Evaluation
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
F 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 F I/O module do not change.

To monitor protective devices, you can connect the normally open contact of a
protective door switch to four digital inputs of the F I/O module.
For more information about configuring the F I/O module, read section
"Parameterization of the F I/O module with the WAGO Parameterization Tool".
Set the Dual channel evaluation parameter for the digital inputs used to "yes".
So that the signal lines of the digital inputs of the F I/O module are monitored for
