I am in the process of upgrading to a 504 CPU, and encountering a 9028 error on my HMI. Could someone clarify what is meant by the need to "change reference"?
Do you know the part number of your PanelView and the type of communication you are using? Is this for a new installation or a system that has been operational previously? Let us help you determine the compatibility of your PanelView and communication requirements.
I believe I own a 2711-k6c1 B revision K with FRN 4.21, and my communication settings are configured for DH+ connectivity.
While the K6C1 does offer support for RIO, it does not support DH+ network. For more information, refer to page 20 of the user manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/2711-um014_-en-p.pdf Could this possibly be for a recent installation?
In order to operate the PanelView effectively, ensure a 174-SN card is inserted in the rack. It is important to note that DH+ and RIO may use the same communication cable, but they function on separate protocols.
I possess a 1747-SN Series B module commonly used in industrial automation systems.
It seems like the "change reference" message could be referring to an issue with your reference memory addresses. In this context, when you upgrade or change components, the CPU may need you to remap memory locations. Basically, it needs to know where to find or store data in the new setup. Hence, it would be best to check your system's schematics or documentation for this. Tools like memory-mapped IO would also come in handy.
The "change reference" message typically implies that there's an issue with how your HMI is referencing your CPU's data. It's a mismatch of sorts - perhaps your system's pointers are interacting with obsolete or incorrect data locations. This could be due to the upgrade, as certain addresses may have changed. I'd recommend double-checking your reference tables against the CPU's documentation to make sure everything matches up correctly.
The 9028 error in the HMI typically indicates an issue with how the system references variables in your code. When suggested to "change reference", it generally means that you may need to adjust the variable names or data types in your code that your HMI is interfacing with. This is essentially to ensure consistency between your HMI and CPU, avoiding any discrepancies that may cause errors. It might be tedious but thoroughly worth the troubleshooting.
"Changing reference" usually refers to altering the index or address from which the CPU or HMI is reading data. In this case, your 9028 error may indicate that your HMI is trying to retrieve data from a memory address that doesn't exist or is invalid. To fix this, you may need to locate the reference in your code that's causing issues and change it to a valid address or index. However, without seeing the specific system setup or code, it's a bit difficult to provide a more precise solution.
It sounds like you're on the right track with your upgrade! The "change reference" message usually indicates that the new 504 CPU is looking for different data mapping or I/O references than what your old setup used. Essentially, your HMI may be referencing tags that no longer exist or have changed in your new configuration. It might be worth double-checking your HMI tags and updating them to align with the new CPU’s data structures. Good luck with the transition!
