Can one Cmore panel be used to control 2 plc's?
« on: July 14, 2009, 09:05:28 AM »
Is it possible to use one Cmore touch panel to control 2 seperate plcs?  I am setting up one system to control a bulk silo operation and one to control a blender but want to operate both systems from one touch panel.

I don't know about C-More specifically, but in general this is a capability of many MMI's.  First you'll need one that allows for multiple PLC's in the tag database format, and also one which either has two ports with which to talk to the PLC's or an RS485 capable port, or many of the newer MMI's have ethernet.  The PLC's hopefully have ethernet or 485 as well (AD's do) or you should be able put a little 485<->232 converter in front of each PLC.
I retract my earlier statement that half of all politicians are crooks.  Half of all politicians are NOT crooks.  There.

Yes you can. I added DEVxxx for each plc. I gave each an IP address. I can look and control several plcs from where I am. Now Allen-Bradley has features where you can load several completely programs. You simply load the program you want and run that plc. But of course that will cost you some bucks. The c-more does not allow you to store and load different programs, but you can do it with different screens. Just make sure you link tags to the proper DEVxxx. Try it.
