Abstract: In order to solve the shortages of current monitoring system, such as structure
complexity, high price and inconvenienced maintenance, a multi-purpose monitoring system based the PROFIBUS was proposed in this paper. It includes the monitoring module and a host, and 32 analog input paths were designed as well, which can fit various sensors. The PROFIBUS bus used in the system can accord with other system, so it is with the modern international developing trend.
