摘要
随着工业技术的发展,Modbus协议已经不仅仅用在PLC与上位机的通讯,越来越多的现场设备都已开始支持Modbus,这大大的扩展了Modbus的应用。详述了一种通过XXMIT指令实现昆腾PLC直接与现场设备进行Modbus RTU通讯的方法。
With the development of industrial technology, the Modbus protocol has not already only used on the communication between PLC and host computer, but also more and more field equipment began to support Modbus, which largely expand the application of Modbus. Introduces the method that can realize directly Modbus RTU communication between quantum PLC and field equipment through XXMIT instruction.
