[导读]通常伺服系统有三种基本控制模式，即速度控制模式、位置控制模式和转矩控制模式。其中速度控制模式相对简单，主要有数字量输入端子的速度控制、模拟量输入端子速度控制和通信速度控制，类似于变频器的速度控制。 通常伺服系统有三种基本控制 ...

S7-1200 支持Modbus RTU通信模式的模块可作为Modbus RTU从站。以下以 CPU1215C DC/DC/DC和CM1241 RS485为例,介绍S7-1200 Modbus RTU 从站通信组态及编程步骤。 硬件和软件需求及所完成的通信任务： 硬件：① CPU1215C DC/DC/DC (订货号:6ES7 215-1AG31-0XB0)② CM1241 RS485 ...

本方案以西门子S7-1200和S7-200SMART PLC为例，在Profinet协议实现无线以太网自组网通讯。 2台PLC分别通过以太网线连接达泰DTD418MB无线通讯终端，将天线接好以后，给DTD418MB和PLC供电，我们可以给1号PLC的I点输入信号，我们会发现对应的2号PLC的Q点就有输出信号。

S7-1200系列PLC可以通过PROFINET与V90 PN型伺服驱动器组合进行速度控制，S7-1200 PLC负责发送控制命令和速度给定，并读取V90伺服驱动器状态和实际转速；V90伺服驱动器自身完成速度闭环控制计算。本实例没有使用任何专用程序块，由于对报文结构比较熟悉，直接利用 ...
