When measuring DC voltage from L on DQ terminals (of all the DI/DQ modules) to M on PLC, do you see ~24VDC? When measuring from M to GND, do you read ~0VDC? When measuring from DQ terminal currently associated with a DigOut that's on (according to the associated green LED) do you see 0V or 24VDC to GND / M (assuming M to GND is 0VDC)? Shine a strong light along side the installed terminals and make sure they are not offset by 1 pin. If a pin is visible on either end, power the system down, remove and correctly reinstall the DQ terminal block(s) as needed so no pin is visible on either end of the terminals (if needed). Post back your results.
