There are two kinds of operating errors, non-fatal and fatal. PC operation will
continue after a non-fatal error occurs, but operation will be stopped if a fatal
error occurs.
Investigate all errors, whether fatal or not. Remove the cause of the error as
soon as possible and restart the PC. Refer to the CPM1 Operation Manual ,
CPM2A Operation Manual , or CPM2C Operation Manual for hardware informa-
tion and Programming Console operations related to errors. Refer to the SSS
Operation Manual for SSS operations related to errors.
PC operation and program execution will continue after one or more of these er-
rors have occurred. Although PC operation will continue, the cause of the error
should be corrected and the error cleared as soon as possible.
When one of these errors occurs, the POWER and RUN indicators will remain lit
and the ERR/ALM indicator will flash.
An FAL(06) instruction has been executed in the program. Check the FAL number to
determine conditions that would cause execution, correct the cause, and clear the
error.
An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.
AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to DM
6614) when power was turned on. Correct the settings in PROGRAM Mode and turn
on the power again.
AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to DM
6644) when switching to RUN Mode. Correct the settings in PROGRAM Mode and
switch to RUN Mode again.
AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to DM
6655) during operation. Correct the settings and clear the error.
If the voltage of the CPM2A-BAT01 or CPM2C-BAT01 backup battery is below the
minimum level, the ERR/ALM indicator will flash and SR 25308 will be turned ON.
Replace the battery.
Watchdog timer has exceeded 100 ms. (SR 25309 will be ON.)
This indicates that the program cycle time is longer than recommended. Reduce cycle
time if possible. (The PC Setup can be set so that this error won't be detected.)
Note ** is 01 to 99 or 9B.
