Communication variables between Applications in same controller (AC800M)
I would like to use communication variables between Applications (Application_1 and Application_2) within the same project and same controller.
Should the communication variable (e.g. "MyVar") be defined both as an "in" parameter in Application_1 and an "out" parameter in Application_2?
Or should the parameter be declared in one of the Applications (e.g. Application_1) and then addressed to as for example "Application_1.Diagram1.MyVar" when used in Application_2?
Is there something else that is needed for communicating the variable between Applications?
Thanks in advance
