In general, I always try to avoid shorting the outputs by using intermediate conventional or solid state relays. Therefore, unfortunately, I cannot state whether it is possible to determine which output is short-circuited.

I think that the state of a short circuit can be determined only in those modules where there are solid-state PNP outputs. For npn, most likely, this function does not work.

One more moment - it is not known for sure whether the SDW5 -6  bits remain on when there is no command to turn on the output. Therefore, it is probably necessary to programmatically make logic that will remember in DW the state of this register and disable the outputs until the user confirms that all problems have been eliminated.

Contact support@unitronics.com with this question and post the answer here in the thread.
