The input module distinguishes between types of error and
responds accordingly with:
– Channel passivation if a failure can be allocated to pre­
cisely that channel (e.g. with cross-circuiting detection).
– Module passivation if the fault that occurs cannot be al­
located precisely to one channel and no component de­
fect is 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 pro­
gram.
– Passivation as a result of the incorrect setting of a func­
tion mode.
The input module can only transmit certain error messages as
a function of the selected function mode.
