware), use the DM editing operations.

The data set in the DM area is transferred to the Analog Input Unit when either of

the following steps is taken. Be sure to perform one or the other of these steps

whenever new data has been set or data has been changed.

• Turning ON the power to the C200H/C200HS/C200HX/HG/HE CPU.

• Turning ON the Restart Bit allocated to the Unit as a Special I/O Unit (AR 0100

to 0109).

Any or all of the six functions can be used at the same time. Data will be pro-

cessed in the following sequence and the final results will be output to words n+1

to n+4: analog-to-digital conversion → square root → scaling → mean value →

peak value.

18

Functions and Programming

Section 2-3

2-3-1 Input Signal Range Setting

The C200H-AD001 can convert analog input signals in three ranges:

0 to 10 V, 1 to 5 V, or 4 to 20 mA. The range is set on pin 3 of the DIP switch

as shown below

Pin 3

OFF

Input range

1 to 5 V

4 to 20 mA

0 to 10 V

If the 0 to 10 V setting is used, it must be used for all four inputs. The 1 to 5 V

and 4 to 20 mA ranges can be used at the same time for different inputs.

The digital data is in 12-bit binary code (0000 to 0FA0), and resolution is

1/4000 full scale.

Note An offset error is likely to occur when power is turned on. The full scale of con-

verted data is 4000, and the remaining 95 is used for offset/gain.

2-3-2 Square Root

The square root function is used to convert quadratic data, such as thermocou-

ple inputs, to linear data. The function is activated for all inputs when the Square

Root ON Bit (IR 1n012, where n is the unit number) is turned ON.

The square root function can be used at the same time as the scaling and mean

value functions. If all three functions are used, the square root of the converted

input value is taken first and then scaling and mean value calculations are per-

formed.

The square root function uses an 80-bit floating decimal system. Only the

integer value is kept, the remainder is truncated.

Square root value = √(converted input value (BCD) × 4000)

Note If the Square Root ON Bit (IR 1n012, where n is the unit number) is turned ON,

square root calculations will be performed for all inputs.

19

Functions and Programming

Section 2-3

2-3-3 Scaling

The scaling function automatically converts the analog input signal to a preset

range for use in specific engineering applications. The scaling function is ex-

ecuted for an input when its Scaling Bit is ON, i.e., it can be set separately for

each input. This function can be used at the same time as other functions.

To set this function for an input, turn ON the Scaling Bit corresponding to that

input in word n.

Data set in the DM area is transmitted when the Unit is turned on or initial-

ized. If data is modified in the middle of a session, then the modified data

becomes effective the next time the Unit is turned on, or by toggling the ap-

propriate Special I/O Restart Bit in the AR area.

Scaled data is calculated using the formula below. Only the integer value is

kept, the remainder is truncated.

Scaling data =

Note 1. Scaling will not be performed and unscaled (normal) data will be output if the

contents of DM words allocated to the Unit is not BCD or if a lower limit is

greater than the corresponding upper limit.

2. The Setting Error Flag (bit 00 in IR 1n5, where n is the unit number) will be

turned ON if the contents of DM m to DM m+7 is not BCD.

3. The Setting Error Flag will turn ON whenever DM area data is not BCD re-

gardless of whether an input is being used and regardless of whether or not

scaling is set. Operation, however, will be normal in these cases.

Resolution

If the difference between an upper limit and the corresponding lower limit (upper

limit – lower limit) is 4000 or greater, the resolution is fixed at 1/4000. If the differ-

ences is less than 4000, the resolution will be reduced proportionately.

For example, if the upper limit minus the lower limit is 2000, the resolution is

1/2000.

2-3-4 Mean Value

The mean value function sums a specified number of terms of converted input

data and divides by the number of terms preset the DM area.

If the Mean ON Bit for an input is ON (bits 07 to 10 of word n), the mean value will

be output to the corresponding word in the PC. The desired number of terms

must be set in the corresponding word in the DM area between DM m+8 and

DM m+11. The setting can be between 0002 and 9999 (BCD).

Functions and Programming

Section 2-3

The mean value functions can be used in combination with any of the other func-

tions.

Set the mean data for each input with the Programming Console. This data

cannot be changed from the user’s program. Set the mean data for all 4 in-

puts even when using only one input. If there is a mistake in the data for

even 1 input, the Setting Error Flag will be activated, though operation will

continue.

The mean value is calculated using the formula below. When the Mean En-

able Bit turns ON, the converted data will read “0000” until the mean value is

calculated for the first time.

Sum of converted input values

Mean value =

Number of terms (mean data)

The maximum mean function conversion time = 2.5 ms × the sum of the

number of terms for all inputs

Note 1. Mean value calculation will not be performed and normal data will be output

if the number of terms set in the DM area is 0000 or is not BCD.

2. The Setting Error Flag (bit 00 in IR 1n5, where n is the unit number) will be

turned ON if the number of terms set in the DM area is 0000 or is not BCD.

3. The Setting Error Flag will turn ON whenever the number of terms set in the

DM area is 0000 or is not BCD regardless of whether an input is being used

and regardless of whether or not scaling is set. Operation, however, will be

normal in these cases.

2-3-5 Peak Value

The peak value function holds the maximum output value for every input. This

function can be used at the same time an any or all of the other functions.

The output value that will be held is one of the following depending on what other

functions are set: converted input value, scaled value, mean value, and square

root. Data will be processed in the following sequence and the maximum value

of the final results will be output to words n+1 to n+4: analog-to-digital conver-

sion → square root → scaling → mean value → peak value.

The peak value function is activated for all 4 inputs when the Peak Value ON Bit

(IR 1n011, where n is the unit number) is turned ON and reset when it is turned

OFF.

Note If the Peak Value ON Bit (IR 1n011, where n is the unit number) is turned ON, the

peak value will be held for all inputs.

Mean and Peak Values

Data will be output as illustrated below when both the mean value and the peak

value functions are used. In this example, mean value #2 will be output as the

The Input Disconnect Flags will be turned ON when an the input signal level is

less than 0.5 V/2 mA and the input signal range is set at 1 to 5 V/4 to 20 mA.

These flags will not turn ON when the input signal range is set at 0 to 10 V.

The Input Disconnect Flags are contained in in word IR n+5, as shown below.

Note 1. The Input Disconnect Flags will operate only when the Conversion Inhibit Bit

(bit 00 of IR n) is OFF.

2. Input disconnection is detected for all input set on pins 1 and 2 of the back-

panel DIP switch. If an input that is not being used (i.e., not connected) is

specified on the DIP switch, the Input Disconnect Flag will turn ON.

3. The current peak value will be held even if a disconnected input is detected.

Detection When Errors

Occur

When an error occurs, the contents are output to the SR and HR areas. The fol-

lowing tables show the various errors that may occur, along with their probable

causes and remedies.

Unit error

Probable causes and operations

• Causes of error

Possible remedies

Disconnection error

Check the input signal wires, terminal

block, and input voltage.

• Input signal wire is disconnected.

• Input signal range is set to “1 to 5V” but input is 0.5

V or less.

• Input signal range is set to “4 to 20 mA” but input is

2 mA or less.

• Disconnect indications

• BROKEN WIRE indicator is lit.

• The Input Disconnect Flag (IR n+5, bits 01 to 04)

that corresponds to the erroneous input signal is

turned ON (except when the input range is 0 to

10 V).

Setting error

The data set in the DM area is wrong. In this case,

the Setting Error Flag (IR n+5, bit 00) will be ON.

Check the contents of the data.

Output disabled

The converted data is unstable, as, for example,

when the power is first turned on. In this case, the

Output Disabled Flag (IR n+5, bit 08) will be ON.

Functions

The following table briefly outlines the basic functions of the C200H-DA001.

These functions are covered in more detail in 3-3 Functions and Programming.

Function

Explanation

Output range setting

The output range can be set according to the output signal level that is to be used. The

same output range is used for all of the outputs for a particular Unit. The voltage range

of 1 to 5 V and the current range of 4 to 20 mA, however, can be used at the user’s

option at any output.

Output limit

The output limit function sets upper and lower limits on the output signal. The upper and

lower limits are preset in the DM area. The output remains at the limit level as long as

the output limit function is activated.

Output limit alarm

This function activates an alarm if the output signal is outside of the range defined by

the upper and lower limits preset in the DM area, but it does not alter the output level. It

is possible to include a deadband, which delays the resetting of the alarm. The output

limit alarm turns ON and OFF according to the following conditions.

Pulse output

This function creates a 0 V to 5 V pulse output separate from the analog output.

Note 1. The unit number setting switch is factory set to 0.

2. If two or more Special I/O Units are assigned the same unit number, an I/O

UNIT OVER error will be generated and the PC will not operate.

3. Make the unit number settings with the power turned off to the PC. If the set-

tings are made with the power on, they will not go into effect until either the

power is turned off and then on again or the Special I/O Unit Restart Flag

(AR0100 to AR0109) is turned ON.

34

Before Operation

Section 3-1

Output Wiring

Considerations

When wiring outputs, apply the following points to avoid noise interference and

optimize Analog Output Unit performance.

• Use shielded twisted-pair cable for external connections and power lines.

• Route output cables separately from the AC cable, and do not run the Unit’s

cables near a main circuit cable, high voltage cable, or a non-PC load cable.

• Be sure to install surge-absorbing diodes or surge absorbers for inductive

loads (relays, solenoids, electromagnetic valves, etc.) They should be

installed right next to relays and solenoids. Use surge-absorbing diodes with a

dielectric strength of at least five times the circuit voltage.

DC Relay

AC Relay

Surge absorber

Surge-absorbing diode

(Example: ERB44-06,

by Fuji Electric)

Solenoid, etc.

Surge absorber

• If there is noise interference from power lines (if, for example, the power supply

is shared with electrical welding devices or electrical discharge machines, or if

there is a high-frequency generation source nearby) install a noise filter at the

power supply output area.

• Use at least a class-3 ground (to 100 Ω or less), with as heavy a wire as pos-

2

sible (i.e., at least 1.25 mm ).

Caution When using the C200H-DA001 Analog Output Unit, a voltage (current) may be

output momentarily from the output terminal when the power supply to the PC is

turned ON or OFF.

!

Approximately 10 V will be output for approximately 1 second after the power is

turned ON or OFF.

If this causes a problem, provide countermeasures so that the power supply or

output timing of external devices differs from the ON/OFF timing of the power

supply to the PC.

Bit and DM Allocations

Section 3-2

3-2 Bit and DM Allocations

IR Allocations

C200H/C200HS Analog Output Units are allocated ten words each from the por-

tion of the IR area (IR 100 to IR 199) that is reserved for Special I/O Units. The

words that are allocated a particular Analog Output Unit depend on the setting of

the unit number setting switch on the front panel of the Unit. Those ten words are

then reserved as an I/O refresh data area, and the bits that comprise that area

are refreshed with every I/O refresh scan by the PC.

meantime will remain invalid until then.

3. The values set in DM are used for both output lines (i.e., for output 1 and

output 2).

4. m = 1000 + 100 x unit number.

3-3 Functions and Programming

The C200H-DA001 Analog Output Unit provides 4 functions

• Output signal range setting

• Output limit

• Output limit alarm

• Pulse output

These functions are set using Unit switches and Peripheral Devices, such as a

Programming Console. The words allocated to the Unit in the DM Area (DM m to

DM m+4) cannot be written from user program and all data set in these words

must be written from a Peripheral Device.

When inputting data from a Programming Console, use the operations to

change present values. When inputting from the SSS (SYSMAC Support Soft-

ware), use the DM editing operations.

The data set in the DM area is transferred to the Analog Output Unit when either

of the following steps is taken. Be sure to perform one or the other of these steps

whenever new data has been set or data has been changed.

38

Functions and Programming

Section 3-3

• Turning ON the power to the C200H/C200HS CPU.

• Turning ON the Restart Bit allocated to the Unit as a Special I/O Unit (AR 0100

to 0109).

3-3-1 Output Signal Range Setting

The C200H-DA001 converts 12-bit binary data (3-digit hexadecimal) from the

PC to analog output in one of three ranges: 0 to 10 V, 1 to 5 V, or 4 to 20 mA.

The C200H-DA001 can convert analog output signals in three ranges:

0 to 10 V, 1 to 5 V, or 4 to 20 mA. The range is set on pin 1 of the DIP switch

as shown below.

Pin 1

OFF

Input range

1 to 5 V

If the 0 to 10 V setting is used, it must be used for all two outputs. The 1 to

5 V and 4 to 20 mA ranges can be used at the same time for different out-

puts.

3-3-2 Output Limits

The output limit function can be used to establish upper and lower limits for the

output signal. The limits can be used to restrict the output for any of a number of

possible reasons, e.g., to prevent unsuitable outputs from occurring even when

incorrect data is set.

This function can be used at the same time as the output limit alarm function.

The upper and lower limits are preset as binary values in the DM area (lower limit

in DM m and upper limit in DM m+1). The output will remain between the upper

and lower limits as long as the output limit function is activated.

39

Functions and Programming

Section 3-3

If the output goes beyond either limit, an Output Limit Flag (bits 05 to 08 in IR

n+3) will turn ON and the output will remain at the limit value

Use the following procedure to set upper and lower limits.

1, 2, 3...

1. Set the lower and upper limits in DM m and DM m+1. The setting range is

between 0000 and 0FFF (binary data). Set the limits from the Programming

Console. This data cannot be changed from the user’s program.

Note Calculations of the desired limit can be made as shown in the follow-

ing example. To set an upper limit of 8 V for a 0 to 10 V range setting,

use the following equation and set the results (0CCC) in DM m+1:

8/10 x 0FFF = 0CCC

2. Turn power to the PC off then then back on or turn ON the Special I/O Unit

Restart Bit allocated to the Unit (AR 0100 to AR 0109).

3. Turn ON the Output Limit ON Bit for the desired output:

Output 1 Limit ON Bit: Bit 06 of IR n+2

Output 2 Limit ON Bit: Bit 07 of IR n+2

Functions and Programming

Section 3-3

3-3-3 Output Limit Alarms

This function activates an alarm if the output signal is outside of the range de-

fined by the upper and lower limits preset in the DM area, but it does not alter the

output level. It is possible to include a deadband, which delays the resetting of

the alarm.

Time

This function can be used at the same time as the output limit function.

The output limit alarms turn ON and OFF according to the following conditions.

Upper limit:

ON:

analog output ≥ output limit alarm upper limit

OFF: analog output < output limit alarm upper limit – deadband width

Lower limit:

ON:

analog output ≤ output limit alarm lower limit

OFF: analog output > output limit alarm lower limit + deadband width

When any of the Output Limit Alarm Flags turn ON, the ALARM indicator on

the Unit will light and signals will be generated on external terminals A7, A8,

B7, and B8 (refer to 3-1-3 Wiring for details).

Use the following procedure to set upper and lower limit alarms.

1, 2, 3...

1. Set the lower and upper alarm limits in DM m+2 to DM m+4. The setting

range is between 0000 and 0FFF (binary data). Set the limits from the Pro-

gramming Console. This data cannot be changed from the user’s program.

Note Calculations of the desired limit can be made as shown in the follow-

ing example. To set an upper limit alarm at 4.75 V for a 1 to 5 V range

setting, use the following equation and set the results (0F00) in

DM m+1:(4.75 – 1)/(5 – 1) x 0FFF = 15/16 x 0FFF = 0F00

2. Turn power to the PC off then then back on or turn ON the Special I/O Unit

Restart Bit allocated to the Unit (AR 0100 to AR 0109).

3. Turn ON the Output Alarm ON Bit for the desired output:

Output 1 Alarm ON Bit: Bit 04 of IR n+2

Output 2 Alarm ON Bit: Bit 05 of IR n+2

41

Functions and Programming
