Dear Fellows... A quick question or I should say a verification of what I want to do and think will work but want to verify. I am using Controllogix PLC with two Ethernet cards. I want to go from one card and look at I/o points and checkout PLC program functionality using RSLogix5000 and from the other card I want to go via my SCADA MMI and do the same. I want to do both at the same time so that I can confirm that what I am seeing on my SCADA screens is really valid because I should be seeing the same thing via RSLogix5000. My concern is that I will have two communication sessions (both via AB RSLinx) established with the same PLC at the same time and it may not work. Any comments will be appreciated.
