Hi,

I correctly implemented the SaveRetain variables using the project example provided in this forum (link: viewtopic.php?t=5722#p10428).
All works perfectly.

I'm wondering if there is a method to know if one of the persistent variables have been changed so I can trigger the save flag to store the retain area into the SD file.

Is it possible?
