Error and message
Error and message
The following error messages appear for errors that occur after program exe-
cution has been started. PC operation and program execution will continue
after one or more of these error have occurred. The POWER, RUN, and
ALARM indicators will be lit and the ERR indicator will not be lit for any of
these errors. The RUN output will be ON.
The following error messages appear for errors that occur after program exe-
cution has been started. PC operation and program execution will stop and
all outputs from the PC will be turned OFF when any of the following errors
occur. All CPU indicators will not be lit for the power interruption error. For all
other fatal operating errors, the POWER, and ERR indicators will be lit and
the RUN indicator will not be lit. The RUN output will be OFF.
Watchdog timer has exceeded 100
ms.
Backup battery is missing or it’s
voltage has dropped.
Power has been interrupted for at
least 10 ms.
Watchdog timer has exceeded
maximum setting (default setting: 130
ms).
Memory Unit is incorrectly mounted or
missing or parity error has occurred.
END(01) is not written anywhere in
program.
Error has occurred in the bus line
between the CPU and Units.
Probable cause
Probable cause
Program cycle time is longer then
desirable. Reduce cycle time if
possible.
Check battery and replace if
necessary.
Check power supply voltage and
power lines. Try to power-up again.
Restart system in PROGRAM mode
and check program. Reduce cycle
time or reset watchdog timer if longer
time required. (Consider effects of
longer cycle time before resetting).
Check Memory Unit to make sure it is
mounted and backed up properly.
Perform a Program Check Operation
to locate cause of error. If error not
correctable, try inputting program
again.
Write END(01) at the final address of
the program.
Check the CPU Left/Right selector
switch on the Expansion I/O Unit.
Check cable connections between the
Units and Racks.
