Hello, my name is Victor and I am currently pursuing a degree in Automation Engineering. I am a new member of this forum, although I have been following discussions here for the past two years. I am encountering difficulties with a school project involving a FMS-200 system. Specifically, I am attempting to establish communication between a Siemens slave system (315-2 dp) and a master system (also 315-2 dp) via Profibus protocol. I am unsure about how to configure the hardware settings on the slave system. Should I simply add send/receive blocks and assign the Profibus address of the master system? Additionally, in the "Configure Network" settings, should I designate my PLC as a "slave" and assign it the same Profibus address as set in the master configuration? I apologize if this explanation is unclear. Any guidance on this matter would be greatly appreciated. Thank you, Victor.
I successfully resolved the issue at hand!
Hello Victor, can you please share how you resolved your issue? Let me know the solution you found.
Hi Victor! Welcome to the forum officially, even though you've been with us in spirit for a while. Your explanation was clear enough, no need to worry. To answer your questions, yes, you should add send/receive blocks in your Siemens slave system. It's crucial that you assign the Profibus address of the master system to them to allow them to communicate. Regarding the "Configure Network" settings, it would be best to set your PLC as a "slave". However, remember that each device in the network needs a unique Profibus address. The Profibus address in your slave configuration doesn't have to be the same as that in the master configuration. Hope this clarifies things. Good luck!
Welcome to the forum, Victor! The first part of your assumption is correct, you need to add send/receive blocks in the hardware configuration of the slave. Concerning the Profibus address, it should indeed match the one of your master system. However, I’d like to clarify that the Profibus address for the master and the slave system cannot be the same - each device in a Profibus network must have a unique address. As for your second question, you should definitely designate your PLC as a "slave" in "Configure Network" settings. It sounds like you're on the right track, just keep these details in mind to make your system commutate effectively.
Hello Victor, welcome to the forum! In my own work with Profibus protocol, I've found there needs to be clear distinction between the master's Profibus address and the slave's. So, despite your intuition to assign them the same address, I'd recommend against it. Aim to give each a unique address for optimal communication. As for the hardware configuration, adding send/receive blocks is usually a good place to start. Remember, your slave system will be receiving instructions and sending feedback, so configure its settings to align with that role. I hope that helps clear things up. Let us know if you have any additional questions!
Hi Victor! Welcome to the forum! It sounds like you’re diving into an interesting project! For the FMS-200 system and your Profibus setup, you definitely need to assign different Profibus addresses for the master and slave devices; they should not be the same, as each device in a Profibus network needs a unique address. When configuring the slave system, make sure to set it up as a "slave" in the network settings and enter the correct address that aligns with your master setup. As for the send/receive blocks, yes, adding those blocks is essential for communication, and you’ll also want to ensure that you properly define the data you want to send and receive. If you follow these steps and verify your wiring and addresses, you should be able to establish communication successfully. Good luck, and feel free to ask if you run into more specific issues!
Hi Victor! Welcome to the forum! It sounds like you’re diving into an interesting project. For the FMS-200 system communication, you’ll want to ensure that your slave and master systems are properly configured with unique Profibus addresses—each device should have its own address to avoid conflicts. In your slave system, you'll set it as a "slave" in the network configuration, but make sure to assign it a different address than the master system. Once that’s done, using send/receive blocks to handle data exchange is a good way to go. Don't hesitate to check the Siemens documentation for any specific settings required for your model. Good luck with your project!

Answer: - To configure the hardware settings on the Siemens slave system, you need to add send/receive blocks and assign the Profibus address of the master system. Additionally, in the "Configure Network" settings, you should designate your PLC as a "slave" and assign it the same Profibus address as set in the master configuration.
Answer: - You can start troubleshooting by checking the hardware settings on both the slave and master systems, ensuring that the Profibus addresses are correctly assigned. Verify the connection integrity and configuration in the "Configure Network" settings. Additionally, check for any errors in the programming logic related to the Profibus communication.
Answer: - Absolutely! To troubleshoot communication between Siemens S7 systems using Profibus protocol, ensure that the hardware settings are correctly configured on both the slave and master systems. Verify the Profibus addresses, check the network configuration, and review the programming logic for any errors related to the communication setup. Feel free to ask for more specific guidance if needed.
