基于MODBUS RTU通信协议下的CRC算法实现

Application of CRC Algorithm Based on MODBUS RTU Communication Protocol

MODBUS协议是应用于电子控制器上的一种通用协议,通过此协议,控制器相互之间、控制器通过网络(例如以太网)和其它设备之间可以通信。如今MODBUSRTU协议已经成为我国工业自动化网络协议规范的国家标准之一。本文详细讨论了遵守MOD-BUSRTU协议的传输数据的CRC算法验证实现。

MODBUS Protocol is a kind of common protocol applied to electron controls.Use the protocol,Controls and others,Controls and other equipments could communicate with other Net（for example Ethernet Network）. Now, MODBUS RTU has become a kind of National Standardization at net protocol criterion of industrial automatization,This paper will discuss detailedly the application of CRC algorithm check the transfer data abide by MODBUS RTU Protocol.
