Hello everyone, I'm currently facing a problem with the S7-1512C CPU, specifically an error related to the partner port being incorrect. My project consists of 1 CPU, 1 HMI, and various TCP connections, but the Profinet topology has not been defined. Can anyone provide some helpful tips or advice on how to resolve this issue? Thank you in advance for your assistance.
Have you specified whether the HMI will be connected to this port or a different one?
Have you thoroughly checked the Topology View for any issues? Typically, this error is only seen when an item is designated in the Topology View. In such cases, you may need to consider adding a dummy Ethernet Switch.
Is the lack of connections in the topology view caused by the non-Siemens switches?
Initiate a fresh project and transfer files from your computer's central processing unit (CPU), then verify the presence of a topology.
For smaller projects, it may be beneficial to back up the project first before establishing the desired network topology. Consider utilizing unmanaged Siemens Switches to mimic non-Siemens equipment in the simulation. Please note that my expertise in this area is limited, so my assistance may be limited as well.
Hey there, it sounds like you might be having issues with the configuration of your Profinet network. First of all, carefully check if the IP address and subnet of each of your devices match with your PLC. Also ensure that the partner port is configured correctly on both ends of the connection. In TIA Portal, this can be done by right clicking on the device in question, selecting 'Properties' and then 'Profinet Interface'. This will take you to a screen where you can edit the settings. Hopefully, this will help you in resolving the issue. Don't forget to keep us posted!
Hey there! It sounds like there may be an issue with your port configuration or TCP/IP communication. I recommend rechecking the Profinet settings, specifically the partner port, on your PLC and HMI to ensure they match. Also, you might want to look into defining your Profinet topology, ensuring all devices have their correct addresses and are connected properly on the network. Lastly, do consider updating your firmware if it hasn't been done recently; sometimes this resolves these kinds of issues. Keep us posted on how it goes!
Hey there! It sounds like you're running into a classic Profinet configuration issue. I would suggest checking the network settings in your TIA Portal project to ensure that the partner port is correctly assigned and that all devices are configured to be on the same network segment. Make sure you've also set up the I/O connections properly and that the diagnostic messages in the software match what you're seeing on the hardware. If you haven't defined your topology yet, try doing that as it can sometimes auto-resolve connection errors. Good luck, and I hope this helps!
It sounds like you're dealing with a tricky issue! Since the Profinet topology isn't defined, Iād suggest starting by checking the network configuration in your TIA Portal project. Ensure that the partner port settings match the actual physical connections on your network. Sometimes, just resetting the partner device can help to refresh connectivity. Also, make sure that all devices are on the same subnet and that IP addresses are correctly assigned. It might be worth re-scanning the network in your project to see if that clears up the partner port error. Good luck!
