摘要:
A communication network for programmable logic controllers (PLCs) wherein selected memory means (16) of each PLC have at least two ports directly accessible by other PLCs and certain registers of the PLCs are identical to enable efficient, high-speed transfer (30) of block of data between the PLCs.

摘要:
The invention relates to a device which has a flexible communication and control structure and is coupled to other devices or a higher-order control unit of an automation system via a serial data bus (FES). The inventive device comprises at least two or several communication interfaces (KS) and at least one stored-program controller (SPS) such that the stored-program controller (SPS) is configured as a replaceable unit while data is transmitted between the communication interfaces (KS) in an entirely transparent fashion and/or is further processed via the internal stored-program controller (SPS).
摘要:
The present invention relates to the provision of a modular control system for a glass forming machine. The glass forming machine control system comprises one central control unit (20) and one machine control unit (22), which are connected via a high-speed data bus (32). The machine control unit (22) is spread out to a plurality of peripheral control units (24, ..., 30) via a plurality of high-speed data buses (34, ..., 40). The machine control unit (22) is adapted to distribute control signals received from the central control unit (20) to the peripheral control units (24, ..., 30) in real time.
