I would like to add the MK-5 Date and Time to a historian. However, the date and time are not in unitdata.dat. On an HMI, the MK-5 date & time points are cimplicty virtual points but I do not know how the point values are set. Does anyone have a suggestion of how to go about placing the MK-V date and time on a historian since these points do not appear to be in unitdata.dat?

 

Actually it is much easier to ensure that the HMI, MKV, and the historian are synchronized to a time source.

Then events in historian, hmi, and MKV are time stamped the same.
