5-4-2 Fatal Errors

72
The SRM1 is equipped with a variety of self-diagnosis functions to help identify
and correct errors that might occur and reduce down time.
Errors are divided into two categories based on their severity. Fatal errors are
more serious errors which stop SRM1 operation. Non-fatal errors are less seri-
ous and don't stop SRM1 operation.
SRM1 operation and program execution will continue after one or more of these
errors have occurred. Although SRM1 operation will continue, the cause of the
error should still 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.
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 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.
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 SRM1 can be set so that this error won't be detected.)
If an error occurs in CompoBus/S communications, the COMM indicator will be off
and the ERC indicator will be lit. There is no error flag. Check the Slave and the
connecting cables and restart.
The COMM indicator will be OFF if an error occurs in communications through the
Peripheral Port or RS-232C Port. AR 0804 will be ON if an error occurred in
communications through the RS-232C port. AR 0812 will be ON if an error occurred in
communications through the peripheral port. Check the connecting cables and restart.
SRM1 operation and program execution will stop and all outputs from the SRM1
will be turned OFF when any of these errors have occurred. SRM1 operation
cannot be restarted until the SRM1 is turned off and then on again or the Pro-
gramming Console is used to switch the SRM1 to PROGRAM mode and clear
the fatal error.
