11 Supplement 11.2 Information on Profibus PA Instrument master file The instrument master file (GSD) contains the characteristic data of the Profibus PA instrument. These data are, e.g. the permissible transmission rates as well as information on diagnostics values and the format of the measured value outputted by the PA instrument. A bitmap file is also provided for the Profibus network planning tool. This file is installed automatically when the GSD file is integrated.
