In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. At least one data field to be filled with transmission data is clearly assigned to each further station. The data frame is transmitted as an outgoing data frame from one station to the next, with every further station filling the respectively assigned data field with transmission data. The last station returns the data frame as a returning data frame to the series of stations. The stations read extraneous transmission data from the data fields in the returning data frame. Preferably, the respective data fields are individually assigned to the stations.
A method for transmitting data in a control system comprising a plurality of spatially distributed stations which are connected to one another via a communication medium, the stations comprising at least one control unit for processing state data captured by sensors and for generating control data for operating actuators and comprising a plurality of I/O units connected to said sensors and actuators, the stations being logically arranged in a series which defines a first station, at least one second station and a last station, the method of performing peer-to-peer communication between all stations in said series of stations within a single communication cycle defined from the start of an outgoing data frame from the first station and the receipt by the first station of a returning data frame, comprising the following steps:
A control system for the automated control of installations or appliances, comprising a plurality of spatially distributed stations connected to one another via a communication medium, said stations comprising at least one control unit for processing state data captured by sensors and for generating control data for operating actuators and comprising a plurality of I/O units connected to said sensors and actuators, where the stations are logically arranged in a series which defines a first station, at least one second station and a last station, the control system being configured to perform peer-to-peer communication between all stations in said series of stations within a single communication cycle defined from the start of an outgoing data frame from the first station and the receipt by the first station of a returning data frame,
A communication module comprising an application-specific integrated circuit or a programmable hardware platform for use in a station of a control system comprising a plurality of spatially distributed stations connected to one another via a communication medium, the stations comprising at least one control unit for processing state data captured by sensors and for generating control data for operating actuators and comprising a plurality of I/O units connected to said sensors and actuators, where the stations are logically arranged in a series which defines a first station, at least one second station and a last station, the control system being configured to perform peer-to-peer communication between all stations in said series of stations within a single communication cycle defined from the start of an outgoing data frame from the first station and the receipt by the first station of a returning data frame,
