Implementation of remote participation at Tokamak device experiments

Abstract

The paper describes the software implementation of remote participation at Tokamak device experiment, particularly hardware remote control and monitoring implementation. This is an alternative to the traditional implementations based on such software kits as MDS+ and PK IVK used at Russian and foreign Tokamak devices: T-10, T-15, JET, JT-60, FTU. Traditional implementations are outdated and require deep modification for effective usage at new devices, so the new implementation is rather actual. The implementation is based on the use of new unified communication protocol for Tokamak subsystems - T-ICS. The protocol takes into account the individual peculiarities of subsystem hardware platform and provides the means of message encryption required for communication using Ethernet-based networks. The comparison of traditional approaches and the described implementation was also described. The implementation of the approach proposed was shown using a TRACE MODE SCADA for the experiment automation system hardware control at one of the foreign Tokamak devices. The use of the new implementation combined with SCADA allows significant automation of the applications development, simplifies hardware control and monitoring command language. At the present the software implementation was tested on the models of the active foreign Tokamak subsystems and it is currently used for model subsystem control. Because of the high potential of the mechanism is going to be integrated into control system of modified T-15 Russian Tokamak.
