Currently the 10MeV Linac is being used for different research applications and industrial use. The control system in operation was developed using CAMAC based DAS, backed by Hard-wired Interlock System. It is proposed to replace the CAMAC system with a state-of-the-art indigenously developed PLC that is verified to the level of a Class IB computer-based system used in nuclear power plants. A PLC node comprises of two VME bus based CPU boards (PowerPC MPC7447, 600MHz) working in redundant mode. The Inputs and Outputs are common to both CPUs. The intelligent I/O boards are hot swappable. The PLC hardware and software has undergone rigorous verification and validation. A user-friendly development environment is provided to the process engineer for building the application using pre-defined function blocks. The LCS developed using PLC is to be used for operating the Linac irradiation facility, remotely as well as locally in a fail-safe mode, with sequential start-up and sequential shut-down. Apart from system status monitoring, data archiving, alarm generation and setpoint adjustments, it shall monitor the important parameters and trip the GM HV, KM HV and EG PS on fault conditions.

The control system of Electron Cyclotron Resonance (ECR) ion source is computer based control system. Main components of ECR ion source are microwave generator, plasma chamber, solenoid magnets, high current power supplies, extraction electrodes, high voltage power supplies, beam measuring devices and vacuum system. All the electronics devices have their built in microprocessor base electronic interface, which can be remotely accessed by serial or Ethernet link. Two numbers of Ethernet to four port serial converter modules are used to extend the serial interface capabilities of computer. Serial interface of all the devices are connected to the extended serial ports of the computer. Serial link of high voltage power supplies are optically isolated using optical isolators to overcome EMI and EMC problems. Software has been developed in house for remote operation of the ECR ion source electronic devices like magnetron power supply, high voltage power supplies, high current power supplies, microwave power measurement and vacuum gauges.
