Environmental Monitoring System
QSPEC Solutions’ client is a confidential life sciences manufacturer. The purpose of the Environmental Monitoring System is to provide regulatory required monitoring of the air quality (differential pressures and particulate counts) in the production areas of the pharmaceutical plant. This project involved replacing the existing overloaded and unreliable Opto-22/PC based system with a PLC based SCADA system. QSPEC Solutions’ system monitors the various differential pressure sensors and particulate counters located in two separate production areas in multiple ControlLogix PLCs. The interface to the particulate counters required development of a custom program for a ProSoft serial card in the PLC, which provides direct access to the particulate data in its most accurate form.
