On the factory floor level where several controllers are presented there is a task of unification of controllers into a single system. The important feature of this architecture is the fact that the network gateway in FNC is entirely transparent for modules. Using standard local network for unification of intellectual modules inside FNC and full exception of traditional parallel buses as an inter-modular communication mean allows to solve without additional efforts a number of problems which are unsolvable for controllers with traditional architecture. Transferred data in local networks are protected by cyclic control sums. Such protection of data against distortions is not available for majority of parallel buses.
Some networks have no physical addresses i.e. all messages have their own type or class identifiers.
This allows to design dynamic patterns of system information flow routing. Moreover, there are special system and broadcast messages allowing to realize a number of necessary system functions e.g. time synchronization and other functions requiring synchronous processing. In multiple-processor parallel architectures conversely centralized arbitration scheme is used. An information element in networks is a package-form message. A package is a normal transaction, its integrity is traced on the network level.
