摘要
Modbus/TCP作为主流的工业以太网标准之一,在工业控制现场得到了广泛的应用。但是Modbus/TCP协议本身并不保证实时性和对数据的并发处理能力。设计并实现了一种基于μC/OS-II的Modbus/TCP协议栈——μCModbus,完全兼容Modbus/TCP标准,并提供时实时性和并发处理的能力。测试结果表明,μCModbus具有良好的实时性和并发处理能力,有较高的可用性。
As a main industrial Ethernet standard,Modbus/TCP has been widely used in the area of industrial controlling.But the Modbus/TCP itself doesn＇t guarantee real-time and concurrency.This paper design and realize a Modbus/TCP stack based μC/QS-11 ,called μCModbus, which is compatible with the Modbus/TCP protocol perfectly.The μCModbus could provide real-time and concurrency service to users.The testing results show that the μCModbus has better real-time and concurren cy capability,and also has high usability.
