Hello Hajaks; The Krohne flowneter can communicate over Profibus-PA (not Profibus-DP), HART or Foundatioj Fieldbus, all instrumentation networks. Profibus-PA requires some form of coupler to connect to a Profibus-DP network master (such as your CP 1542-5). https://www.instrumart.com/assets/Krohne-IFC100-datasheet.pdf The following links will give you a basic description of how a Profibus-PA coupler links a Profibus-PA instrument to a DP network; note that the master must then be setup at a speed of 45,45 kB for this to work: - Procentec presentation on Profibus-PA : PROFIBUS PA is linked via coupler to PROFIBUS DP. The coupler translates the DP telegrams that come from the master to PA telegrams (data and power supply) on the same two wires. The answers of the PA instruments are translated back to PROFIBUS DP. The translations are electrical, because the protocol remains intact. https://procentec.com/content/what-is-profibus-pa/ - Siemens Profibus-PA coupler; FIELD DEVICE COUPLER FDC 157 Field Device Coupler FDC 157 physical interface for PROFIBUS PA or Foundation Fieldbus H1 integrated bus supply up to 1000 mA with redundancy capability integrated diagnostics Degree of protection IP20 for extended temperature range - How do you set up the DP/PA link and how do you configure the DP/PA link and DP/PA coupler? https://support.industry.siemens.com/cs/ww/en/view/51678187 Hope this helps, Daniel Chartier |

Hello Daniel Chartier My flowmeter can communicate with Profibus DP im pretty sure about that. We are running several ones with communication to S7 300 systems. But this is the first one that we are running against S7 1500. https://www.instrumart.com/assets/Krohne-IFC100-Manual.pdf See page 35 Best regards

Hello Hajaks; I apologize, I thought I had read that only the IFC 300 allowed Profibus-DP. In that case, have you accessed these supplementary instructions for Profibus-DP for the Khrone IFC 100? They might offer help on the configuration of the Profibus-DP interface. Signal converter for electromagnetic flowmeters - Conaut Also, if you could give us a screenshot of the configuration of the flowmeter in your project, especially the addresses selected for each data module, we could probably help you in your data exchanges. Hope this helps, Daniel Chartier |
