Range High Limit or Direct Write Value
(Range12To15[n].HiLimOrDirWr)
This value can be used in one of two ways, depending on the setting of the Load
Direct Write (Range12To15[
n].LoadDirectWrite) bit.
When Load Direct Write = 0
When Range12To15[
n].LoadDirectWrite = 0, then
Range12To15[
n].HiLimOrDirWr is used in the range comparison (range
represents a count value or a rate value according to the programmed range type,
Range12To15[
n].Type).
When the range value is equal to Range12To15[ n].HiLimOrDirWr, Rangen will
change state. The range will become active or inactive depending on the
Range12To15[
n].Invert bit.
IMPORTANT For the L23E packaged controllers embedded HSC, the ranges referred to
in this section are numbered 0…3 instead of 12…15. The ranges in this
section apply to only the 1769-HSC module and the CMX 5370 L2
packaged controllers embedded HSC.

TIP Range12To15[n].HiLimOrDirWr must be higher than the
Range12To15[n].LowLimit or the InvalidRangeLimitn error flag in the
input array will be set.
TIP Range12To15[n].HiLimOrDirWr can be higher than the maximum rate or
count value. For example, when the object value is a rate,
Range12To15[n].HiLimOrDirWr can be programmed in excess of
1,000,000 with no configuration error.
