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.
