Abstract
A method for controlling a plant, such as an industrial production plant with a plurality of working units, such as industrial robots or the like, using at least one programmable logic control (PLC), is characterized in that historical process data are fed into an input area of the PLC and processed by a PLC program logic. An apparatus suitable for performing the method according to the invention has a real time information server for acquiring, archiving or transferring in each case specific historical process data with respect to the plant and a data stream controller for the flexible transfer of archived process data to at least one programmable logic control PLC for controlling the plant, wherein the output data of the PLC can be fed back into the latter.
Claims30
A method for controlling an industrial production plant, having a plurality of working units with controlled plant periphery generating process data during a process run-through, using at least one programmable logic control (PLC), wherein historical process data from an actual earlier process run-through are fed into and processed by the PLC or another PLC program logic in the same way as if said process data had come directly from the plant periphery.
An apparatus for fault finding, optimization, simulation and information exchange in electronically controlled plants the apparatus comprising:
- a plurality of working units with controlled working unit periphery generating process data during a process run-through;
- a real time information server for acquiring, archiving or transferring in each case specific historical process data with respect to the plant;
- and
- a data stream controller for the flexible transfer of archived process data to at least one programmable logic control for controlling the plant to provide output data that are again feedable into the PLC or some other PLC in the same way as if said output data was process data coming directly from the working unit periphery.
