Thanks PMCR

I should be able to work with bits in the N file. This seems complicated (for me too) though. My preference would be to probably use CompactLogix as a gateway and then use implicit message between the Omron and the CompactLogix.  Do you have any writeup on the implicit message between CompactLogix and CJ1? I will do some research into this option. Thanks.

PMCR, the document indicates that data files must be created in the SLC500 controller as N20:0 - N20:49, F21:0 - F21:49, N22:0 - N22:49 & F23:0 - F23:49. What do I do, if these data files are already being used for something else? Also, how do I read binary data? Thanks.

Thanks for the suggestion BITS N BYTES . I'll look into that protocol converter as well.

Thanks for your response PMCR. I will download the code, test it and let you know the results. I think B, I & F is all I need. I'm only interested in reading the machine fault code and not the PLC system faults. Thanks again!

Hi kaiser_will. I know this is a very old post, however did you ever get this to work? I'm trying to read data from a Allen Bradley SLC 5/04 PLC into an Omron CJ1 PLC using EthernetIP, however there doesn't seem to be an easy solution. A colleague suggested using the FINS routing table, but Allen Bradley doesn't use the FINS protocol so I'm not sure if this is possible. Any suggestion will be helpful. Thanks.
