Hello Siemens_lgb; You have to study the MB_Server instruction for your S7-1200 CPU, it places the PLC in Modbus server mode over its integrated Profinet port. Which version of Step 7 TIA Portal are you using to program the S7-1200? Here is a description of MB_Server for Step 7 v16, from the system manual for that version. https://support.industry.siemens.com/cs/ww/en/view/109773506/103787594891 You need to establish a connection to the MB_client (using the parameters of MB_Server discussed in the preceding entry), in the same way you must request data from the server in the Labview client you have programmed. This application example takes the time to describe all parameters of the MB_Client and MB_Server functions , so it might help you coordinate with the Labview client: How do you program and parameterize Modbus/TCP communication between S7-1500 CPUs and S7-1200 CPUs? https://support.industry.siemens.com/cs/ww/en/view/102020340 The following discussion might also help: Hope this helps, |
