I am starting an upgrade process for all my SLC50* PLCs and working out the communication of my machines for the upgrade. I ran into this complication I don't understand. I have 2 machines that work together using 1 HMI. Both machines have their own PLCs. Both are running SLC5/02 to 1747-AIC link coupler then to the 2711P-RN6 interface with the DH-485 communications running parallel. I don't understand how this works, or how I might possibly upgrade the communications from 2 PLC's into 1 HMI without linking the PLC's programming first. (Also, a complication I am working on, I only have the Runtime file, not the ME file for the HMI program).
Davis Colangelo posted a topic in Allen Bradley / Rockwell Automationdetails: panelview (2711P-RDT15C) connected to "switch A" (ntron p/n: F-716TX) "processor A " (1756-L62) is connected to "switch A" "processor B" (1756-L73S) is connected to "switch B" (ntron p/n: F-716TX) "switch B" is connected to "switch A" I'm trying to use a single panelview to communicate to 2 separate PLC processors (separate chassis). When I go to add the shortcut in factory talk I find the "processor B". When I connect my laptop to "switch A" I can see every thing in RSlinxs. Any one experience this issue or know how to make this setup work? Maybe there's a switch setting that is not allowing RSlinxs enterprise in the PV to see both processors?
