Measures to Take
1)Display the check screen to see if the input signal is sent in answer to the STM command executed on occurrence of the alarm. If two or more commands are given, give the commands one by one in MDI operation to find out which STM command causes the alarm.
2)If “0” is set at the OPTIONAL PARAMETER (CYCLE TIME OVER CHECK) Cycle/STM time over alarm level, the alarm B
2295 STM time over occurs instead of this alarm.
