﻿The relay of a switching output can be configured as NO or NC contacts. In this way, the inversion of switching states is possible.

NO contact: Switching state = OFF ("0") ->
Relay contact opened
Switching state = ON ("1") ->
Relay contact closed 

NC contact: Switching state = OFF ("0") ->
Relay contact closed
Switching state = ON ("1") ->
Relay contact opened
