ModbusTCP是利用以太网TCP/IP实现的Modbus通信协议，我们可以使用带网络扩展板的Arduino开发板来制作Modbus从机。通过Modbus协议的通讯指令，我们向Arduino中的寄存器发送写指令，通过改变寄存器的状态实现灯光的控制。接下来我们开始组装Arduino，使用到的零件如下：Arduino开发板与Ethernet W5100网络扩展板组装完成后的外观如...

4、在上位机上用Modscan,改变线圈00的数值,观察LED照明变化。 通过本案例,可以初步掌握Arduino Modbus TCP从站开发的基本知识,通过扩展,可开发出更丰富的功能。更多通讯资源请登录登录网信智汇(http://wangxinzhihui.com)。
问Arduino上的Modbus TCP/IPENModbus协议是一种已广泛应用于当今工业控制领域的通用通讯协议，按其格式可分为Modbus-RTU、Modbus-ASCII和Modbus-TCP。其中，前两者适用于串行通信控制网络中，例如RS485、RS232等，而Modbus-TCP主要应用于基于以太网TCP/IP通信的控制网络中。通过此协议，控制器相互之间、或控制器经由网络...
