Communication Variables between multiple Soft Controllers
I have a control builder project with 9 controllers, I have the applications downloaded to the soft controllers and everything is fine except the communication variables, it doesn't seem that the controllers are reading from each others and I have and Error on the IAC MMS protocol does it have anything to do with the communication between the controllers? Is there any special configuration that I should do to enable the controllers to communicate between each other?
The OPC Server is working fine and I can see that the graphic displays can see the tags on the controllers and I tried to force a variable from one controller ,but the forced value didn't appear on the controller which reads this tag.
Please check the pictures below
Set an IP address of your virtual system to the each CPU System identity , plus add a colon and id number of your softcontroller , e.g. 172.16.84.1:2 . (right click on CPU, Properties->System identity)
Set the same IP address without colon to the firrst Ethernet channel of CPU. Disable secondary Ethernet channel.
Check if all communication variables in all POUs have IP address assigned to Auto.
