Description: This paper demonstrates how modern database tools can be used to greatly improve the productivity of tasks on a control system. The example involves a DuPont facility in which a very large Honeywell TDC 3000 control system was converted from older to newer vintage of field network and control devices. This involved translation of control algorithms, IO assignments, HMI, system configuration, and other critical data.

Description: This paper addresses the benefits and shortcomings of control system applications based on OPC. A case study at Austin Energy’s Decker Power Plant provides the basis for the presentation. It is found that OPC provides great benefit, but the implementation of this standard in the industry is severely lacking in diagnostics to help the end user when problems arise.
