摘要
本文介绍了在低压配电站电量监测系统中，ABB公司电力监测部件（PMC916和RS132）与上位监控计算机之间基于Modbus的数据通讯。重点描述了在“组态王6．0”通用组态软件平台下的Modbus RTU通信协议及其配置方式，以及通过ModBus对配电柜的进线电压、电流、频率、断路器运行状态等电量和信号实施监测的过程。
This article introduces the data communication between ABB＇s power monitoring modules of PMC916 / RSI32 and the host supervisor computer based on Modbus in the electric quantity monitoring system of the LV power distribution station. The author focuses on description of ModBus RTU communication protocol and its configuration pattern under ＂Kingview6.0＂ general configuration software package and also recounts the monitoring process of, through Modbus, electric quantities and signals, such as inlet voltages, currents, frequency and breaker operation states at the distribution cabinets.
