Note
If your application requires UL certification, please observe the note regarding the digital
output in Section Technical data, CU250S-2 Control Unit (Page 385).
Generally, you determine the pre-assignment of the functions of the inputs and outputs
during the basic commissioning.
Control Units, where you cannot change the pre-assignment, to not offer this step in the
basic commissioning. In this case, you must adapt the functions of the inputs and outputs
depending on the specific plant or system, as described in Section Adapt terminal strip
(Page 95).
Even if you have selected a pre-assignment in the basic commissioning, you can adapt the
individual inputs and outputs depending on the specific plant or system, as described in
Section Adapt terminal strip (Page 95).
You can find an overview of the standard assignment or the possible pre-assignments in
Section: Selecting the pre-assignment for the terminal strip (Page 60).
For a fail-safe input, you require two "standard" digital inputs.
