Web-based distributed System for TOF Experiment Cooling Plant Monitoring

This paper discusses the monitoring and control system for an automated cooling process. The plant is located in an experiment environment and with some distance between the principal components of the system namely the cooling station of the lead target temperature measurements and the TOF experiment control room. TOF experiment operators interact from a SCADA supervisory station through the TCP-IP Ethernet communication channel with the cooling plant. The main issue concerns the degree of automation given to the plant and the SCADA station to greatly ease the TOF control room operation. Another important issue is the real need for TOF physicists and vacuum technicians to access specific operational information in their respective process systems. In this way the availability of the Wizcon® Web-based SCADA applications, which reside on standard Windows NT Web servers, deliver real-time access and historical data to the different applications. The various authorised users can interact with their own applications from any standard Web browser.
