Greetings all! I am a beginner in setting up produced and consumed tags between PLC Controllers. Is it necessary for both controllers to have the identical model and revision number?
Yes, Logix 5000 controllers can vary in models and revisions, such as ControlLogix and CompactLogix.
I appreciate the prompt reply, it's good to have this information on hand. Thank you!
When setting up P&C tags, it is common practice to add each PLC processor to the other's IO tree. However, this can become problematic if one PLC is significantly older than the other and the newer one is not compatible with the older one's project. In such cases, it is usually successful to use a similar CPU model that follows the same path as the unavailable one. For instance, if the older PLC is a 1756-L55Mxx and the newer one is a 1756-L7x, you can work around this by considering the -L7x as either an -L5x or -L6x, whichever is the latest version compatible with the -L55 model. Issues may arise if the newer PLC is an L8xE and you are connecting via the embedded Ethernet port, as it belongs to the newest ControlLogix family. In this scenario, it may be advisable to initially configure the older PLC to recognize it as a CompactLogix with a built-in Ethernet port.
It is essential to define the "consumed" tag carefully, as the processor version defaults to the most recent installation on your device. If the project is passed on to someone with a different version, they may face difficulties when making changes. This highlights the importance of compatibility when collaborating on projects.
When setting up Produced/Consumed Tags, only the tag names, data types, and CIP Path are crucial. In my view, Studio 5000 should not prompt for the model or firmware revision as they are not utilized for keying. It can be challenging to get the CIP Path correct, especially when using an older version of RSLogix 5000 that does not support modern built-in Ethernet ports. However, a common workaround is manually adding a controller that is similar but not identical. There have been claims about the firmware impacting P/C Tags functionality, but it usually boils down to syntax errors or misconfigured CIP Paths, or a network unable to handle the traffic effectively.
Hi there! Generally, it's not mandatory for the PLC controllers to be of the exact same model or revision for producing and consuming tags. The critical aspect to ensure is that both the PLCs support the tag sharing feature, and you configure them correctly. However, using identical models might make the configuration process easier because the settings and interface would be the same. If you're using different models, make sure to thoroughly understand each controller's capabilities and setup nuances.
Hi there! It's not necessary for both PLC controllers to have the identical model and revision number. What's important is that they speak the same data communication protocol. Different PLC models can still communicate provided they are configured correctly, but the process might be easier and more straightforward if you're using identical models. That said, it's always a good idea to refer to the manufacturer's guidelines regarding PLC compatibility and communication.
Hey there! While it's not strictly necessary for both PLC controllers to be the same model or revision, having compatibility between them is crucial for seamless communication and functionality. Different models or revisions might have variations in firmware or tag handling that could complicate your setup. It's always a good idea to check the documentation for both controllers to ensure they can interact properly, even if they're not identical. Good luck with your project!
Hey there! Welcome to the forum! No, it's not strictly necessary for both PLC controllers to be the same model or revision number, but Iād recommend ensuring that they are compatible in terms of their communication protocols and software capabilities. Different models might handle produced and consumed tags differently, so checking the manufacturer's documentation for any compatibility notes is a good idea. It can save you a lot of headaches down the line. Good luck!

Answer: Answer: No, it is not necessary for both PLC controllers to have the identical model and revision number when setting up produced and consumed tags. As long as the controllers support the same communication protocol and can exchange data effectively, they can communicate with each other.
Answer: Answer: When setting up produced and consumed tags, factors such as communication protocol compatibility, data exchange requirements, network configuration, and programming logic should be considered to ensure successful data exchange between the controllers.
Answer: Answer: While it is possible to connect PLC controllers with different models for produced and consumed tags, it is important to verify compatibility and ensure that the controllers can communicate effectively. Some advanced features or functionalities specific to certain models may not be supported when connecting different controllers.
