IFC 300PROFIBUS PA 33.5 GSD files for the data transferA PROFIBUS GSD ZIP file (e.g. GSD-31777813.zip; including both all GSD files and additional datafiles) you can get on a CD ROM or can be downloaded from the internet. The GSD file containsinformation that will be needed for project planning of the PROFIBUS communication network.The relevant data files (e.g. _ _ _ _ .bmp / _ _ _ _ .dib) must be loaded into the bus configurationsystem/master system before start-up of the bus system.3.5.1 Cyclic data exchangeDuring network configuration the user has to define which function block outputs of the signalconverter should be transferred cyclically to the master. Network configuration will be doneusing one of the GSD files described before. The order of transmission of a function block alwaysremains the same even if a function block is defined as an "Empty" block (if so, no function blockoutput data will be sent to the master and all function block outputs following the empty blockwill move up one position).3.5.2 Ident.-No. supportedThe signal converter with PROFIBUS MBP interface is based on PROFIBUS PA Profile V 3.0. Thedevice supports three Ident-No.:• Ident-No. "4501hex" belongs to the GSD file KR024501.GSD and YP024501.GSD and includesthe complete functionality of the electromagnetic flowmeter.• The application of the manufacturer independent Ident-No. "9740hex" (GSD file"PA039740.GSD") provides interchangeability of devices, i.e. an exchange of electromagneticflowmeters of different vendors.• Ident-No. "F401hex"For detailed information refer to Signal converter IFC 300 PROFIBUS PA with MBP interfaceas replacement for older signal converter IFC 090 PA on page 23.Please follow the instructions in the manual of the host supplier when installing the GSD File youneed and the additional files (_ _ _ _ .bmp and _ _ _ _ .dib) into the PLC.INFORMATION!If separated by the bus configuration system the device entry of the PROFIBUS MBP interfacewith PA Profile 3.0 will be located within the slave family PROFIBUS PA.02/2011 - 4001086601 - AD IFC 300 PROFIBUS R01 enwww.krohne.com19
