AC110 FCB Version Mismatch
I've recently upgraded an old 800xA system to the latest version. The system except for an AC800M controller uses also a few AC110 controllers. When I try to open a node's application using APB 4.3/0 Ι get a warning about the difference between the current version (FCB 6.4/0) and the version used to create the function chart (6.2/1). If I choose to initialize the node data I cannot change the application because the 'On-line Preparation Mode' is disabled. If I choose not to initialize the node data I can change the application because the 'On-line Preparation Mode' is enabled but I get a warning saying that I may work with incompatible data. Is that dangerous? How can I initialize the node data and still be able to change the application?
