I have a SNAP-PAC-R1 turning on relays using a SNAP-ODC-32-SRC. Intermittently I have one particular output that does not turn on (IVAL turns ON but XVAL stays OFF). No error is generated. I have worked around the problem by continuously turning on the point when it is needed. Is there a way to check the XVAL of a digital output point so I can record exactly when this error occurs and log the frequency? Not sure if the memory map read commands copies the IVAL or XVAL of output points, since these should always be the same.
p.s. I have contacted support and they recommended I re-seat all i/o and controller and make sure modules are screwed down; I did this but it didn’t help.
