I'm sorry this is probably a simple ans. but I'm just getting into this so I'm a little bit on the igonorant side. I have the card installed with the driver and also all the above software is installed. Now the problem is that RSLINX (windows based) seems to identify the card fine. But as soon as i interface with the PLC through PLC-5 6200 software DOS BASED) RSlinx says that there are two nodes using the same position. Now if anyone can help me find out if this setup is possible or how to resolve this. I would be very grateful.
