The two main contacts of the Emergency Stop button are supplied with 24 V
(three-terminal concept) via the PLC output. This PLC output is used for the
forced checking procedure of the inputs and outputs (refer to Chapter 7.3.6
"Test stop"). The individual circuits of the Emergency Stop button are
separately connected to the PLC and NCK inputs.
