Greetings! I am currently working on two projects involving S7-1214 PLCs - "Project1" with an MTP1500 HMI and "Project2" with another S7-1214 PLC. Both PLCs require communication with the HMI, and I have successfully set up a connection in the HMI for Project1. However, I am uncertain about the setup for Project2. I have configured a new connection in the HMI for Project2 by entering the IP address of the PLC. Should I also make an additional connection in the Devices/Networks/Connection settings of the Project2 PLC, or is the connection already established? (Please disregard the S7 Connection as it is intentional.) Remember, proper communication setup is essential for seamless operation.
Wondering how to link two S7-1214 PLCs to a single KTP600 PN HMI? Get industry support from Siemens experts on this topic - Article 65957.
Hello Moggie! The PLCs linked are part of the same project, but mine are actually spread across different projects.
To interact with the second PLC, you can either specify all settings manually using absolute addresses or designate it as a "proxy PLC." This feature allows for seamless integration and configuration. Visit SIOSsupport.industry.siemens.com for more information on PLC support.
Thank you, Jesper. I believe I have resolved the issue by duplicating the PLC within the smaller project. However, I encountered a message stating "No PLC found in project" when attempting to utilize device proxy. Can I still use PUT/GET within the same project to communicate between PLCs, or is there a more straightforward method available? My PUT/GET configuration is already set up – can I keep it as is?
swedeleaner mentioned that they were able to address the issue by mirroring the PLC in the smaller project, which is a common workaround in situations where suppliers are hesitant to share the entire PLC program or when different versions of TIA are being used. Moving forward in the same project, the question arose whether PUT/GET functionality would suffice for PLC to PLC communication or if there is a simpler method available. The PUT/GET configuration is already set up and can be left as is for now. It is important to note that the PLC performing the PUT/GET function must have an unspecified connection to the other PLC and should not establish a fully specified connection that requires data to be loaded onto the partner PLC. While BSEND/BRECV would be preferred, it is not compatible with the S7-1200 model.
You're right, proper communication setup is indeed key for streamlined operation. Since you have already configured a new connection in the HMI for Project2 by entering the IP address of the PLC, half the job is done. Now, for the next step, I would advise you to go ahead and also establish a connection in the Devices/Networks/Connection settings of the Project2 PLC. This step is crucial to ensure both ends - the HMI and PLC - recognize and communicate with each other flawlessly. It's always better to double-check these settings to avoid any miscommunication during real-time operations. Hope this helps!
Hello! Based on your situation, it sounds like you've already established a connection between the HMI and Project2's PLC through the HMI. However, it wouldn't hurt to configure an additional connection in the Devices/Networks/Connection settings of the Project2 PLC. With both the HMI and the PLC actively maintaining the connection, you're likely to achieve a more robust communication channel and a more reliable operation. Remember that in complex systems like yours, redundancy is not necessarily a bad thing – it can serve as a safety net for unforeseen circumstances. Good luck with your projects!
In the TIA Portal, once you've established the HMI connection parameters for each PLC (like you've done for Project1), there's no need to create additional connections in the Devices/Networks/Connection settings of Project2's PLC. The link is made at the HMI level, which allows for communication to multiple PLCs. As long as the appropriate IP addressing is set, the communications should function seamlessly. One note though, ensure that both PLCs have different yet compatible IP addresses to avoid any IP conflicts.
Hey there! It sounds like you're on the right track with Project2. Typically, after setting up the IP connection in the HMI for Project2, you should indeed check the Devices/Networks/Connection settings on the S7-1214 PLC to verify that the connection parameters match what you configured in the HMI. Even if the new connection is set up in the HMI, the PLC needs to have a corresponding connection established to communicate properly. It’s always good to double-check the settings and ensure both devices are in the same subnet, too. Good luck with your projects!
It sounds like you're on the right track with configuring your HMI for Project2! In addition to entering the IP address in the HMI for Project2, you should definitely set up a new connection in the Devices/Networks/Connection settings of the Project2 PLC. This will ensure that the PLC recognizes the HMI as a valid communication partner and facilitates proper data exchange. Each project operates independently in terms of connections, so having everything properly configured on both ends is crucial for a seamless operation. Good luck with your projects!

Answer: - To set up communication between the S7-1214 PLC and MTP1500 HMI, you need to configure connections in both devices. Ensure you have the correct IP address entered in the HMI and establish a corresponding connection in the PLC's Devices/Networks/Connection settings.
Answer: - Yes, for each project involving a different S7-1214 PLC, you will need to create a new connection in both the HMI and PLC. Enter the specific IP address of the PLC for Project2 in the HMI, and set up a corresponding connection in the PLC's network settings.
Answer: - Yes, it is essential to create a connection in the Devices/Networks/Connection settings of the Project2 PLC, in addition to setting up the connection in the HMI. This ensures proper communication between the PLC and HMI for seamless operation of the system.
