註釋

A gap exists between process control and management information systems (MIS). The gap is formed by philosophies, vendors, marketing strategies, programming languages, and communication protocols. This paper describes a system that traces ingots in the hot line department of a rolling mill, and bridges the gap between MIS and process control. Communications with MIS use a vendor-specific synchronous protocol, while communications with process control systems use a start-stop protocol that was developed in-house.
