Is it possible to get a point value's last change time and display it on custom page?
Point last change timestamp
On a custom view you can use a scriptPoint tag to access the current timestamp of a point.
Thanks for your answer, Matthew.
But time in scriptPoint is not what I need. It is the time of last point update (at least for MODBUS points), but I need the time when point value changed.
Ah. There isn't a way to get that via an AJAX update, but there should be a way to it if you draw it in JSP. I've never had to do it, so i'm not sure.
