【摘要】 现代电力系统中的某些厂站,运行人员后台监控系统采用基于Profibus通信规约的主站系统,因此应用于这些厂站的测控装置必须增加Profibus通信功能。为了验证单装置调试期间测控装置Profibus通信的正确性及测控装置其他相关性能,基于CP513主站通信卡,利用VC++编程软件设计了Profibus-DP仿真主站。仿真结果表明该仿真主站可以提高测控装置厂内测试及现场调试时的工作效率。更多还原

【Abstract】 For some modern power system plants or stations, monitoring system communication protocol is based on PROFIBUS, and monitoring and control device applied to these stations must add PROFIBUS communication function. In order to test and verify PROFIBUS communication function and other related performance conveniently during a single device debugging period, A PROFIBUS-DP simulation master station is designed based on CP513 master communication card and VC ++ programming software, simulation result has proven it can improve the efficiency of device testing and debugging.更多还原
