Hint: If you use a 1-channel digital output without the diagnostic pulses but you connect a
status indication of the output back to an FSO module input, for example, by using an external
auxiliary contact, you can use the safety data for
1-ch. DO, pulses in the calculations instead of
the data for 1-ch. DO, no pulses . (You do not need to include the safety data of the feedback, in
other words the data for the input to which the status indication is connected.)
