摘要
介绍了PROFIBUS-DP现场总线通信协议的主要特点,阐述了基于PROFIBUS-DP通信协议的主从系统进行数据传输的基本原理,并在此基础上讨论了在某过程控制实验系统中采用PROFIBUS-DP主-从结构,进行主站与多智能从站间的通信问题。
PROFIBUS-DP technology was introduced, and the principle of the communication between the master station and slave station based on PROFIBUS-DP was described. The method of design and realization of master-slave structure based on PROFIBUS for process control experiment system was discussed.
