Time-of-day synchronization and time stamp
The AI Energy Meter HF supports time-of-day synchronization and time stamp.
Time stamps are used to date the exact occurrence of information. You can find time
information in the measured value data records "Measured value data record for maximum
values with time stamp (DS 154)" and "Measured value data record for minimum values with
time stamp (DS 155)", for example, or the power quality analysis data records DS160,
DS161 and DS163. For the time on the AI Energy Meter HF to correspond to the current
system time, the clock must be synchronized externally. Information on this and additional
requirements can be found in the application example
(http://support.automation.siemens.com/WW/view/en/109754890
). In the absence of time-of-
day synchronization, the internal time stamp of the AI Energy Meters HF starts at
01.01.1970, 0:00.
