Settings

The function does not have any parameters available in Local HMI or Protection
and Control IED Manager (PCM600).
Common base IED values for primary current (IBase), primary voltage (UBase)
and primary power (SBase) are set in a Global base values for settings function
GBASVAL. Setting GlobalBaseSel is used to select a GBASVAL function for
reference of base values.

Operation principle

The input signal must be connected to a range output of a measuring function block
(CVMMXN, CMMXU, VMMXU, VNMMXU, CMSQI, VMSQ or MVGGIO).
The function block converts the input integer value to five binary output signals
according to table 335.
