摘要
Modbus TCP通讯协议是应用于工业控制器的一种通用语言。通过此协议,可实现控制器与外部设备之间的通信。在工业控制中,可编程控制器(PLC)作为工业控制装置已得到广泛地应用。具有高可靠性、高稳定性的中广核国产化PLC,可以完美支持Modbus TCP协议。本文描述了Modbus TCP通讯协议应用于中广核国产化PLC中的配置方法,并通过一个通讯实例展示了PLC与SCADA之间的数据交互情况,表明中广核国产化PLC可方便实现与外部设备之间的Modbus TCP通信。
The Modbus TCP communication protocol is a common language used in industrial controllers.This protocol enables remote communication between the controller and the device.In industrial control,programmable logic controller(PLC)has been widely used as an industrial control device.CGN localized PLC with high reliability nuclear power quality can perfectly support Modbus TCP protocol.This paper introduces the configuration method of the Modbus TCP communication protocol applied to the CGN localized PLC,and shows the data interaction between PLC and SCADA through a communication sample,indicates that the CGN localized PLC could support Modbus TCP communication protocol with the host.
