I have a new AB Micro820 that I am trying to configure. I cannot communicate with it. I have tried directly over ethernet, and through a network switch. I have tried with my serial port (all of that following the directions at http://www.mikeburdis.com/wp/notes/getting-started-with-the-allen-bradley-micro820-plc/ ). I know my serial port is good because I can bridge the Rx and Tx and get data through a terminal. When I have it connected via a ethernet switch, I am getting a light indicating a repeating network collision from the port that the PLC is connected to. I have tried looking for any communication using wireshark, but I don't see anything.
I also tried putting the information on an SD card, with ConfigMeFirst.txt in the root directory, using the following code:
[PM]
[CF]
[RSPD]
[IPA=10.0.2.20]
[SNM=255.255.255.0]
[GWA=10.0.2.4]
[END]
Nothing is working. I am getting flashing green lights on Run and Comm and a flashing red on Fault. Is there something wrong with the PLC, or am I doing something wrong?
