Open load detection not possible!
When connecting a digital power output to a digital input directly, open load
detection is not possible for this power output Ox+. Set the Open load detection
parameter to "not active" because otherwise the F I/O module is passivated and
the "Open load" diagnostic message is output.
Open load detection is not safety related and cannot be part of the safety
function under any circumstances.
Note about the Short circuit parameter
If you connect a digital power output Ox+ to a digital input, you have to set the
Short circuit parameter to "not active". Otherwise, the F I/O module is
passivated and the "Short circuit" diagnostic message is output.

Motor)
Important information about single-channel use!
The single-channel use of an output for a safety function is only permitted if 1-
fault safety is not required! With single-channel use, shutdown must be ensured
by the standard control in the event of an error. This can be achieved by
integrating a 2nd disconnection faculty (e.g., a line contactor K0) in the safety
application.

You can connect a contactor to a digital power output and connect a motor
single-channel using normally open contacts of the contactor. Connection is
