800xA Error opening Generic Control Network Configuration
800xA v5.1 rev. E.
At some moment I've discovered that access to "Control Structure-RSO5, SoftPoint Generic Control Network-Generic Control Network Configuration" gives an error.
Recreation of object, delete & add, renaming, adding new one show the same effect.
Screenshot and "Collect Basic Data for Troubleshooting" attached.
Don't want to waste time reinstalling all the software - could this be project's problem?
I've tried reinstallation in different combinations.
Finally problem appears after installing Feature Pack 4 (rev. E) even without my project to be restored just with default minimum system configuration.
Modbus & OPC communications are availiable.
I'm not advanced enough to understand what potential problems will inaccessibility of Generic Control Network Configuration bring me in future if I leave everything as is. Could someone spectare consequences?
