Hello, You should use PROFIBUS cable with PROFIBUS connectors with resistor for your MPI communication. PROFIBUS connectors You should integrate your WinCC flexible project in Step7. How do you integrate a WinCC flexible project in STEP 7? Then you can interconnect the panels and CPU in STEP 7 ( NetPro). Tweety |

Hello, Do you have enough OP Communication Connections in HW Config? You find fhissettings, Properties of your CPU > folder "Communication". Tweety |

Have you set the first and the last resistor of the connector?
Have you set "the Panelis only master on the bus" on the panel, PC/PG interface settings and your WinCC flexible project? The parameters of the transfer settings in the Control Panel are overwritten from the parameters of the WinCC flexible project.
The following FAQ can you see for connection between Panel and PLC via Profibus. How do you configure a connection between WinCC flexible Runtime (PC/Panel) and a SIMATIC S7-300/S7400 via PROFIBUS/MPI? Tweety |
