Case Study: a leading paper mill achieves higher reliability and less downtime with LSI's control system modernization

Leading Paper Mill - Customer Case Study

A leading paper mill was experiencing significant unplanned downtime and safety concerns due to its obsolete Foxboro DCS, unsupported PLCs, and aging motor control centers (MCCs). They required a comprehensive modernization to improve reliability and sought the pulp and paper expertise of LSI - Logical Systems Inc to design and implement a solution.

LSI executed a multi-phase project that involved upgrading the DCS to a DeltaV system, consolidating six PLC5s into a single redundant ControlLogix system, and rewiring all controls through junction boxes. The vendor also reconfigured eleven 480V MCCs to improve safety. The results for the paper mill included a major reduction in unplanned downtime, simpler troubleshooting, higher quality product, and substantial financial payback. LSI's solution provided a more robust, easier-to-maintain control system that exceeded customer expectations.
