通讯协议在氯碱行业中的应用

Application of communication protocol in chlor-alkali industry

阐述了Modbus协议的含义及其数据传输方式,介绍了利用Modbus协议进行温度数据采集的设置方式,以及将大型机组的工作参数通讯至DCS的方法。通过通讯协议可将多方面数据通讯至DCS,降低了劳动强度,提高了设备运行的稳定性。

The meaning and data transmission mode of Modbus protocol was expounded, and the setting method of temperature data collection by using Modbus protocolwas introduced, as well as the method of communicating the working parameters of large unit to DCS. Data from different sources could easily communicate to DCS through the communication protocol, and thus the labor intensity was reduced, and the stability of equipment operation was improved.
