Good day! Please help with the solution of the same problem 8180 of the MB_MASTER block! I tried all the recommendations that I found on this forum, as well as on the Internet, but nothing helps. Controller S7-1200, TIAPortal V15.1. I'm new to this. I check in simulation, compile, load into the controller, press RUN / STOP - it does not help. The "Optimization ..." checkbox is unchecked for blocks (screenshots). I am attaching screenshots. PS. Modbus RTU did it based on this video - https://www.youtube.com/watch?v=eH3UUMKy_I0 - but in the video everything works, but I don't ... ------------------------------------------------------------------------------------------ AttachmentError 8180 MB_MASTER.docx (833 Downloads) |

Hello. The error message (8180) says: "Invalid value for the port ID". You say: "I check in simulation". Are you simulating with PLCSIM? You need actual hardware. PLCSIM does not work for Modbus RTU. The S7-1200 is the master - what is the slave? How does your connection look like? Regards. LATE ADDITION.. What happens if you use actual hardware? |

Dear qwazee! I do not have operating equipment yet, but it will be purchased a little later. I really do the simulation programmatically on PLCSIM. I assumed that the Modbus port most likely did not work on PLCSIM, but, unfortunately, I didn’t know for sure, and no one suggested it. This is my first time programming Siemens controllers. Thank you for taking the time and confirming with screenshots! Hope you are 100% right, and when the real hardware arrives, this port error will be gone! Thank!
