基于无线传输的PLC与远程IO现场总线控制方案

A field bus control solution through wireless transmission

本方案论述了一种通过工业无线接入点,工业无线客户端实现PLC的CPU与远程IO进行现场总线的无线传输。在一定范围内移动的装置上有一些控制信号,通过实体线路与PLC的CPU进行实时信号传输相对比较困难。采用无线的方式进行信号传输则是一种比较好的选择。在设备控制中心PLC的CPU处安装工业无线接入点。在移动装置上安装工业无线客户端,通过无线客户端和无线接入点的无线配对通讯实现PLC与远程IO模块的控制信号传输,满足PLC对移动装置上的信号控制。

This solution discusses a method of wireless transmission between PLC CPU and remote IO on the field bus through industrial wireless access points and industrial wireless clients.There are some control signals on devices that move within a certain range,and it is relatively difficult to transmit real-time signals to the CPU of the PLC through physical circuits.Wireless signal transmission is a good choice.Install an industrial wireless access point at the CPU of the PLC in the equipment control center.Install an industrial wireless client on the mobile device,and achieve control signal transmission between the PLC and the remote IO module through wireless pairing communication between the wireless client and the wireless access point,meeting the signal control of the PLC on the mobile device.
