12.8.2 Application
The current and voltage measurements functions (CVMMXN, CMMXU, VMMXU and
VNMMXU), current and voltage sequence measurement functions (CMSQI and VMSQI)
and IEC 61850 generic communication I/O functions (MVGGIO) are provided with
measurement supervision functionality. All measured values can be supervised with four
settable limits, that is low-low limit, low limit, high limit and high-high limit. The measure
value expander block (MVEXP) has been introduced to be able to translate the integer
output signal from the measuring functions to 5 binary signals, that is below low-low limit,
below low limit, normal, above high-high limit or above high limit. The output signals can
be used as conditions in the configurable logic.
12.8.3 Setting guidelines
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).
