基于CAN总线的I/O模块设计

Designation of I/O Model based on CAN Bus

提出了一种以CAN总线为基础的过程控制I/O模块的设计方案,介绍了该类型模块的功能、软件、硬件设计方法。用CAN总线实现与通讯模块的数据交换。为保证数据传输的可靠性,在通讯上采用了冗余设计。

In this paper,the designation of I/O module for process control based on CAN bus is introduced.The I/O module＇s function,hardware and software designation are introduced.The redundant designation is applied to ensure the communication reliability.
