以太網(wǎng)現(xiàn)場總線的跨平臺網(wǎng)絡(luò)通信

核聚變裝置EAST 極向場電源控制系統(tǒng)由三層網(wǎng)絡(luò)組成：WINDOWS 監(jiān)測層、QNX
實時控制層、現(xiàn)場總線執(zhí)行層。其中現(xiàn)場總線層負(fù)責(zé)采集大量現(xiàn)場設(shè)備的狀態(tài)并將其傳遞給實時控制層和監(jiān)測層。本文描述了以太網(wǎng)現(xiàn)場總線控制器與QNX 和WINDOWS 不同操作系統(tǒng)之間的一種跨平臺網(wǎng)絡(luò)通信。實踐表明基于MODBUS TCP/IP 協(xié)議，利用Socket API建立的套接字使現(xiàn)場總線同時與兩種操作系統(tǒng)之間進(jìn)行通信是完全可行的，而且是高效的。

Network Communication between differ Flats Of Ethernet Fieldbus Lanluguang Fupeng Yangyalong Wuyong (Institute of Plasma Physics Chinese Academy of Science，Hefei，230031) Abstract: The poloidal field power supply control system of the nuclear fusion device—EAST is constituted of three layer networks: WINDOWS monitor layer,QNX realtime control layer,Fieldbus layer.The Fieldbus layer is responsible for collecting a great deal of
equipments'status and delivering them to the control layer and the monitor layer. This paper
describes network communication between QNX ,Windows operate system. and Fieldbus. The practice shows that the communication on network between the two operate systems and Fieldbus is entirely feasible and high efficiency, with the socket built on socket API based on MODBUS TCP/IP.
