Abstract:Using Socket API, Ethemet fieldbus based on Modbus TCP/IP protocol can communicate with several computers under QNX6.20 RTOS. The best multi-computer communication cycle is determined by experiments, so that computers can control and monitor the field equipments reliably and in real-time. It is applied to a poloidal field power supply control system of nuclear fusion device, then stability and real-time of communication are improved.
Keywords:QNX
