Abstract:
A peripheral assembly system which can be arranged in a decentralized manner, the peripheral assembly system comprising a basic assembly and at least one expansion module;the basic assembly including:an intelligent unit,an expansion connection for expanding the basic assembly, the expansion connection connecting the intelligent unit to the at least one expansion module, the expansion connection having a dedicated expansion contact for each useful signal to be transmitted between the basic assembly and the at least one expansion module,a bus connection connected to the intelligent unit, the bus connection for communicating with a superordinate controller,at least one first peripheral drive unit connected to the intelligent unit, andat least one first peripheral connection associated with the at least one first peripheral drive unit for communicating, together with the at least one first peripheral drive unit, with a technical installation to be controlled;the at least one expansion module including:at least one second peripheral drive unit, the number of the at least one second peripheral drive unit being considerably fewer than the number of the at least one first peripheral drive unit,at least one second peripheral connection associated with the at least one second peripheral drive unit, andat least one plug-in location, each of the at least one plug-in location for receiving a respective one of the at least one second peripheral drive unit, and each of the at least one plug-in location having a dedicated plug contact for each useful signal to be transmitted between the basic assembly and the respective one of the at least one second peripheral drive unit, each of the at least one dedicated plug contact which is provided for the transmission of useful signals being connected and assigned to the dedicated expansion contact which is provided for the transmission of useful signals, each of the at least one plug contact being arranged in the same position at each of the at least one plug-in location,the at least one second peripheral drive unit being removable from the peripheral assembly system independently of the at least one second peripheral connection.
