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.

Abstract: An automatic system for the control and fault detection of discrete devices used by a batch process which eliminates extensive function block configurations and system loading in process control systems by providing an assembly to monitor the discrete devices and means to match the monitoring assembly to the discrete devices and controlling the monitoring assembly.
