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.
7.3.2 Connection Example for Digital Inputs in Rotary Table
Operating Mode (1 of N)
Use of the Rotary Table Operating Mode
If you have set the Operating Mode to the "Rotary Table" value (1 of N), the
temporal logic evaluation of the input bits must be performed by a suitable
function block in the safe PLC. Do not use the process image of the digital inputs
in the safe PLC without the suitable function blocks.

If you have set the Operating mode parameter to "Rotary table" using the
WAGO parameterization tool, you can connect the normally open contacts of a
mode selector switch or several rotary table sensors to the digital inputs of the
F I/O module. For more information on configuring the F I/O module, read section
"Parameterization of F I/O module with WAGO Parameterization Tool"
By setting the Operating mode parameter to Rotary table, clock output T2 is
switched off by the F I/O module module permanently.
Set the Short circuit test parameter for all digital inputs to "active" and the Two-
channel analysis parameter to "no".
Then connect the normally open contacts of the mode selector switch to the
digital inputs and the common clock line of the mode selector switch to clock
output T1. The process image of the digital inputs now contains the switch setting
of the mode selector switch.
