Abstract :
A new microwave system operating at the second harmonic of the Electron Cyclotron Resonance is currently being installed on TdeV. Its control and protection system offers versatility with its multi-level structure. The primary level is the hard-wired protection system that uses programmable logic device technology (PLD). This system is dedicated to protect with a fast response time personnel and critical equipments, The second level consists of a programmable logic controller (PLC), the Siemens TI555. It is used for over-all supervision, monitoring status and slow control and protection tasks. The last level is the user interface. It uses commercial software running on a VAXstation 4060. This paper describes in details the control and protection systems and its components
