See the heading “The Drum Sequencer Function” for more
information.
Installing the CPU on the DIN Rail
The CPU and connecting carriers must be
installed on the same section of 35mm x
7.5mm DIN rail. The rail must have a
conductive (unpainted) finish for proper
grounding. For best stability, the DIN rail
should be installed on a panel using
screws spaced approximately 6 inches
(5.24cm) apart.

Activating or Replacing the Backup Battery
______________
Observing the Module LEDs _________________________
PWR
The LEDs indicate the presence of power and show the
operating mode and status of the CPU.
The CPU is shipped with a battery already installed. The battery holder
is located in the top side of the CPU module. Before the first use,
activate the battery by pulling and removing the insulator tab.
OK
RUN
FAULT
FORCE
PORT 1
PORT 2
To replace the battery, use a small screwdriver to gently pry open the
battery holder. Replace battery only with IC200ACC001 from your PLC
supplier, or with Panasonic battery: BR2032. Use of another battery
may present a risk of fire or explosion.
POWER
OK
ON when the CPU is receiving 5V power from the power
supply. Does not indicate the status of the 3.3V power
output.
ON indicates the CPU has passed its powerup diagnostics
and is functioning properly. OFF indicates a CPU problem.
Fast blinking indicates the CPU is running its powerup
diagnostics. Slow blinking indicates the CPU is configuring
I/O modules. Simultaneous blinking of this LED and the
green Run LED indicates the CPU is in boot mode and is
waiting for a firmware download through port 1.
Caution
Battery may explode if mistreated.
Do not recharge, disassemble, heat above 100 deg.C (212 deg.F) or
incinerate.
Autoconfiguration __________________________________
RUN
Green when the CPU is in Run mode. Amber indicates the
CPU is in Stop/IO Scan mode. If this LED is OFF but OK is
ON, the CPU is in Stop/No IO Scan mode.
At powerup, the CPU by default automatically generates a configuration
that includes all of the modules that are physically present in the
system, starting at slot 1. Autoconfiguration stops at the first empty slot
or faulted module.
If RUN is flashing green and the Fault LED is ON, the
Run/Stop switch was moved to Run position while a fatal
fault existed.
Switching the PLC Operating Mode ____________________
FAULT
ON if the CPU is in Stop/Faulted mode because a fatal fault
has occurred. To turn off the Fault LED, clear both the I/O
Fault Table and the PLC Fault Table. If this LED is blinking
and the OK LED is OFF, a fatal fault has occurred during
self-diagnostics. Please contact PLC Field Service.
The CPU Run/Stop mode switch
is located behind the module
door. This switch can be used to
RUN/ON
place the CPU in Stop or Run
mode. By default. Run/Stop mode

operation is enabled. The same
switch can also be configured to
prevent writing to program or
configuration memory and forcing
or overriding discrete data. It
defaults to disabled memory
protection.
PORT 1 & 2 Blinking indicates activity on that port.
Using the CPU Serial Ports __________________________
The CPU’s two serial ports are software-configurable for SNP slave, RTU
slave, or Serial I/O operation. If a port is being used for RTU, it automatically
switches to SNP slave mode if necessary. Both ports’ default configuration
is SNP slave mode. If configured for Serial I/O, a port automatically reverts
to SNP slave when the CPU is in Stop mode.
Run/Stop Mode Operation ____________________________
Either port can be software-configured to set up communications between
the CPU and various serial devices. An external device can obtain power
from Port 2 if it requires 100mA or less at 5VDC.
If Run/Stop mode switch operation is enabled, the switch can be used
to place the CPU in Run mode.
If the CPU has non-fatal faults and is not in Stop/Fault mode, placing
the switch in Run position causes the CPU to go to Run mode. Faults
are NOT cleared.
Port 1 is an RS-232 port with a 9-pin female D-sub
PORT 1
connector. It is used as the boot loader port for
upgrading the CPU firmware. The pinout of port 1
If the CPU has fatal faults and is in Stop/Fault mode, placing the switch
in Run position causes the Run LED to blink for 5 seconds. While the
Run LED is blinking, the CPU switch can be used to clear the fault
table and put the CPU in Run mode. After the switch has been in Run
position for at least ½ second, move it to Stop position for at least ½
second. Then move it back to Run position. The faults are cleared and
the CPU goes to Run mode. The LED stops blinking and stays on.
This can be repeated if necessary.

allows a simple, straight-through cable to connect
with a standard AT-style RS-232 port. Cable
shielding attaches to the shell. Port 1 screw locks
are threaded #4-40.
Port 2 is an RS-485 port with a 15-pin female D-sub
connector. This can be attached directly to an RS-
485 to RS-232 adapter (IC690ACC901). Port 2
screw locks are threaded (metric) M3x0.5).
RS232
PORT 2
If the switch is not toggled, after 5 seconds the Run LED goes off and
the CPU remains in Stop/Fault mode. Faults stay in the fault table.

Cable Lengths and Baud Rates
Maximum cable lengths (the total number of feet
from the CPU to the last device) are:
Port 1 (RS-232) = 15 meters (50 ft.)
Port 2 (RS-485) = 1200 meters (4000 ft.)
Both ports support configurable baud rates from
4800 to 38.4k bps.

Firmware Upgrades ______________________________
Operating Notes/Restrictions _______________________
CPU001 firmware resides in FLASH memory. This firmware may
be upgraded via serial download from an appropriate personal
computer to CPU serial port 1 (RS-232). Firmware upgrades
through port 2 (RS-485) are not supported.
1. If the input to a trigonometric function is either infinity or “not a
number” (NaN), the output result is indeterminate.
Avoid the use of infinity or not a number inputs.
2. If large real exponent values are input to the Real Exponential function
block, the output values are indeterminate.
To determine the current version of firmware on an existing
CPU001, connect a programmer to the CPU and look in the
Status/Memory Information.
3. When autoconfiguring a system at powerup, if multiple intelligent
modules (modules other than basic I/O modules) are present in the
system, some may not be configured. They are instead logged as extra
modules.
Upgrading CPU001-BA
: Any CPU001 version BA may be
upgraded to version BB.
Upgrading CPU001-AA:
Any CPU001-AA with a date code of
Either clear the hardware configuration or store a valid
configuration to resolve this problem.
903 or greater may be upgraded to version BB without updating the
hardware. (Date code is a 3-digit code found just below the Bar
Code marking on the CPU module). AA models with date codes
prior to 903 require a hardware modification; these units are not
field upgradable to version BB.
4. In rare instances, the CPU watchdog timer may expire if a booster
power supply is power-cycled and the CPU power supply is not power
cycled. This only occurs of there is an intelligent module that receives
its power from a booster power supply. When the watchdog timer
expires, it causes a CPU reset and fatal PLC fault.
To upgrade the firmware of a CPU001 to Release 1.10 use
Upgrade Kit #44A747796-G01.
To avoid this problem, supply power to the CPU and associated
booster power supplies from the same source.
5. An END function must not be used within a subblock (subroutine).
Execution of this function within a subblock causes a fatal CPU fault.
Use of END function blocks should normally be reserved for program
debug. If needed for this purpose, they may only be used within the
main program.
Problems Fixed
1. The state of the Force LED on the CPU is maintained if the CPU is
power-cycled.
2. Hold Last State, if configured for input modules, is handled correctly if
the module is “lost”.
3. Fault Status bits %SC009-13 are updated when the CPU is powered
up after having been powered down without a battery for a long time.

During the first sweep the Active Step is initialized.
The Active and Preset Step of the Drum Sequencer's control block
must be initialized for the Drum Sequencer to work or to pass power
flow. Even if the Active Step is in the correct range(between 1 and
length of the pattern array) and the Preset Step is not used, the drum
will not function if the Preset Step is not in the proper range.
If a Dwell Time is specified the drum can not sequence into
its next step until the Dwell Time has expired.
This optional input array of words has one element for each
element in the Pattern array. Each value in the array
represents the fault timeout for the corresponding step of the
