Corrupted Variable Link

What does TSM_E_CORRUPTEDLINK mean?

The specified variables cannot be unlinked, possibly due to a corrupted or invalid link definition in the TwinCAT configuration (0x98510005). This indicates an issue with the integrity of the variable linkage data within the system.

• The link to a PLC variable or an external data source is broken.
• A pointer in the control logic is corrupted or points to invalid memory.
• Network communication issues have disrupted the data link.

Click steps to track your progress.

1. 1

   Verify the bstrV1 and bstrV2 path names accurately identify the linked variables.

2. 2

   Attempt to manually unlink the variables using the TwinCAT System Manager to diagnose the issue.

3. 3

   If the link appears valid, consider recreating the configuration section containing these variables or the entire project if widespread corruption is suspected.
