After the TIA Portal was upgraded from V15.1 to V16, an error occurred when downloading the recipe and the action terminated abnormally.

1. There is no problem when reading the recipe, it is completely normal and there is no error message.

2. But when downloading, it prompts "Error. Action terminated abnormally"

Based on past experience and analysis, there may be a download error when there is no corresponding address in the recipe variable, but there is a gray prompt in the corresponding place on the recipe screen, but there is no such thing.

I also thought that the variable address was wrong, so I changed the address of the variables to absolute addresses one by one, and still got an error.

Finally, I considered whether the variable name was too long, causing the problem, and shortened the variable name, but it still didn't work.

In the end, there was really no other way to turn to the Siemens VIP hotline. After receiving guidance from the Siemens hotline, it was found in the alarm record that the variable range exceeded the limit, resulting in the inability to download.
