supervised with four settable limits: low-low limit, low limit, high limit and high-
high limit. The measure value expander block (RANGE_XP) has been introduced
to enable translating the integer output signal from the measuring functions to 5
binary signals: below low-low limit, below low limit, normal, above high limit or
above high-high limit. The output signals can be used as conditions in the
configurable logic or for alarming purpose.

14.8.5 Operation principle
SEMOD52462-4 v5
The input signal must be connected to a range output of a measuring function block
(CVMMXN, CMMXU, VMMXU, VNMMXU, CMSQI, VMSQ or MVGAPC).
The function block converts the input integer value to five binary output signals
according to
table 436.
