The VME based Ion Cyclotron Resonance Heating (ICRH) Data Acquisition Control system (DAC) is commissioned for remote operation of heating experiment on SST-1 Tokamak. ICRH-DAC is physically distributed into two sections at RF Lab and SST-1 hall. RF Generation section at RF Lab and Transmission line, interface and antenna section at the SST-1 hall having its own independent VME based DAC system.VME system of both section is running on master/slave configuration when synchronization mode operation is needed. This synchronization of both DAC could be possible with EPICS (Experimental Physics and Industrial Control System) process variables, which broadcast and describe itself in Ethernet network. The existing system uses the TCP/IP Ethernet network for the same. The proposed program is used for real-time state parameters transmission and storage, dynamic graphical display, modification of the interactive system and synchronization. This paper will describe the conceptual design of EPICS based ICRH DAC software to achieve desired goal of experiment for generic development platform oriented toward complex data acquisition is proposed.
