An embedded PC based Controller module, named System Controller Module (SCM), has been developed at Reactor Control Division(RCnD), BARC. This module uses standard PC-104 bus based CPU module integrated with a protocol translator card to provide an interface between the CPU module and VME bus. The signal interface between PC-104 bus of CPU module and translator card is achieved through stackable connectors. SCM can be interfaced with 16-bit slave I/O modules on VME bus for Data Acquisition and Control. This development provides low cost PC based platform for developing I/O intensive embedded system requiring high processing power. SCM module is fully compatible with PC architecture and is available in Double Euro modular form factor. Module has self diagnostics features to test software integrity using onboard watchdog timer. The module provides dual Ethernet link for communication. The SCM has been assembled, integrated and successfully tested along with VME based high speed data acquisition system (Machinery Protection System), which has been developed in RCnD for condition monitoring of rotating machines. SCM acts as a configuration controller and data manager for this system.

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.
