Process control for viscous materials

A process controller has a processor with an activation controller, an transaction controller and a batch processor. The transaction controller operates in communication with a machine interface for controlling operations of a plant device for overall job sequencing and individual job control. There is automatic communication of various polling and return signals to ensure correct sequencing of mixing operations. The activation controller helps to ensure that the processor controller is configured at all times for correct operation at a particular materials distribution location. The activation controller 2(b) creates a control file and carries out verification operations automatically to ensure that the initially sorted data is correct. The batch processor operates with parallel control and transaction transmission files which are automatically transmitted to a host computer for consolidation. Control data in both the control and transaction transmission files ensure data integrity.
