Abstract

The present invention relates to a processing module for a modular automation system, for instance a modular stored-programmable control, in which the automation system includes a central unit and peripheral units such as input/output modules, subordinate to the central unit. The peripheral units can be coupled to each other via a device bus. A processing module comprises a processor, a memory, a blockable bus coupling element which can be coupled to the device bus, and a blockable central unit coupling element which can be coupled to the central unit, all of which are connected to each other via a module bus that is internal in the processing module. The processing module has a communication interface which is connected with the processor. In this way the central unit can be relieved to a considerable extent of communication activity.
