DESCRIPTION:
BRIEF SUMMARY
FIELD OF IN THE INVENTION
The present invention relates to an assembly system which can be arranged in a decentralized manner, including a basic assembly and at least one expansion module.
RELATED TECHNOLOGY
DE 35 37 399 discloses a peripheral interface unit which can be arranged in a decentralized manner and which can be expanded with modules by means of further peripheral interface units. The peripheral interface unit contains an intelligent unit which communicates, via a first communication means, with a superordinate computer and, via a second communication means, with an expansion device, a downstream peripheral interface unit, and, via further communication means, with the technical installation. The respective peripheral interface units have means for a peripheral drive function.
WO 94/27196 discloses a decentralized peripheral assembly having a connection device into which conversion modules can be inserted. The connection to a superordinate controller is effected by a bus connection.
The design disclosed in this publication is still not optimal inasmuch as even minimal upgrading of the decentralized peripheral assembly requires a multiplicity of individual components.
Furthermore, peripheral assemblies are known in which conversion units and a bus connection are integrated in the connection device. However, the fact that these assemblies cannot be expanded constitutes their disadvantage.
SUMMARY OF THE INVENTION
Consequently, an object of the present invention consists in providing a peripheral assembly system capable of being arranged in a decentralized manner in which a cost-effective basic system is possible which also can be expanded in a flexible manner at a later date.
The peripheral assembly system of the present invention, which can be arranged in a decentralized manner, is distinguished in that the peripheral drive units of the expansion module can be removed from the peripheral assembly system independently of the peripheral connections of the expansion module, so that the peripheral drive units can be exchanged without it being necessary to disconnect the peripheral connections beforehand and connect them again later. So-called permanent wiring is therefore achieved. In addition, the peripheral assembly system of the present invention is distinguished in that very simply designed peripheral drive units may be placed in it, which can be inserted, without alterations, into any desired plug-in locations of the expansion device, without requiring any alterations in the expansion module or the peripheral drive units.
BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages and details emerge from the following description of an exemplary embodiment of the present invention, with reference to the Figures in which:
FIG. 1 shows a block diagram of an embodiment of the basic assembly of the present invention,
FIG. 2 shows a block diagram of an embodiment of the expansion, module of the present invention, and
FIG. 3 shows a block diagram of an embodiment of a peripheral drive unit of an expansion module of the present invention.
DETAILED DESCRIPTION
As illustrated FIG. 1, basic assembly 1 includes an intelligent unit 2. Unit 2 maybe, for example, a micro-controller. Intelligent unit 2 is connected to a field bus connection 3 for communicating with a superordinate controller. The intelligent unit can communicate with a superordinate programmable controller via field bus connection 3, for example, in accordance with the PROFIBUS protocol. As a result, intelligent unit 2 can receive data from the programmable controller or, conversely, can transmit data to said controller.
Intelligent unit 2 is also connected to peripheral drive units 4. Peripheral connections 5 are in turn connected by means of peripheral drive units 4, so that, as a result, intelligent unit 2 can receive signals from a technical installation to be controlled, or can output signals to said installation. Therefore, intelligent unit 2 can communicate also with the technical installation via peripheral drive units 4 and perip
