Connection of the Digital Inputs
The digital inputs can be used as source inputs or as sink inputs.
NOTICE!
Risk of malfunctions in the plant!
A ground closure, e. g. caused by a damaged cable insulation, can bridge
switches accidentally.
Use sink inputs when possible or make sure that, in case of error, there will be
no risks to persons or plant.
