xx
5 Application Precautions
Observe the following precautions when using the PC System.
Caution Failure to abide by the following precautions could lead to faulty operation of the
!
PC or the system, or could damage the PC or PC Units. Always heed these precautions.
Designing Circuits or Creating Ladder Programs
• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes.
• Construct a control circuit so that power supply for the I/O circuits does not
come ON before power supply for the Unit. If power supply for the I/O circuits
comes ON before power supply for the Unit, normal operation may be temporarily interrupted.
• If the operating mode is changed from RUN or MONITOR mode to PROGRAM
mode, with the IOM Hold Bit ON, the output will hold the most recent status. In
such a case, ensure that the external load does not exceed specifications. (If
operation is stopped because of an operating error, including errors generated
by FALS instructions, the values in the internal memory of the CPU Unit will be
saved, but the outputs will all turn OFF.)
• For models with only the super-capacitor installed, the contents of the READ/
WRITE enable area of the DM area, HR area, AR area, and CNT data area
may be damaged if the power is turned OFF for a long time. To prevent such
damage, provide ladder program that will check AR 1314 to ensure proper operation of the system.
• The life of relays largely varies depending on switching conditions. Be sure to
test operating conditions using actual Units and use the product within the specified number of switchings so as not to cause any performance problems. Using the product with performance problems may result in defective insulation
between circuits or burning of the relays.
5Application Precautions
Installation
Wiring and Connection
• Install the Units properly as specified in the relevant operation manual(s). Im-
proper installation of the Units may result in malfunction.
• Do not install the PC or PC Units in places where the Units may be affected by
excessive noise. Doing so may result in malfunction.
• Install the Units properly so that they will not fall off.
• Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in the relevant manuals. Incorrect
tightening torque may result in malfunction.
• Install the Expansion I/O Unit connector cover to the last Expansion I/O Unit to
prevent dust or foreign matter from entering inside the Unit. Not doing so may
result in malfunction.
• Be sure that the terminal blocks, expansion cables, and other items with lock-
ing devices are properly locked into place. Improper locking may result in malfunction.
• Be sure to use cables as specified in the relevant manual(s).
• Install external breakers and take other safety measures against short-circuit-
ing in external wiring. Insufficient safety measures against short-circuiting may
result in burning.
• When wiring signal lines, do not place them in the same duct as high-voltage
lines or power lines. Doing so may result in malfunction.
xxi
• Be sure that terminal blocks and connectors are connected in the specified
direction with the correct polarity. Not doing so may result in malfunction.
• Leave the labels attached CPM1 or CPM2A Units when wiring to prevent wir-
ing cuttings from entering the Units.
• Attach the labels supplied with CPM1A or CPM2C Units or provide other pro-
tective covers when wiring to prevent dust or wiring cuttings from entering the
Units.
• Remove the labels after the completion of wiring to ensure proper heat dissipa-
tion. Leaving the labels attached may result in malfunction.
• Use the connectors and wiring materials specified in the relevant manual(s).
• Be sure to wire according to the relevant manual(s). Incorrect wiring may result
in burning.
I/O Connection and System Startup
• Disconnect the functional ground terminal when performing withstand voltage
tests.
• Always use the power supply voltages specified in the operation manual(s). An
incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied. Be particularly careful in places where the
power supply is unstable.
• Do not apply voltages to the input terminals in excess of the rated input voltage.
Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess of the
maximum switching capacity. Excess voltage or loads may result in burning.
• Double-check all wiring and switch settings before turning ON the power sup-
ply. Incorrect wiring may result in burning.
• Check the user program for proper execution before actually running it on the
Unit. Not checking the program may result in an unexpected operation.
5Application Precautions
Handling Precautions
• When using, storing, or transporting the product, keep within the specifications
listed in the relevant manual(s).
• Confirm that no adverse effect will occur in the system before attempting any of
the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Before touching a Unit, be sure to first touch a grounded metallic object to dis-
charge any static built-up. Not doing so may result in malfunction or damage.
• Do not touch the Expansion I/O Unit Connecting Cable while the power is be-
ing supplied to prevent any malfunction due to static electricity.
• Do not pull on the cables or bend the cables beyond their natural limit. Doing
either of these may break the cables.
• Do not place objects on top of the cables. Doing so may break the cables.
• When disposing of Units or other products, be sure to do so according to local
laws and regulations.

1-1SectionPC Setup
1-1 PC Setup
The PC Setup comprises various operating parameters that control PC operation. In order to make the maximum use of PC functionality when using interrupt
processing and communications functions, the PC Setup may be customized
according to operating conditions.
At the time of shipping, the defaults are set for general operating conditions, so
that the PC can be used without having to change the settings. You are, however, advised to check the default values before operation.
Default Values The default values for the PC Setup are 0000 for all words (except for the low
battery error enable in DM 6655 bits 12 to 15 for CPM2A CPU Units). The default
values can be reset at any time by turning ON SR 25210 in PROGRAM mode.
Caution When data memory (DM) is cleared from a Programming Device, the PC Setup
!
settings will also be cleared to all zeros.
1-1-1 Changing the PC Setup
PC Setup settings are accessed at various times depending on the setting, as
described below.
• DM 6600 to DM 6614: Accessed only when PC’s power supply is turned
ON.
• DM 6615 to DM 6644: Accessed only when program execution begins.
• DM 6645 to DM 6655: Accessed regularly when the power is ON.
Since changes in the PC Setup become effective only at the times given above,
the PC will have to be restarted to make changes in DM 6600 to DM 6614 effective, and program execution will have to be restarted to make changes in
DM 6615 to DM 6644 effective.
When DM 6602 bits 00 to 03 are set to protect the program memory, DM 6602
cannot be changed using the PC Setup operation of the Support Software. To
change DM 6602, use the I/O Monitor or DM Edit operation.
Making Changes from a
Programming Device
Errors in the PC Setup If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B) will
The PC Setup can be read, but not overwritten, from the user program. Writing
can be done only by using a Programming Device.
Although the PC Setup is stored in DM 6600 to DM 6655, settings can be made
and changed only from a Programming Device (e.g., SSS, or Programming
Console). DM 6600 to DM 6644 can be set or changed only while in PROGRAM
mode. DM 6645 to DM 6655 can be set or changed while in either PROGRAM
mode or MONITOR mode. The cycle time will be rather long when the PC Setup
is changed in MONITOR mode.
The following settings can be made in PROGRAM mode from the SSS using

1-1-2 CPM1/CPM1A PC Setup Settings
The PC Setup is broadly divided into four categories: 1) Settings related to basic
PC operation and I/O processes, 2) Settings related to the cycle time, 3) Settings
related to interrupts, and 4) Settings related to communications. This section will
explain the settings according to these classifications.
The following table shows the settings for CPM1/CPM1A PCs in order. Refer to
the page number in the last column for more details on that setting.

Note 1. When the startup mode is set to continue the operating mode last used be-
fore the power was turned off, that operating mode will be retained by the
built-in capacitor. If the power remains off for longer than the backup time of
the capacitor, the data may be lost. (For details on the holding time, refer to
the CPM1A or CPM1 Operation Manual.)

2. Do not set to “05” to “07.” If set to this value, the CPM1/CPM1A will not operate properly and the RUN PC Setup Error Flag (AR 1302 ON) will not turn
ON.
3. Retention of IOM Hold Bit (SR 25212) Status
If the “IOM Hold Bit Status at Startup” (DM 6601, bits 08 to 11) is set to “Maintain” with the IOM Hold Bit (SR 25212) turned ON, operation can be started
with the I/O memory (I/O, IR, LR) status just as it was before the power was
turned OFF. (The input area is refreshed at startup, however, so it is overwritten by the most recently updated input status.)
Retention of Forced Status Hold Bit (SR 25211) Status
If the “Forced Status Hold Bit Status at Startup” (DM 6601, bits 12 to 15) is
set to “Maintain” with the Forced Status Hold Bit (SR 25211) turned ON, operation can be started with the forced set/reset status just as it was before
the power was turned OFF. (When starting up in RUN Mode, however, the
forced set/reset status is cleared.)
Even if the “IOM Hold Bit Status at Startup” or “Forced Status Hold Bit Status
at Startup” is set to “Maintain,” the IOM Hold Bit (SR 25212) or Forced Status
Hold Bit (SR 25211) status may be cleared if the power remains OFF for
longer than the backup time of the built-in capacitor. (For details on the holding time, refer to the CPM1A or CPM1 Operation Manual.) At this time the
I/O memory will also be cleared, so set up the system so that clearing the I/O
memory will not cause problems.
4. The transmission delay is the delay between the previous transmission and
the next transmission.
