Summary

This paper deals with the conversion of an existing batch plant control system to a PLC-based system, without interrupting glass production. The Vetrotex Certain Teed plant at Wichita Falls, TX, manufactures continuous filament fiberglass, and the batch plant provides mixed batch for multiple furnaces, three of which were active at the time of this project. The plant is approximately 15 years old. Vetrotex Certain Teed found it difficult to maintain the computer and electronic scale portions of the batch plant control system. Also, the plant had been expanded significantly over its 15-year history, and the batch plant control system had to expand accordingly. These factors made it difficult to maintain the control system and keep the batch plant operational. In addition to the conversion to a PLC-based control system while maintaining operation, this paper describes additional benefits resulting from the modernization.
