Evaluation
Pay attention to the protected installation when the short circuit test is
activated!
With clock outputs T1 ... T2, you can install the signal lines from maximum two
sensors 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 are installed protected among
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).

To monitor protective devices, you can connect the normally open contact of a
protective door switch to four digital inputs of the PROFIsafe I/O module.
For more information about configuring the PROFIsafe I/O module, read section
"Parameterization of the PROFIsafe 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 PROFIsafe I/O module are
monitored for short circuits, set the Short circuit test parameter for all inputs to
"active". You must set the Valence evaluation parameter to "Antivalent". In
addition, set the Discrepancy time parameter to the discrepancy time required for
the normally open contact of the protective door switch.
You can achieve SIL3, Cat. 4/PL e with this switching.
