Reading a negative 3 Phase Real Power actual value from the PQM:
4.
Following the method described above:
DATA VALUE = (FF3A
×
2
16
) + EA7B
hexadecimal
= (65338
×
2
16
) + 60027
converted to decimal
= 4282051195
decimal
5.
The most significant bit of the High Order register is set, therefore the DATA VALUE is calculated as:
DATA VALUE = DATA VALUE – 2
32
= 4282051195 – 4294967296
= –12916101
Applying the Units & Scale parameters to the DATA VALUE, we multiply the DATA VALUE by 0.01 kW. There-
fore the resultant value of 3 Phase Real Power as read from the memory map is –129161.01 kW.
