Hello, I am currently working with an Omron CJ2M PLC and I am having trouble establishing communication with a Delta HMI (DOP110-WS). The issue I am encountering involves errors displayed on the HMI, specifically a TCP READ ERROR 22 related to 'memory type' and 'address'. Does anyone have insight on how to resolve this error and successfully connect the PLC and HMI?
If you're unfamiliar with the Delta HMI, communication via serial (RS232C) requires the use of the Host Link protocol. For communication via Ethernet, the FINS protocol should be used. If the Delta HMI supports Omron, it should come equipped with the necessary drivers for these protocols.
I've encountered similar problems before with my Omron PLC and Delta HMI. The error you're encountering, TCP READ ERROR 22, is usually linked to incorrect settings in your communication parameters. Frequently, this happens if there's a mismatch between the memory location in your PLC program and the HMI. Double-check that the addresses you're trying to communicate between in your PLC and HMI match perfectly. If that doesn't resolve the issue, you might want to consider checking if your PLC and HMI are using the same data format. Proper synchronization of these parameters usually resolves the error. If the problem persists, perhaps try to update the firmware of the HMI, sometimes it can resolve such communication errors. Hope that helps!

Answer: Answer: The TCP READ ERROR 22 typically indicates an issue with memory type and address configuration in the communication setup between the Omron CJ2M PLC and Delta HMI.
Answer: Answer: To resolve the TCP READ ERROR 22, verify the memory type and address settings in both the PLC and HMI configurations. Ensure that the data exchange settings, such as data addresses and formats, are correctly configured in both devices for seamless communication.
Answer: Answer: Yes, check the communication settings, network configurations, memory mapping, and data formats in both the Omron CJ2M PLC and Delta HMI to ensure they are compatible and correctly set up for communication. Make sure that the memory types and addresses used in the devices match and are configured accurately to avoid communication errors.
