A NETWORK-BASED DAC OPTIMIZATION PROTOTYPE SOFTWARE

Abstract

For the purpose of remote control of heating experiments, a prototype client of an EPICS-based Data Acquisition Control system (DAC) is commissioned. Physically, the ICRH-DAC is split between the RF Lab and the SST-1 building. There are separate DAC servers for the RF Generation area of the RF Lab and the Transmission line, interface, and antenna area of the SST-1 hall. Both are based on Versa Module Euro card (VME) technology. Both DACs' Linux clients are now linked through Ethernet. The parameters utilized in an experiment are exchanged between the master and slave DAC clients via the master's role as an Input/Output Controller (IOC) server in the Experimental Physics and Industrial Control System (EPICS). The Control System Studio (CSS) suite includes a client called Best OPI Yet (BOY). It includes both a coding environment and a runtime for creating control panel operator interfaces. In this paper, we present the user-perceived performance test findings and describe the prototype software. We provide an analysis of the performance data and its meaning in light of the memory architecture, the processing power, and the particular networking protocols used. We can pinpoint the performance bottlenecks and determine how to fix them thanks to our in-depth investigation. EPICS's Channel access layer and the operator panels built with CSS BOY have been incorporated into the software that was developed using EPICS's Input-Output Controller (IOC).
