Critical Equipment Monitoring System

GI provided a detailed design for a Critical Equipment Monitoring System (CEMS) for a biotech research and development facility. The system was required for compliance with Good Laboratory Practices (GLP) directives. The system monitors temperature for various freezers, refrigerators, and incubators, and also to monitor carbon dioxide levels in incubators. The equipment to be monitored was distributed in various areas through the facility. The design included an Allen-Bradley ControlLogix system with I/O racks connected via existing Ethernet fiber optics.

The ControlLogix interfaces with a Pi historian via OPC, and the Building Automation System (BAS) via Modbus. Local PanelView operator terminals were included in order to provide an interface for calibration. The project included meetings with various personnel including lab scientists, technicians, engineers, network administrators, and validation specialists. A high-level system architecture drawing was developed to be able to effectively explain the system design to all parties. Additional
documentation included a Requirements and Design document and a System Description.
