PLC operation and program execution will continue after one or more of these
errors have occurred. Although PLC 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 indicator will flash.
Meaning and appropriate response
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 PLC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.
AR 1300 ON: An incorrect setting was detected in the PLC 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 PLC Setup (DM 6615 to
DM 6644) when switching to RUN or MONITOR mode. Correct the settings in PRO-
GRAM Mode and switch to RUN or MONITOR mode again.
AR 1302 ON: An incorrect setting was detected in the PLC Setup (DM 6645 to
DM 6655) during operation. Correct the settings and clear the error.
The cycle time 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 CPM2B can be set so that this error won't be detected.)
If the voltage of the C500-BAT08 backup battery is below the minimum level, the ERR
indicator will flash and SR 25308 will be turned ON.
Replace the battery. (See 8-6 Battery Replacement for details.)
PLC operation and program execution will stop and all outputs from the PLC
will be turned OFF when any of these errors have occurred. CPM2B operation
can't be restarted until the PLC is turned off and then on again or a Program-
ming Device is used to switch the PLC to PROGRAM mode and clear the fatal
error.
All CPU Board indicators will be OFF for the power interruption error. For all
other fatal operating errors, the POWER and ERR indicators will be lit. The
RUN indicator will be OFF.
Meaning and appropriate response
Power has been interrupted for more than 2 ms.
Check power supply voltage and power lines. Try to power-up again.
AR 1308 ON: There is a non-existent bit or word address in the user program. Check the
program and correct errors.
AR 1309 ON: An error has occurred in flash memory. Replace the CPU Board.
AR 1310 ON: A checksum error has occurred in read-only DM (DM 6144 to DM 6599).
Check and correct the settings in the read-only DM Area.
AR 1311 ON: A checksum error has occurred in the PLC Setup. Initialize the PLC Setup
and input the settings again.
AR 1312 ON: A checksum error has occurred in the program. Check the program and
correct any errors detected.
AR 1313 ON: A checksum error has occurred in the expansion instructions data and all
function codes have been set the their default values. Reset the expansion instructions.
AR 1314 ON: Data was not maintained in an area specified for holding. Clear the error,
check the data in the areas specified for holding, and try again.
END(01) is not written in the program. Write END(01) at the end of the program.
