Diagnostic messages

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.
Note
Parallel connection of two outputs
For parallel connection of two outputs for redundant control of a load, the channel
diagnostics "Short-circuit to L+" and "Wire break" must be deactivated.
