If the Allen Bradley PLC 1769-L32E also supports TCP or UDP you will be able to exchange data between those CPs. Kind regards

The problem is that S7 speaks S7 protocol and the AB speaks CIP protocol. They cannot understand each other even if they are both on ethernet. Your options are: - Use a PC with OPC Server and OPC Client software as a go-between. But a PC is obviously not as reliable as PLCs are. - Use Profibus in stead of Ethernet.Hilscher has Profibus modules for the AB Compactlogix range. It will be cheaper than having to get a PC + software, and more reliable. Here's a link: http://www.hilscher.com/files_datasheets/D_43c23ec9e5c66_uk.pdf
