The Omron CS1W-SCU31-V1 is a CS1W-series communications module that seats on the CS Series backplane, addressed as a slot card alongside the CPU and the rest of the I/O rack. Field-side termination is a D-Sub connector on the module face — the same gender and pitch convention used elsewhere in the CS1W comm line — so it lands in installations wired for serial CompoWay/F or Host Link drops rather than the RJ45 ethernet footprint of the ETN-series cards.
The CS1W-SCU21-V1 is the closest functional sibling in the same CS1W series — same backplane slot, same D-Sub termination, same CS Series host. The procurement-relevant differences are the agency mark (CSA / UL on the SCU21 vs cULus on the SCU31) and a 0.441 lb vs 0.551 lb card body.
Listed type is Communications Module in the CS1W series, terminating at a D-Sub on the field side and seating on the CS Series backplane.
Yes — both are CS1W-series backplane communications modules with the same D-Sub field-side footprint, so the panel wiring carries straight over. The panel declaration pack will want updating to reflect the cULus mark replacing the CSA+UL pair that comes with the SCU21.
