See the following note:
Example:
If the average values of the harmonics of the voltage at the phases a, b, and c must be read, 3 requesting te-
legrams must be sent. Each of these telegrams contains the register range entered for these values (or a part
of it) for phases a, b, and c.
In SICAM PQS, the user must define different corresponding requesting groups for this, for example:
Figure 2-5 Settings in SICAM PQS
NOTE
For the access to measured values, the measured values read with a telegram must be exclusively in this ran-
ge. The addressed address range in a requesting telegram must not exceed the register range or fall below
this range.
