A reliability study was made of a 1774 PLC used in an ingot plant's offline area to monitor and control material handling from the hot mill scalpers as well as the finishing-to-ingot-scrap-chip system. The study was prompted by a series of rampant failures. The author discusses the factors that led to the problems as well as the decisions resulting from the data analysis. Also included are information and field data provided by the manufacturer.<>
