LB/SC Diagnosis
The input loops of all versions are supervised, if the line fault detection is active (mandatory,
see datasheet). The related safety function is defined as the outputs are in fault state
(safe state), if there is a line fault detected.
Reaction Time
The reaction time for all safety functions is < 20 ms.
