摘要
针对天津独流减河除险加固工程的实际情况和计算机监控系统网络架构的具体需求,应用施耐德TSX SCP114通信卡,结合MODBUS协议的特点,对监控系统的现地通信单元进行了组态设计;并从数据采集和数据输出2个方面对TSX SCP114的通信机理进行了深入研究,合理设计通信函数,提高了系统通信性能。
Aiming at the fact of Tianjin Duliujian River Danger removing and Reinforcement Project and the requirement of its supervision and control system network, the configuration of the local communication unit for the supervision and control system is designed by use of Schneider TSX SCPll4 communication card and MODBUS protocol. The communication mechanism of the data acquisition ＆ data output of TSX SCP 114 card is studied deeply, so the MODBUS functions are designed reasonably and the performance of the system is improved.
