I am trying to connect to an AB Logix5555 via 1756-ENBT ethernet device. We want to get online with the PLC to watch the inputs and outputs. So, my problem is, I just don't have any experience with this stuff, and I cannot get RSLinx to see the PLC station. The computer is Windows 7, we are plugged into the 1756 with a standard ethernet cable (as far as I know). I'm not sure, but I think the first problem might be that in RSLinx, I cannot see a driver to configure for the 1756. Also, by using I believe just a standard ethernet driver in Linx, and typing in the PLC's IP address, I was able to see the PLC, but it said "Unrecognized Device," and gave me COMM error "01E00204." If anyone has any ideas, please, let me know. We have several AB 5000 series in the plant, and have never been able to connect to any of them, as far as I know. However, our integrator comes in, and (obviously), just connects to them right away. Frustrating.
