7.2 Digital output terminals
The controller has
• three parameterisable output terminals (DO1 ... DO3) for outputting digital signals
• a relay output (terminal strip X101),
• a (high-current) output for controlling a brake (terminal strip X107).

Note!
Initialisation behaviour:
• After mains switching up to the start of the application, the digital outputs remain set
to FALSE.
Exception handling:
• In case of a critical exception in the application (e.g. reset), the digital outputs are set
to FALSE considering the terminal polarity parameterised in C00118 .
Switching cycle diagnostics of the relay:
• A reference for evaluating the wear limit can be obtained via the number of switching
cycles of the relay displayed in C00177/2 .
