Answer question
800xA 5.1 revC FP4 upgrade issues
We have an already commission powerplant with 800xA 5.1 revC installed. The Control application is build with Function Designer. Due to some contractual and technical issues we would need to install FP4. However, when testing to upgrade the project in a test enviroment we get errors. In one application out of appr 40 we alredy get 159 errors! To adress all these errors we would need weeks and might also be forced to comission the application again. Are there any workaround available since this is already a comissioned plant?
Among the errors we have seen are:
-There is no forward flow between the blocks of the feedback connection"
-Instance specific Initvals for CM only allowed for ports which have "default" Value as "InitvalOfObjectType"
-Multiple connections are not allowed in both source and destination"
The last one is adressed in system 800xA 6.0
