FAQ

Can I swap a CJ2M-CPU31 for CJ2M-CPU32/35?

I/O and memory differ by model — match the CPU to your project memory requirement; send your current MPN and we confirm.

Does the CPU ship with a program?

No — it ships blank. We can pre-load your CX-Programmer project on request.

Is the CJ2M family still current?

Yes — CJ2M remains an active Omron family, so both new and tested surplus are available.

How do I know if my surplus CPU is genuine?

Every unit is visually verified for Omron labeling and tested for boot + comms where possible.
