Hi Russ,
no, you are not missing something, it is not available, but has been added to the requirement specification (change event for persistent variables; as far as I know for datatypes string, bool and num).
A workaround would be subscribing to signal change events (virtual signals should work, too).
the release version should be ready next week or so. Since I’m outside ABB I cannot download any version, but the current FlexPendant SDK beta is very stable.
