I have the following Items connected for DH-485 per the drawing.
SLC 5/03
HMI: Automation Direct EA9-T10CL+13Y19B054
1747-AIC #1: connected directly to the SLC via 1747-C11 cable
1747-AIC #2: connected to 1747- AIC#1 via shielded cable
I can connect my laptop and communicate online with the SLC (via RJ-45 ports) from either of the 1747-AIC's with no issues.
If my laptop is connected to 1747-AIC #2 and online with the SLC and I attempt to plug the HMI RJ-45 cable into 1747-AIC #1, the HMI begins communicating online with the SLC, but severs my laptop connection with the SLC.
With my laptop disconnected from the AIC's, the HMI will operate when connected to 1747-AIC #1, but when the HMI is connected to 1747-AIC #2 it will not connect to the SLC.
SLC Channel 1: Node 1
C-More: Station: 1 Panel Station: 8
I've attempted to change the station number in RSLinx from 00 through 10 with the HMI still connected to 1747-AIC #2 and my laptop connected to 1747-AIC #1, but I get nothing.
Any suggestions of why there is a communications problem? Settings suggestions?
