Replacement & Compatibility FAQ
Q: Can CJ1M-CPU12 directly replace CJ1M-CPU13?
A: Yes. Both share the same 10K step capacity and CJ-series backplane interface. Program migration is straightforward via CX-Programmer.
Q: Is CJ2M-CPU11 backward compatible with CJ1M systems?
A: The CJ2M series uses the same CJ-series backplane, so most I/O units are compatible. However, some CJ1-specific instructions may require revision in CX-Programmer.
Q: Can I expand I/O beyond 640 points on the CJ1M-CPU13?
A: No. The CJ1M-CPU13 supports a maximum of 640 I/O points. For larger systems, consider upgrading to CJ2H-CPU64 or higher.
Q: Does Konmask.com offer programming or integration support?
A: We specialize in hardware supply. For programming support, we can refer you to certified OMRON system integrators in your region.
Q: What is the lead time for CJ1M-CPU13?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks depending on sourcing.
