Different sets of representations of function blocks of a system are configured, e.g. function blocks in a Continuous Function Chart (CFC) and objects in the WinCC visualization tool, which refer back to a common database. Information about corresponding sets of representations of the system's function blocks is converted into two, e.g. HTML, documents, each having references to the other set of representations, thereby allowing navigation from one representation to the other as well as consistent modification in a plurality of representations simultaneously.
