摘要
在现场总线控制系统中,利用嵌入式工控机PC/104作为CAN现场总线通信控制管理器的微控制器,并作为下位机CAN节点和上位PC机的通信桥梁,双向传送上位机和下位机的数据。文中详细阐述了嵌入式工控机PC/104利用RS232串行通信协议完成与PC上位机的通信,及利用CAN通信协议对下位CAN控制节点的通信的各个模块设计。
In the field bus controlling system,the embedded industrial controlling computer PC/104 was used as the microcontroller of the CAN field bus manager of communication and control,it also acts as the communication bridge between the upper level PC and lower level CAN, transmitting the data from both direction. This paper expatiates in detail about how the embedded industrial controlling computer PC/104 finished the communication with the super level PC using the RS232 communication protocol and the module design using the CAN communication protocol to the lower level CAN control
