A bus monitor can be used to log telegrams on the PROFIBUS.
Modern bus monitors generally have the following features:
•Protocol analysis for PROFIBUS DP and PA networks
•Device capture and clear display of PROFIBUS network structure
•Online analysis of all the main parameters in the network, PROFIBUS master and all connected slaves
•Logging and display filter
•Telegram decoding for FDL, DP, DP-V1 and DP-V2
•Telegram logging, including prolonged recording
•Automatic production of a test report
•Multilingual user interface
These days, automatic generation of a measurement report is an important function for producing an acceptance protocol for any PROFIBUS system.
