Accurate Data Acquisition and Control (DAC) system is the basic element for operation and control during Tokamak experiments. This research is about the software solutions for the instrumentation system that is free of cost, open source and multi-domain utilities applicable to cryogenics test facilities without the need of high cost license procurement for SCADA. A DAC system supports slow and fast operation and control. Using this architecture, it can be feasible to replace high cost SCADA software with its own open source tools for ease of communication and interfaces of heterogeneous hardware. This work introduced multi-domain technologies that facilitate the goal of bringing control system User Interface (UI) to the web for IoT application. Python libraries are used as a future tool for IoT implementation which has been established by this modular architecture using EPICS toolkit. Any Modbus supported instrument control system can be accessed and operated using a web browser as an IoT application which can run on secure public encryption. This solution can interface most of the industry standard PLCs on IoT platforms which can run on credit card sized single board computers. This conceptual DAC software can be used for control of cryogenic test facilities.
