J-TEXT-EPICS: An EPICS toolkit attempted to improve productivity

• Tokamak control applications can be developed in very short period with J-TEXT-EPICS.
• J-TEXT-EPICS enables users to build control applications with device-oriented functions.
• J-TEXT-EPICS is fully compatible with EPICS Channel Access protocol.
• J-TEXT-EPICS can be easily extended by plug-ins and drivers.

The Joint Texas Experimental Tokamak (J-TEXT) team has developed a new software toolkit for building Experimental Physics and Industrial Control System (EPICS) control applications called J-TEXT-EPICS. It aims to improve the development efficiency of control applications. With device-oriented features, it can be used to set or obtain the configuration or status of a device as well as invoke methods on a device. With its modularized design, its functions can be easily extended. J-TEXT-EPICS is completely compatible with the original EPICS Channel Access protocol and can be integrated into existing EPICS control systems smoothly. It is fully implemented in C#, thus it will benefit from abundant resources in.NET Framework. The J-TEXT control system is build with this toolkit. This paper presents the design and implementation of J-TEXT EPICS as well as its application in the J-TEXT control system.
