Figure 26: Split Range And Sequence Operation - Honeywell SLG 700 Option Manual

The examples shown do not show the full range of possibilities. The lines could overlap like an X, or
both start from the origin but have different slopes. The endpoints do not have to lie within 0-100%.
Limits in the external blocks may affect the useful range of a line. Units of percent are used in the
examples because the common application of this block is to valves, but any units may be used to suit
the application.
The following parameters may be used to specify the output splitter operation:
X11, Y11, X12, Y12
X21, Y21, X22, Y22
Where XnJ is the value of SP associated with OUT_n and Xn1 and Xn2 refer to the 1st and 2nd
coordinates of the nth curve respectively. YnJ is the value of OUT_n and Yn1 and Yn2 refer to the 1st
and 2nd coordinates of the nth curve respectively.

By specifying the coordinates as shown above, the endpoints of the lines are defined. The contents of
the respective X's are held in the IN_ARRAY parameter and the contents of the respective Y's are
held in the OUT_ARRAY parameter. If a set of points are specified such are held in the IN_ARRAY
parameter and the contents of the respective Y's are held in the OUT_ARRAY parameter. If a set of
points are specified such that a region of the input range is not specified, then the corresponding
OUT_n may be set to the closest endpoint of the input value, either high or low, when the specified
region is exceeded.
