The helium cryogenic system in NSRRC is a fully automatic system using the Siemens SIMATIC 300 PLC (Programable Logic Controller). Modularization in both hardware and software makes it easy in the program reading, the system modification and the problem debug. Based on the LabVIEW program we had developed a supervision system taking advantage of the Internet technology to get system's real-time information in any office. The functions of this supervision system include the real-time data

The data is accessed via a Profibus line connecting the PLC system and the supervision system with a maximum baud rate 1.5 Mbit/s. Using this supervision system makes it easy to master the status of the cryogenic system within a short time and diagnose the problem.
