For the creation of the Signal Safe State, the following signals can be called upon via
p10039[0...3]:
– Power removed (STO active)
– SS1 active
– SS2 active
– SOS active
– SLS active
The different signals selected through p10039 are logically linked by means of OR
operation. Result of these logic operations is the "Safe State".
