RSLinx to Mitsubishi PLC A via Ethernet

I have a lab set up to attempt reading from a Mitsubishi PLC A3A with a AJ71E71N-T Ethernet Module. I am using Rockwell's RSLinx OPC server. I can see the device IP Address but can not communicate with it. Has any one done this successfully?

Is the device using PCCC or CIP based ethernet? If CIP (or ethernet/IP), make sure you are using the Ethernet/IP driver in RSLinx. If it is PCCC, use the Ethernet deivices driver (AB_ETH-1). I don't know if this is compatible with RSLinx; you may need to get an EDS file from the manufacturer. If none of htis works, you may need KEPWare OPC instead of RSLinx; it has the Mitsubishi A/Q series TCP/IP driver.
