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).

Pay attention to the protected installation when the short circuit test is
activated!
With the two clock outputs T1 and T2, you must install the signal lines from
maximum two contiguous input channels in one common cable. Otherwise, the
PROFIsafe I/O module cannot detect short circuits between signal lines of the
inputs that are tested with the same clock output. Make sure that the signal lines
that belong to the same clock output T1 or T2 are installed protected against each
other and between the safe sensors 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 PROFIsafe I/O module do not change.

For emergency off applications that require single fault security, you can connect
two digital inputs via two switching elements (two-channel emergency off
switches with two break contacts) to the PROFIsafe I/O module.
