ABSTRACT:
An automatic system for sequentially controlling and monitoring for detecting at least two discrete devices used by a batch process. To accomplish this a plurality of device driver blocks are connected on a one to one basis with a plurality of discrete devices. Each driver block receives signals from the discrete device as to its status and sends a control signal to the device to indicate the operation of same. The device driver blocks are monitored by a monitoring function block which establishes status signals to a sequence controller which in turns controls the individual device driver blocks according to the requirements of the batch process.
