Versioning
Corresponding to the general conditions given by the PLC run time system and the requirement for availability even without a development system or a running PLC application, the version information is stored on the one hand in the names of the PLC libraries and, on the other hand, function blocks are implemented that check, in the application, the versions of the individual components (PLC libraries and HLI definitions at the MC or PLC end) of the ISG-MCP.
