How to configure safety relays
If you want to control a safety relay or contactor with the FSO module, define the use
of the related I/O with these parameters. See also section
on page
Do not configure a safety function activation to a safety relay feedback. In addition,
you have to connect the safety relay to the desired safety function. Set the same
digital output as you set for the safety relay as the output of the desired safety
function. In this example, safety relay 1 is connected to the SBC function.
