摘要
本文从实际要求出发,介绍西门子通信模块CP341与智能电表之间两种基于Modbus总线协议的通讯方案的实现。首先介绍CP341与智能电表通讯所需要的硬件配置;然后阐述两种方案如何通过PLC软件编程来读取智能电表的实时数据;最后介绍常见的故障诊断方法。
Starting from the actual requirements,the realization of two communication schemes between SIEMENS communication module CP341 and smart meter based on Modbus bus protocol was introduced.Firstly,the hardware configuration of CP341 and smart meter communication were introduced.Then the two schemes,how read the real time parameters of the smart meter through PLC software programming,were introduced.Finally,the common fault diagnosis was briefly analyzed.Practice proved that the two schemes could meet the requirements well and achieve reliable communication.
