6.3.1.2 Emergency Off Connection, Dual channel, Equivalent Evaluation
Pay attention to the protected installation of signal lines during short circuit
test "not active"!
If you have set the Short circuit test parameter of an input to "not active", 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 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).

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.
Use the WAGO parameterization tool to set the parameters. 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 to "yes" for the digital inputs used
and the Valence evaluation parameter to "equivalent". In addition, set the
Discrepancy time parameter to the discrepancy time required for the two
switching elements.
