Module interrupts (STEP 7)
You can assign parameters to diagnostic and hardware interrupts for modules
having analog inputs with STEP 7.
For
modules with analog outputs

it is possible to configure diagnostic interrupts.
Triggering a diagnostic interrupt
With a coming or going event – for example, wire break fault – the module triggers
a diagnostic interrupt if the ”enable diagnostic interrupt” parameter has been
assigned.

MAINS OFF/MAINS ON for the ET 200X is required following rectification of the
configuration/parameter-assignment error.
The CPU interrupts the processing of the user program and processes the
diagnostic interrupt block (OB 82). The event that led to the interrupt is entered in
the start information of OB 82.
