AB PLC-3 Communication with DH+

[jcengtips]

Does anyone know if newer AB products can address the PLC-3 addresses over DH+, such as a ControLogix DHRIO card? Can RSLinx be configured to read or write to the old PLC-3 addresses?

Yes use a 1785-ka comms adaptor module. go to ab.com and search for the above - download the file. you should be able to directly access the plc3, though i think the node addresses are different when looking through the adaptor if i remember correctly. The manual should tell you.
