24.3.2 Application
SEMOD52434-4 v5
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 (MVGAPC) 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 ( RANGE_XP) 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.
24.3.3 Setting guidelines
SEMOD113223-4 v1
There are no settable parameters for the measured value expander block function.

24.4.1 Application
M12007-6 v9
Six sets of settings are available to optimize IED operation for different power system
conditions. By creating and switching between fine tuned setting sets, either from the
local HMI or configurable binary inputs, results in a highly adaptable IED that can
cope with a variety of power system scenarios.
Different conditions in networks with different voltage levels require highly adaptable
protection and control units to best provide for dependability, security and selectivity
requirements. Protection units operate with a higher degree of availability, especially, if
the setting values of their parameters are continuously optimized according to the
conditions in the power system.
Operational departments can plan for different operating conditions in the primary
equipment. The protection engineer can prepare the necessary optimized and pre-tested
settings in advance for different protection functions. Six different groups of setting
