Provided is a profibus active terminal resistance device with DP bus data acquisition function, comprising an active terminal resistance module, a DP data acquisition module, a power interface, a backplane interface and a DP bus interface. The active terminal resistance module has the function of suppressing the reflection and distortion of the Profibus DP signal, the DP data acquisition module receives the bus data of the DP segment of the device through the physical layer transceiver, analyzes the received bus data, classifies and uploads the backplane interface. The profibus active terminal resistance device with DP bus data acquisition function is connected with the terminal of the Profibus DP network segment, and has the advantages of controling bus signals, prolonging signal transmission quality, collecting the communication data at the same time in the DP network, and providing the data base for the diagnosis and analysis of monitoring system through the ethernet communication module is uploaded to the Profibus bus monitoring diagnostic system.
