We have a MicroLogix 1500 talking to an 1761-NET-ENI module. From the module, the Ethernet plugs into a switch along with a PanelView 550. The module had appeared to fail again (about the 4th time since I started my position a little over a year ago.) Every time it fails, we get a read timeout error on the PanelView 550. I configured it the same way I have all of the others. I used the ENI utility and then I swapped it out.
From the Ethernet switch, I can ping both the ENI and the PanelView. In RSLinx, I can talk to the PLC by directly plugging into the serial port. However, it appears that the PLC will not talk to the ENI. I swapped the cable out and still no results. Anybody have any ideas?
