Product details

Communication Slot Card for CS1 PLC

The CS1W-SCB21-V1: Two RS-232C ports plug into any CS1 series CPU backplane slot for programming or connecting HMIs, barcode scanners, or third-party serial devices. Works with CX-Programmer for online edits and ladder monitoring.

Mounting & Wiring Notes

Slides into any vacant slot in a CS1 rack — no tools, no drivers. Serial pinout matches the standard Omron DTE configuration; set port parameters in the CPU's I/O table (baud, parity, stop bits). Bond the shield at the PLC end only to keep ground loops off the backplane.

Frequently asked questions

What is the closest functional second-source — CS1W-SCB41-V1?

The CS1W-SCB41-V1 is the direct sibling: same series, same form factor, but with four RS-232C ports instead of two. It fits the same slot without rewiring.

What is CS1W-SCB21-V1's series and package?

Series is CS1W; package is Bulk.

Will CS1W-SCB21-V1 drop into a panel that was specified around CS1W-SCB41-V1 without rewiring?

Yes, both cards share the same backplane connector and physical dimensions. Swap them straight in — only the port count changes. Reconfigure the I/O table if you move from four ports to two.
