How a SC utility replaced their SCADA central without service interruption or a steep learning curve.
By Jay Nicholson and Chris Little
In 1998, the Joint Municipal Water and Sewer Commission (Lexington County, SC) adopted a SCADA system that introduced them to the benefits of using historical data to reduce costs. After several years, it was apparent that their SCADA's HMI software was difficult to modify and lacked the level of technical support they required. Also, it was becoming increasingly difficult to maintain the numerous software products required to provide critical features like alarming, reporting, and trending. In this article, Operations Manager Jay Nicholson describes how his team transitioned to a new HMI software package without interrupting service or losing features.
