Named for the county in Kentucky where it made its home in the early 1980’s, Logan Aluminum, a joint venture between Arco Aluminum and Alcan, specializes in the production of rolled aluminum. The 1.5 billion pounds of metal that passes through this plant each year makes up about 1/3 of the rolled aluminum used by the entire US aluminum can market.
The Challenge: Update the Aging HMI System Without Affecting Production
The Logan Plant only shuts down only one day each year, and new products must be installed without risking Logan’s World- Class Production and Utilization numbers. Like many factories, Logan was using PCs throughout to monitor and control pro- duction, but the management team was becoming tired of system updates and ongoing PC maintenance. Whatever HMI they settled on, they wanted a way to dis- tribute the user interface without relying on the traditional distributed PC model.
