Communication variables between Applications in same controller not resolved on Simulator 800xA
Hi, we have a controller with 2 different applications, so we share these variables using Communications variables (MMS IAC). According to manual, if the OUT and IN communications variables are set in "Auto" the IP address should be resolved automatically just downloading the program to the controller, nevertheless this is not working on the 800xA Simulator platform but it's working in the production 800xA system even when both systems have the same configuration and logic's. To solve this issue we are setting the IP for the Communication variable IN, doing this we get communication between applications, however we most fix it since every time someone make a full download on 800xA production system to restore it into the Simulator to update it, they would have to set all the IP's for the communications variables IN, which is not acceptable.
Has someone experienced this?, there is a fix or configuration we are missing?
My experience shows that for IN IAC variables you should define IP address. I think that is described in the help: "Applicable only to communication input variables. It is only valid on the client-side as long as the communication variable is not bi-directional. This field defines the IP address of the controller that contains the corresponding communication output variable (with the same name) in any of its applications."
