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.
Installation
•Install the Units properly as specified in the relevant operation manual(s). Improper 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 locking devices are properly locked into place. Improper locking may result in malfunction.
Wiring and Connection
•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
Application Precautions |
5 |
•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 wiring cuttings from entering the Units.
•Attach the labels supplied with CPM1A or CPM2C Units or provide other protective 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 dissipation. Leaving the labels attached may result in malfunction.

•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 supply. 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.
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 discharge 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 being 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.
•When using a Temperature Sensor Unit with a thermocouple input (CPM1A-TS001/002, CPM2C-TS001), observe the following precautions:
•With the CPM1A-TS001/002, do not remove the cold junction compensator attached at the time of delivery. If the cold junction compensator is removed the Unit will not be able to measure temperatures correctly.
xxii
Application Precautions |

PC Setup |
Section 1-1 |
1-1 PC Setup
|
The PC Setup comprises various operating parameters that control PC opera- |
|
tion. 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, howev- |
|
er, 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:
•DM 6645 to DM 6655:
Accessed only when program execution begins.
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 effec- |
|
tive, 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 |
The PC Setup can be read, but not overwritten, from the user program. Writing |
Programming Device |
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 |
|
menu operations. All other settings must be made using the hexadecimal setting |
|
operation. |
|
• Startup Mode (DM 6600) |
|
• I/O Hold Bit Status and Forced Status Hold Bit Status (DM 6601) |
|
• Cycle Monitor Time (DM 6618) |
|
• Cycle Time (DM 6619) |
|
• RS-232C Port Settings (DM 6645 to DM 6649) |
|
Note The RS-232C Port Settings (DM 6645 to DM 6649) are not used in |
|
CPM1/CPM1A PCs because these PCs aren’t equipped with an RS-232C port. |
Errors in the PC Setup |
If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B) will |
|
be generated, the corresponding error flag (AR 1300 to AR 1302) will be turned |
|
ON, and the default setting will be used instead of the incorrect setting. |

Note 1. When the startup mode is set to continue the operating mode last used before 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.)

Section 1-1 |
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.
