I have been trying to write a numerical value from an Allen Bradley Micro-1400 into the registry table within the Productivity series P2-550 via Ethernet IP messaging and have had no success. I am starting to believe it is within the Allen Bradley side which I do not have the Class/Instance/Attribute values correct. Wondering if anyone has been successful in being able to communicate to a micrologix-1400?

Yes, I got this to work using the help file of the Productivity Series. Just checked and it is topic P259 in that help file. It is not 'exactly ' the same but very close. The images they have in the help file is from Studio or RSLogix 5000 but it is very close to what it is in RS Logix 500. You just match up the Class (it is always 4), Instance and Attribute (always 3). The sizes need to match exactly as well. I just mapped over from an N file. Note that it is Bytes in the MSG instruction. Make sure you match the "Message Size (bytes): " value from the Productivity Series setup.
