基于CAN的分布式数控系统通讯技术研究

The communication research of distributed NC system based on CAN bus

提出了基于CAN的分布式数控系统通讯模型,设计了PC机,CAN网络适配卡、PLC、全数字伺服驱动器三者之间应用层通讯协议。

The communication model of distributed NC system based on CAN bus is presented in this paper and the communication protocol in the application layer among PC,CAN net adapter card,PLC and digital servo driver is designed too.
