基于Modbus通信的电子送经控制方案研究

介绍了一种基于伺服驱动器Modbus通信协议的经编机的电子送经控制系统,并提出关于CRC校验码计算和基于串行通信的伺服电机运行控制的梯形图程序设计。最后以具有6个经轴的经编机电子送经系统为例,计算分析PLC控制单元对6个伺服完成一次数据刷新需要的时间。该电子送经控制系统配线简单、通信速度快、可靠性高,能够满足实际生产要求。

Study of the electronic let-off control scheme based on Modbus communication

This paper introduces an electronic warp let-off control system based the communication protocol of servo diver Modbus,and puts forward the ladder diagram program design which uses the CRC check code computation and is based on the servo motor of serial communication.In addition,taking the electronic warp let-off system of six beams as an example,this paper calculates and analyzes the time for one-time data refresh of the PLC unit to control the six servo motors.It shows that the developed electronic warp l...
