Method and system for the homogeneous integration of programmable logic controllers in a plant model

摘要

The invention comprises a solution for the efficient incorporation of programmable logic controllers (plc, sps1) in systems model supported descriptions of automation systems. By avoiding information breaks along the path of the plants simulation of the sps - project planning to the result of use in client - applications are continuous data streams is achieved. As a uniform and centrally addressable resource information can be directly plcs, and their role in a plant, and thus downstream applications of the direct context with respect to the plants model providing. In the case of simultaneous saving of data volume in the plc, defects in the exchange of information at the animal is avoided as well as the access permits only to authorized operators.
