The input module distinguishes between types of error and
responds accordingly with:
– Channel passivation if a failure can be allocated to
precisely that channel (e.g. with detection of shorts across
contacts).
– Module passivation if the error that occurs cannot be
allocated precisely to one channel and a component
defect is not detected (e.g. communication failure with
PROFIsafe).
– Safe shut-down if a single microcontroller detects the
failure of a component that is required to run the
program.
– Passivation as a result of the incorrect setting of
a function mode.
The input module can only transmit certain error messages as
a function of the selected function mode.
