Diagnostics alarms
A diagnostics alarm is generated and the DIAG-LED flashes on the module for each
diagnostics event. You can read out the diagnostics alarms, for example, in the diagnostics
buffer of the CPU. You can evaluate the error codes with the user program.
In DQ mode, the module outputs the following diagnostic alarms:

Solution
•
•
•
Use a different actuator type or modify
the wiring, for example, use cables with
larger cross-section
Connect the cable
Disable diagnostics
Correct the parameter assignment
