Switching of zone sets

For each zone set, a unique combination of signals must be defined at the control inputs.
To prevent unintended switching of the monitored zone sets, two consecutive zone sets
must differ in at least two positions in the assigned signals at the control inputs.
In the PSENscan Configurator the automatic assignment ensures a difference in exactly
two positions.
Pilz recommends that the automatic assignment by the PSENscan Configurator is used.
