Design and implementation of a standard framework for KSTAR control system

Standardization of control system is an important issue in KSTAR which is organized with various heterogeneous systems. Diverse control systems in KSTAR have been adopting new application software since 2010. Development of this software was launched for easy implementation of a data acquisition system but it is extended to as a Standard Framework (SFW) of control system in KSTAR. It is composed with a single library, database, template, and descriptor files. The SFW based controller has common factors. It has non-blocking control command method with a thread. The internal sequence handler makes it can be synchronized with KSTAR experiment. It also has a ring buffer pool mechanism for streaming input data handling. ly, there are two important functional improvements in the framework. Processor embedded FPGA was proposed as a standard hardware platform for specific application. These are also manipulated by the SFW based embedded application. This approach gives single board system an ability of low level distributed control under the EPICS environments. We also developed a real time monitoring system as a real time network inspection tool in 2012 campaign using the SFW.
