text: <s>[INST] Cannot connect to 1756-L71 We have a setup which consist of 11 drives on DLR connected to EN2TR controlled by L71(V20) . Everything works fine but as soon as all the drives are switched OFF i am not able to connect to the controller and the controller basically hangs up .. i can see the chassis in rslinx but when i browse the chassis and try to connect to processor it does not connect and wait a very long time .. Also changing key switch from run to program also doesnt help . The programming device is also connected in the same DLR .. basically the setup is EN2TR to ETAP .. ETAP to drive 1.. drive11 -- EN2TR in DLR and i am connected to device port of ETAP .. As mentioned above i can see the chassis in rslinx but when i browse and try to connect it in logix i cant Any suggestion on what could be cause ??? [/INST] Which device is the DLR supervisor, the PLC or the ETAP? Have you tried opening the ring between the EN2TR and drive 11 so that the setup is a line, and then shutting down the drives? \\n </s>
