SYNCHRONOUS, CLOCKED COMMUNICATION SYSTEM WITH LOCAL INPUT/OUTPUT COMPONENTS AND METHOD FOR INTEGRATING LOCAL INPUT/OUTPUT COMPONENTS INTO SUCH A SYSTEM

摘要

The present invention relates to a synchronous, clocked communication system, for example, a distributed automation system, the subscriber can be any desired automation components and which, by means of a data network (1) are coupled to one another. By means of the disclosed process for the integration of a decentralized a - / output - assemblies (2, 3), these decentralized a - / output - assemblies (2, 3) in such a way in the synchronous, clocked communication system, to ensure that they can use without any restriction, whose properties. Thus, in particular, the detection of input signals and the output of output signals in a deterministic and synchronous manner in the decentralized a - / output - assemblies (2, 3) possible. In addition, the disclosed method, input signals with an accuracy of less than the length of a communication cycle of the communication system to detect and the switching of output signals in smaller time granularities than the length of a communication cycle, which in particular application, for example, for switching cams. In addition, because of the invention, a synchronization for actual value detection nominal value and outputs of most various automation components, such as, for example, decentralized a - / output - assemblies (2, 3) and digital drives (4, 5, 6) makes it possible to. As a data network (1) of the communication system are, in this case all possible bus systems such as, for example, field bus, profibus, ethernet, industrial ..
