Try disconnecting your PanelView and then run RSLinx to connect to the PLC using the 1747-PIC/AIC+ driver. Note that when the PIC driver loads in a WIN-XP system, you will get a warning message about incompatibiliity. Just ignore it, click "Continue Anyway" and you should be OK.
I have never been able to connect a laptop to my PLC through the AIC+ when a PanelView or PanelView Plus is connected to the DH-485 network, even using the 1747-PIC/AIC+ driver. I'm not certain if the PanelViews lock up the token too long or what, but I have to un-plug the PanelViews in order to "see" the PLCs, and I have to connect to the PanelView programming port directly to download from PanelBuilder, even if I'm using RSLinx for the download.
Needless to say, this is very, VERY irritating. I have talked to my distributor's tech support about this, and they seem to accept it as just a fact of life in the A-B world.
Come on, Rockwell Software guys, can't you fix this?
