12.13.5 Settings
The function does not have any parameters available in Local HMI or Protection and
Control IED Manager (PCM600).
GlobalBaseSel: Selects the global base value group used by the function to define (IBase),
(VBase) and (SBase).
12.13.6 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 405.
