Communication system for flexible use in different application scenarios in automation technology

Abstract

There is described a module for expanding a central module of an automation system, the data transfer between module and central module being accomplished by means of a serial communication system having point-to-point connections in a daisychain or backplane layout and the module having, in a physical layer herefor, at least two transmitters and at least two receivers. There is also described a communication system having at least one module of said kind and a central module. A module for a communication system within an automation system is specified, which module can be flexibly and easily adapted to the respective field of application. There is further described a flexible and scalable communication system for the data transfer between a central module/a CPU and at least one module with the aim of realizing a modular expansion of the central module/CPU. A physical layer can be parameterized in order to adapt it to a predefinable field of application of the module, in particular in terms of speed, availability and/or expandability.
