英文摘要	Cryogenic Plant of Variable Energy Cyclotron Centre consists of two Helium refrigerators (250W and 415W @ 4.5K), valve box with sub-cooler and associated sub systems like pure gas storage, helium purifier and impure gas recovery etc. The system also consists of 3.1K liters of liquid Nitrogen (LN2) storage and delivery system. The plant is designed to cater the cryogenic requirements of the Superconducting Cyclotron. The control system is fully automated and does not require any human intervention once it is started. EPICS (Experimental Physics and Industrial Control System) architecture has been adopted to design the Supervisory control and data acquisition (SCADA) module. The EPICS Input Output Controller (IOC) communicates with four Programmable Logic Controllers (PLCs) over Ethernet based control LAN to control/monitor 618 numbers of field Inputs/ Outputs(I/O). The plant is running very reliably round the clock, however, the historical data trending of important parameters during plant operation has been integrated to the system for plant maintenance and easy diagnosis. The 400 KVA UPS with 10 minutes back up time have been installed to keep the cryogenic system running with one 160KW cycle compressor during utility power interruptions.
