Diagnostic Request DINT W
To request a diagnostic value, the appropriate ID must be
sent to the module using the parameter Diagnostic
Request (see Chapter

As soon as Diagnostic Response returns the ID of
Diagnostic Request (see

Diagnostic Status contains the diagnostic value
requested.

Diagnostic Response.
The IDs of Diagnostic Request and Diagnostic Response
can be evaluated in the user program. Diagnostic Status
only contains the requested diagnostic value when both
Diagnostic Request and Diagnostic Response have the
same ID.

Using the parameter Restart on Error, each I/O module
that has switched off permanently due to faults can be
forced to re-adopt the RUN state. To do this, set the
Restart on Error parameter FALSE to TRUE.
The I/O module performs a complete self-test and only
enters the RUN state if no faults are detected.
