  EPICS is mature in accelerator community. However, there are endeavors to improve existing control system software like Tango and EPICS 7 mainly driven by the needs of flexibility of the control system and the development of computer technology. This paper presents a new way of building a large experimental device control system using web technology instead of EPICS toolkit. The goal is to improve the interoperability of the control system allowing different component in the control system to talk to each other effortlessly. An abstraction of the control system is made. The control system components are abstracted into resources. The accessing of the resources is done via standard HTTP RESTful web API. HMI is based on HTML and JavaScript in browsers. Web Socket is used for event distribution. The main feature of this design is that all interfaces in the system are based on open web standards, which are interoperable among almost all kinds of devices. The paper also presents a software toolkit to build this kind of control system. A control system for a diagnostic on J-TEXT tokamak built using this toolkit will be presented.
