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

A communication system of an industrial automation system comprising:

• a central processing unit;
• a module to expand the central processing unit;
• a serially point-to-point connection to transfer data between the module and the central processing unit,
• a physical layer for communication, wherein the physical layer has a configuration which is adaptable based upon parameterization in accord with one of multiple predefined fields of application of the module in the automation system so that the module can be used in multiple different topologies without requiring hardware or firmware modifications, there being a parameter for selecting a predefined field which is used to configure the module in accord with a selected field of application, and wherein the module has:
• at least two transmitter for the physical layer, and
• at least two receiver for the physical layer, and ports,
• wherein, based on at least one parameter, a configuration file of the physical layer is applied to provide a daisy chain layout, and wherein an incoming telegram at a first port is received in a first receive buffer and re-sent at a second port,
• wherein a predefined field of application is selected via the parameter, the parameter being used to configure the module in according with the selected field of application, and wherein the data transfer between the central processing unit and the module is optimized for the selected field of application by the parameterization of the module.”
