Digital outputs
The controller is provided with a parameterisable digital output and a relay output.
6.3.1
Terminal assignment/electrical data
Note!
Initialisation behaviour:
• After mains switching up to the start of the application, the digital output
remains set to FALSE.
Exception handling:
• In case of a critical exception in the application (e.g. reset), the digital output
is set to FALSE considering the functional direction parameterised in
Switching cycle diagnostics:
• Code
serves to evaluate the load of the relay by querying the
switching cycles.
