Is there a driver that will allow me to talk to a Controllogix PLC through an ethernet card, and communicate with devices connected to that Plc through a Control net bridge card?

I want to read and write various tag names, memory tables, from the Controllogics PLC and from the various devices connected to it via device net bridge card.

For most PLCs, National Instruments has the ability to communicate using the Lookout Protocol drivers. Although the Lookout Protocol drivers do support AB products, the ethernet version of the Controllogix is not currently supported. There is an ethernet solution for the PLC5 family and a serial solution for the Logix family but there is not ethernet solution for the Controllogix.

To expand a little on what Hokie said. We do support most Allen Bradley plc's (including much of the Logix family).

To be more specific, we have objects supporting the micrologix plc's. We do not, however, currently have objects that support the controllogix plc's. For a more detailed list, pleas refer to:Lookout Protocol Drivers
