is it possible to save/export retain value from ac800m in a CCB project
There are tools (like start value analyzer) that can collect cold retain values and reatin values to a text file which can be imported to exel sheet. But Im not sure if these tools can be distributed outside freely. Theya are generally part of Service products.
Please contact ABB support center for more information on them.
Basically you can collect values, analyze the differences between two collected versions etc using these tools.
Also please refer earlier answer regarding this..
