The solution was to make the logger object a global variable.

Using "this" as object parameter did not work for me.

Hi, I try to make a logger which hooks a callback on an element of a datapoint type. When I run the query connect from the main function of a test script, it works (the testscript keeps running in the process monitor, status 2): main() { string query = "SELECT '_online.._value' FROM '*.el1.el2'...

Thanks for the response, this is what i was looking for. I will explore the AI Assistant

Hi,

The use of DpConnect() is firing a callback when the value of a datapoint changes. Is there a function or a way to fire a callback when a new datapoint is created for a certian datapoint type?

Kind regards,
Stef

Thank you very much for the answer, works perfectly.
I could not find the _stime attribute in the documentation:

Hi,

I want to read the timestamp of a specific datapoint in control script.
How can I do this?
In the documentation I found a lot of attributes to read with dpget, but I can't seem to find the timestamp of the last write to a datapoint.

Thanks in advance,
Stef
