Case Study: APACS DCS Migration to Siemens PCS 7

Case Study: APACS DCS Migration to Siemens PCS 7

Josh Dalzell | November 30th, 2018

An industrial utility service company in Kentucky needed to upgrade and migrate its distributed control system (DCS), which came with a few challenges.

DTE Calvert City (DTECC) made the decision three years ago to upgrade their obsolete Process Suite HMI to APACS OS. For 15 years, APACS DCS had been a reliable and comfortable system that was used to maintain the operational functionality for a plant that generated power and utilities around the clock. However, now the APACS hardware lifespan was coming to an end due to a decrease in both new and used replacement components and an end to the support for the human-machine interface (HMI) and APACS hardware.

Cross Company, a certified PCS7 Solution Partner for Siemens, had built trust with DTECC by implementing the smooth transition to APACS OS. DTECC reviewed their needs, concerns, and questions and chose Cross Company to migrate their APACS DCS to a full Siemens PCS 7 system implementation.
