Error code specification
With a specified error code of the CPU module as a trigger, data is to be collected. The occurrence timing of trigger varies
depending on the error type: continuation error or stop error.
■
At the occurrence of a continuation error
The occurrence timing of trigger is at the time of END processing of the scan where an error has occurred.
In the following situations, the occurrence of a continuation error that is specified as a trigger condition is not recognized as a
trigger, with no data collection:
• After the occurrence of a continuation error that is specified as a trigger condition, the same error, or a continuation error,
has occurred again.
• In the situation that a continuation error of 15 or more has occurred, a continuation error that is specified as a trigger
condition has occurred.
Being recognized as a trigger requires the error to be cleared.
■
At the occurrence of a stop error
The occurrence timing of trigger is at the time of occurrence of an error.
To specify an annunciator number as a trigger condition, employ device specification to specify any desired
annunciator number.
