EPICS based monitoring and control in data acquisition system

Data acquisition plays a great role in control and monitoring systems. There is a wide choice of both the hardware and software solutions for implementing a data acquisition system. The system experimental requirements were met using the Experimental Physics and Industrial Control System (EPICS) which has been standardized by the Control Data Access and Communication (CODAC) system in ITER. It allows building server applications that interact with the hardware and provide an interface to EPICS clients. One of such clients is Best OPI Yet (BOY), which is part of the Control System Studio (CSS) package. It provides an editor and a runtime for developing operator panel interfaces. Among the requirements of the systems were throughputs, high reliability and the possibility to monitor and control data acquisition parameters. There are many systems working in collaborative environment for plasma experiment and connected through Ethernet. This paper shortly introduces the architecture of the designed DAQ system but focuses mostly on the implementation of the EPICS Input-Output Controller (IOC) as well as the operator panels designed in CSS BOY.
