Hello, I'm fairly new to this but we just upgraded from our 1769-l32e to the latest 5069-L320erm PLC model. After transferring the file, I ran a Verify on the Controller and encountered an error message "Error: Rung 0, CPS, Operand 0: Invalid member specifier." I'm unsure of the next steps to get the new PLC up and running. Any assistance on resolving this issue would be greatly appreciated. Thank you.
The newer model appears to lack a corresponding "Data" tag, requiring each bit to be mapped individually at the destination. It is necessary to align the bits up to 15OG for proper data transmission.
As OG pointed out, in the 1769 module, all inputs were contained in a single INT tag 'Data', whereas in the 5069 module, each input is its own channel with separate BOOL for data. Unfortunately, there doesn't seem to be a built-in method to map all inputs in a single instruction like before, unless you create your own Add-On Instruction (AOI). This difference in handling inputs may require some adjustments in your programming approach.
I will attempt to individually map out Operaghost and plvlce and test the system. Thank you for your help!
Unfortunately, I am not familiar with a method to efficiently map all inputs in a single instruction as was possible before. It seems Rockwell has introduced changes that make this process more challenging.
KuulKuum expressed frustration over Rockwell's tendency to make future advancements unnecessarily complicated. Despite the introduction of new features, some may argue that they are unnecessary and only cause added difficulty.
Hi there, I'm guessing the inconsistent tag structure between the old and new PLC models may be causing this error message. In the newer CompactLogix series, including your 5069-L320ERM, the tag structure needs defining before referencing it in the program. This is different than older models, like the 1769-L32E where it was not necessary. Ensure your tags have the proper structure defined before use and this should solve your issue. Also, remember to check that all firmware is compatible and updated too, this will help you dodge other potential problems later on. Good luck!
Hi there! It sounds like the code you're trying to transfer contains an instruction or operand that's incompatible with the new controller. The error message suggests that there's an issue in the beginning of your program (Rung 0), especially associated with the CPS instruction. What I would recommend is to open up your program, go to rung zero and examine closely the CPS operation. Check if the operand aligns with what's acceptable for your new 5069-L320erm model. Fix any discrepancies and try rerunning the verification. Additionally, always make sure you're using the latest programming software compatible with your new PLC.
Hey there, it seems like you might be dealing with a conversion issue between the old and new PLC models. This error is usually tied to a command that was used in your 1769-L32E that is no longer applicable or formatted differently in the 5069-L320ERM. My suggestion would be to look for the CPS instruction on Rung 0 in your program and check if you're referencing a correct object or not. If that doesn't resolve it, try reprogramming that specific part in the language of the 5069-L320ERM. Going through Rockwell's conversion reference guide can also be helpful - they walk you through known issues that can happen when transitioning between certain models. Best of luck!
Welcome to the forum! It sounds like you're making a big leap with that upgrade. The "Invalid member specifier" error typically suggests that there might be a mismatch in the programming or the way your tags are configured between the two PLCs. Double-check your tag definitions to ensure they’re compatible with the 5069-L320ERM. Also, if you’re using any advanced features or specific instructions, make sure they are supported on the new PLC model. It might also help to look at the migration documentation from Rockwell for any additional adjustments. Good luck, and don't hesitate to ask if you have more questions!
Welcome to the forum! It sounds like you're dealing with a common issue when transferring programs between different PLC series. The error message you're seeing typically indicates that there's a reference in your program that isn't compatible with the architecture of the new 5069-L320ERM. Double-check any tags or instructions that might not have been updated during the transfer, especially if you were using any specific data types or structures from the 1769 series. It might also help to look through the documentation for the new model for compatibility notes, or consider creating a fresh project and manually transferring the logic to see if that resolves the issue. Good luck, and feel free to reach out if you need more help!

Answer: 1. What does the error message "Error: Rung 0, CPS, Operand 0: Invalid member specifier" indicate when upgrading from 1769 to 5069 PLC model? - This error typically indicates a card mapping issue during the upgrade process from the 1769 to 5069 PLC model. It points to a problem with specifying a member within a data structure, which needs to be addressed for the new PLC to function correctly.
Answer: - To troubleshoot this error, you may need to review and adjust the card mapping settings for the new 5069 PLC model. Verify that the data structures and member specifiers in your program match the configuration of the new PLC hardware.
Answer: - First, carefully review the card mapping settings to ensure compatibility with the new 5069 PLC model. Check for any discrepancies in data structure definitions and member specifiers between the old and new PLC models. Make necessary adjustments and re-verify the program to resolve the error.
Answer: - Yes, you can refer to the user manuals, technical guides, or online resources provided by the manufacturer for guidance
