Profibus-DP

7 Profibus-DP network configuration7.1 Network data rateThe network data rate is automatically recognised by the UD73 and MD24.The following network data rates (in bits per second) are supported:9.6 Kbps 19.2 Kbps 93.75 Kbps 187.5 Kbps 500 Kbps 1.5 MbpsIdentification numberA Profibus-DP slave will only accept data from the master controller if theIdentification Number received from the master matches its own internalIdentification Number.The UD73 and MD24 have the Identification Number of 0x3345, so the datashould be entered as:Ident_number_high byte = 0x33.Ident_number_low byte = 0x45.7.2 Configuration telegramPLC configuration filesWhen the network is initialised, the master will transmit the configurationtelegram to each slave. If this does not match the configuration telegramwithin the slave (0xB7), the master will not be able to initialise the nodecorrectly. Data consistency is required over all 8 bytes.The configuration files listed below are supplied with the DPL Toolkit. Thefiles can be found in the C:\MD29GUI\BIN directory in the ZIP file,PROFIDP.ZIP.Filenamectc-3345.gsdct3345td.200ct3345ax.200DescriptionGeneric PLC Profibus-DP configuration fileSiemens S5 PLC Profibus-DP configuration file compatible withSiemens V4.0 softwareSiemens S5 PLC Profibus-DP configuration file compatible withSiemens V5.0 softwareProfibus–DPIssue code: pbnu2 27
