What am I doing wrong? SF Light is Off I am monitoring the outputs in the HW config and it shows them on. Module Info: Relay output module SM 322; DO 8 x Rel. AC 230 V/5 A; (6ES7322-1HF10-0AA0)

Check that the nothing reset your output from the software. use cross reference to be sure that the outputs are used once in your software. Hope this helps.
