32GB Card Not Seen by V1.8 1500s

I have a 32GB memory card (6ES7954-8LT02-0AA0) that was working 100% with a 1516F running firmware 1.7.  I then upgraded the firmware to V1.8.3 via the online interface in TIA Portal, and the card instantly was no longer recognized by this CPU or any other 1500s.  I get the error 0002:4175 "Memory card evaluation error: Memory card not accepted or cannot be mounted - Function finished/aborted, new startup inhibit set: - Memory card missing, wrong type, wrong content, or protected."

When I plug the card into the PG's card reader, I can see the card contents in TIA Portal and Windows Explorer, so it's still functioning.  I never removed the card before/during the upgrade, so no pins were bent.  I can plug other cards into the processors no problem, but it's just this one that doesn't work.

I tried clearing the contents by dragging an empty project onto it and also by deleting the .s7 folder in Windows Explorer, but it's still not recognized on the processors.  I have also tried changing the card to a firmware upgrade card and back to a project card, and nothing changed.

Unfortunately, I have no V1.7 processors, so I can't verify its functionality with V1.7 processors currently.

Any ideas on why this card stopped working?

 Hello,

Perhaps the following topic might help:

How do you detect an inconsistently or incorrectly formatted SIMATIC Memory Card (SMC) and how do you repair it?

• Event: "Error when evaluating memory card: Load memory not accepted..."
• Event ID: "16#02:4175"
• Description: "CPU error: Error when evaluating memory card: Load memory not accepted or cannot be created, current card type: Memory card incorrectly formatted ..."

Restore memory card with S7-1500
 

 Thanks for the idea.  I had read through that and tried already.  I had to run a chkdsk /f from the Command Prompt since that window never popped up for me, but nothing changed.   I can obviously only do it via Windows, since when I try to format via TIA Portal, it fails since the 1500 can't detect the card.

chkdsk returned "Windows has checked the file system and found no problems."

No.	Procedure
1	Slot the SIMATIC Memory Card into a standard card reader.
2	Windows 7 automatically checks whether the card was removed correctly by the last user (bit with boot sector).
3	The "Do you want to check and repair "SIMATIC MC"?" dialog opens.
4	Click "Check and repair (recommended)".
5	Click "Start".
6	The card is now repaired.
7	Close the dialog box.

Restore memory card with S7-1500
 

No.	Procedure
1	Slot the SIMATIC memory card into an S7-1500 CPU.
2	Establish an online connection with a PG/PC (STEP 7 V12) and S7-1500 CPU.
3	Open the "Online & Diagnostics" view of the CPU.
4	In the "Functions" folder you select the "Format Memory Card" group.
5	Click the "Format" button

You could downgrade the firmware again and try if it works: https://support.industry.siemens.com/cs/ch/de/view/92274475

 That ended up working, thanks.

I did some testing, and the card is only compatible with firmware version 1.7.  Versions 1.8.1-1.8.3 all give me the same error.  Very strange.

Maybe you just discovered a compatibility problem between 1.7 and 1.8.x. If you would contact Siemens the problem could be analyzed in detail. Of course they would need your memory card content.

But it seems you need to stick to 1.7 or migrate to 1.8.x via a new download into the PLC. Before the download I would recommend to delete all project data from the memory card or maybe to format the memory card. This should work without a need to recompile the project. However your configuration would still contain a V1.7 PLC. I assume this step would repair your memory card problem.

Alternatively or in a second step you may consider changing the configured PLC from 1.7 to 1.8 then recompile and then download so that you would be able to use new features of V1.8.x.
