Application-Specific FAQ
Q: Can the CJ1G-CPU43H communicate with OMRON HMI panels (NS series)?
A: Yes. Via the built-in RS-232C port or an EtherNet/IP unit (CJ1W-ETN21), the CPU43H connects natively to NS5, NS8, NS10, and NS12 HMI terminals using OMRON’s FINS/Host Link protocol.
Q: Is this CPU compatible with CJ2 expansion units?
A: No. CJ1G and CJ2 series use the same physical bus form factor but are not cross-compatible at the firmware/software level. Ensure all I/O units are CJ1-series rated.
Q: What is the maximum program size for the CPU43H vs CPU44H?
A: CPU43H supports 30K steps; CPU44H supports 60K steps. For programs exceeding 30K steps, specify the CPU44H (CJ1G-CPU44H).
Q: Can this unit be used as a replacement for a CJ1M-CPU13?
A: The CJ1G-CPU43H offers a larger program capacity and more I/O than the CJ1M series. Program migration via CX-Programmer is straightforward, but verify I/O unit compatibility before substitution.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 12-month functional warranty on all verified units. Contact us for warranty claim procedures.
