Abstract
A manufacturing facility includes a plurality of programmable logic controllers that contain operating programs and process parameters. The programmable logic controllers are connected to a network such that the operating programs and process parameters from the programmable logic controllers can be backed-up to a remote data storage device. Preferably, the backing-up of the programmable logic controllers takes place automatically and periodically in a manner that does not interrupt the manufacturing process.
Claims6
A method for storing manufacturing process parameters, comprising the steps of:
- providing a plurality of programmable logic controllers that are operable to control a manufacturing process, said programmable logic controllers having programs and operating parameters stored therein, wherein said programs contain instructions for controlling the manufacturing process;
- connecting each of said plurality of programmable logic controllers to a network;
- and,
- using said network to back-up the programs and operating parameters from the programmable logic controllers to a remote data storage device.
