I am currently using an L553 processor to communicate with an L552 processor via Ethernet. About a month ago, I set up a new MSG instruction on the L553 to retrieve data from the L552. While the system generally operates smoothly and facilitates data transfer, I've encountered a recurring issue where the instruction fails several times a week, resulting in an error. The Ethernet error code I'm receiving is "0xD1 - An invalid Internet address or host name was entered." To resolve this fault, I simply disable and then re-enable the rung, which temporarily restores functionality for a few days. Recently, I discovered that entering the rung in edit mode, running a test, and then appending it also resolves the issue. Despite searching the Allen-Bradley knowledge base, I haven't found any information addressing this specific problem. Has anyone else experienced a similar issue or have suggestions for a solution?
Perform a cross-reference analysis on the 51-word message control block to ensure that no data is being written to it, which could potentially corrupt the message configuration. Additionally, check if the controller is equipped with a Human-Machine Interface (HMI) or if there are any other components experiencing communication issues. I suspect there might be a new device on the network that shares a duplicate IP address.
An HMI is successfully connected to the processor on the same Ethernet network without any reported issues. I suspect the problem might be tied to the L552, as the other messages in the L553 program are functioning without errors. Additionally, there's an HMI linked to the L552 that is operating smoothly, showing no signs of trouble.
