Pay attention to the protected installation of signal lines during short
circuit test "inactive"!
If you have set the Short circuit test parameter of an input to "inactive", the
signal lines must be installed protected among each other and between the
sensors and inputs according to EN 60204-1 or EN ISO 13849-2 (e.g., as
separate sheathed lines or in separate cable ducts).
Alternative measures for fault detection!
You can take alternative measures (e.g., antivalent evaluation) for fault detection
to achieve the required risk reduction for your application (e.g., SIL3/Cat.4/PL e).
The safety parameters of the F I/O module do not change.

For simple emergency off applications without signal fault security, you can use a
digital input for your safety function.
