Mitsubishi Electric MELSEC iQ-F FX5 - Combining trigger conditions

20 MEMORY DUMP FUNCTION
20.2 Trigger Condition
199
20
At the occurrence of a stop error
Even if an error occurs, if the function (analog function, etc.) does not cause SM0 to turn ON, memory dump
using SM0 as the trigger cannot be executed. By specifying a device for each function's error display with the
device specification, memory dump can be executed even when an error occurs in a function that does not
cause SM0 to turn ON.
Combining trigger conditions
A trigger can be generated with trigger conditions combined. This combination is based on an OR condition. The
establishment of a condition, either device specification or error code specification, results in data collection.
Precautions
If the trigger conditions are established again during data collection, the state will not be recognized as a trigger so data will
not be collected.
If the trigger conditions for both device specification and error occurrence are established within the same
scan, the trigger conditions for error occurrence will have priority.
