Hello tulip;

SFC1 will read the Real-Time Clock of your processor:

The tag that you will use to write the CDT output to must be formated as a Date_and_Time variable.

Here is (from a preceding thread) the way the info is distributed inside the Date_and_Time variable:

Hope this helps,

You can use this function if you have any problems extracting the components from the DT variable:
