PC Usage In The Metal Processing Industry

Years ago, personal computers (PC) were pricey devices destined for who knows where in the process industry. Now their use runs the gamut from low end data acquisition systems to high performance windows into the process area. Their applications range from CAD, CAM, CIM, and CAE to factory floor scheduling, process planning QC, facility management, cell control, and publishing. This discussion traces the evolution of a zinc plant's control automation program beginning with a PC as an operator interface and migrating to higher level work stations. Included in this paper will be a discussion of an Open Industrial System and the role PCs have played in this facility.
