Trying to add a new PLC device

I'm trying to add an AB micrologix 1500 PLC, the only selection is 1000 to 1400 for the micrologix. I've tried all the AB drivers with no luck. Could sure use a suggestion or 2. Thanks

MLX 1200 and 1500 are only partially supported. You should be able to connect and manually address tags, but browsing doesn't work.

Using the micrologix driver? I keep getting "Determining Protocol" message but no connection.

Yep. Maybe there's a connection path you need? Try 1,0 even just to force it into bridged EIP mode.

edit: oh, also try the "disable processor browse" setting.

Tried both suggestions, still getting the same message. "Determining Protocol"
