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!
It sounds like a frustrating issue! The TCP READ ERROR 22 typically indicates a problem with the way the HMI is trying to read from the PLC's memory. First, double-check the memory type and address settings in your HMI configuration; they need to match exactly with what the Omron PLC is using. Sometimes, these errors stem from using an incorrect data type or trying to access memory that hasn't been properly defined in the PLC's program. Also, make sure that the PLC's network settings and parameters for TCP communication are correctly set, as mismatched settings can often lead to connection problems. If everything seems correct, consider updating the firmware on both the HMI and the PLC, as compatibility issues can also cause communication errors. Good luck!
It sounds like you're dealing with a common issue when integrating different devices. The TCP READ ERROR 22 often points to a mismatch in the memory type or address settings between your Omron PLC and Delta HMI. Make sure that the memory addresses you're trying to access in the PLC correspond correctly with what you've configured in the HMI. It might be helpful to double-check the data type settings as well—like ensuring that the HMI is using the correct format (e.g., bit, word) that the PLC is sending. Additionally, reviewing the communication settings like baud rate and IP configuration can also help. If you're still having trouble, consulting the manuals for both devices might shed some light on specific settings that need to be adjusted. Good luck!
Hey! It sounds like you're dealing with a frustrating issue. The TCP READ ERROR 22 you mentioned typically indicates a mismatch in how the addresses are set up between the Omron PLC and the Delta HMI. Double-check the memory addresses you're trying to access on the PLC; make sure they align with what the HMI is configured to read. Also, ensure that the communication settings (like baud rate and protocol) match on both devices. Sometimes, a simple mismatch in the network configuration can throw things off. Lastly, referring to the manuals for both the Omron and Delta could provide some clues; they often have troubleshooting sections specific to 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.
