PCS7 Control System Upgrade alongside Mechatherm
Mechatherm’s end-user was looking to upgrade their PCS7 control system for their two combined heat and power plants and associated gas compressors.
The project involved; – Integrating a new redundant server pair to support site risk management. – Replacing the obsolete control system CPU with a new S7 – 410H – Safety functions to be implemented using standard I/O and PCS7 safety matrix – Control functions to incorporate advanced process logic (APL) software libraries – Profibus interface to Honeywell Kromschroder burner management systems
The addition of a new safety matrix and APL libraries functionalities was made possible by rewriting the software rather than a straightforward migration.
