10.2 Profibus PAInstrument master fileThe 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 valuesand 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 automaticallywhen the GSD file is integrated. The bitmap file is used for symbolic indication of the PA instrument inthe configuration tool.Ident numberEach Profibus instrument gets an unambiguous ident number (ID number) from the Profibus userorganisation (PNO). This ID number is also included in the name of the GSD file. For VEGACAL 62the ID number is 0x076E(hex) and the GSD file CL__076E.GSD. Optionally to this manufacturer-specific GSD file, PNO provides also a general so-called profile-specific GSD file. For VEGACAL 62you have to use the general GSD file PA139700.GSD. If the general GSD file is used, the sensormust be set to the profile-specific ident number via the DTM software. By default, the sensor operateswith the manufacturer-specific ID number.Cyclical data trafficThe master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during operation.The below block diagram below shows which data can be accessed by the PLC.pF % Lin%Min-Maxadjustment LinearizationPROFIBUS PA-outputPrimaryValueSecondaryValue 2SecondaryValue 1TargetModeFailuremodeAlarmsScalingSource forscalingtiDampingSensorcharacteristicsPA-OutTBFBSelect additional cyclicvalueFig. 25: VEGACAL 62: Block diagram with AI (PA-OUT) value and additional cyclical valueTB Transducer BlockFB Function Block48 VEGACAL 62 • Profibus PA10 Supplement30025-EN-090603
