Name Type Default Description
RANGE INTEGER 0 Measured value range
Table 703: RANGE_XP Output signals
Name Type Description
HIGHHIGH BOOLEAN Measured value is above high-high limit
HIGH BOOLEAN Measured value is between high and high-high limit
NORMAL BOOLEAN Measured value is between high and low limit
LOW BOOLEAN Measured value is between low and low-low limit
LOWLOW BOOLEAN Measured value is below low-low limit
16.8.5 Operation principle
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 704 .
