Converting monitoring data types
The content under <Root> will convert the IEC 104 data objet to a pivot object as follow:

IEC104 NORTH step:
If the Datapoint configured in the exchanged data has not IEC104 timestamp typeid
Then we create an ASDU with a typeid with no timestamp
If the Datapoint configured in the exchanged data has IEC104 timestamp typeid
Then we create an ASDU with a timestamp typeid, ASDU timestamp = do_ts And subtituted = do_ts_sub
