I had this problem a few weeks back and I had been out of the office but now I am back and hoping to get a solution. I have a Compact Logix PLC on our PLC trainer. The PLC is a 1769-L16ER-BB1B Series B controller. When I try and connect to it on the ethernet port using RSLinx Classic I see a yellow question mark with a red X through it. I am in the past I would right click on the question mark and install the new EDS file but when I click on it I do not get that option. I am assuming I am missing the EDS file for this PLC. Is there a way I can find out exactly what EDS file I need for this controller or am I trying to connect to it incorrectly. The PLC already has an IP address assigned to it. I open the ether net driver in RSLinx and set it up for that IP address but all i get is the question mark. Any suggestions would be greatly appreciated.
