I'm new here, so I hope I'm posting correctly. I'm using a Panelview Plus 1000 as an interface for two different systems (i.e. two ControLogix controllers). Is there any way I can write the active display number to BOTH controllers, and remotely change the display from BOTH controllers? I'm using Ethernet communication, and the only way I see it possible, is to assign tags to one controller, and use produced/consumed tags to send the information to the other controller. However, this will not work for me as the system may be run periodically with one controller powered off. Any suggestions?
