Module Configuration, Output, and Input Data Chapter 4

When Load Direct Write = 1

When Range12To15[n].LoadDirectWrite = 1, then

Range12To15[n].HiLimOrDirWr is used to change the Ctr[n].CurrentCount to

Range12To15[n].HiLimOrDirWr.

When the Range12To15[n].LoadDirectWrite bit transitions from 0 to 1, then

Range12To15[n].HiLimOrDirWr is loaded into Ctr[n].CurrentCount (where n

is the counter indicated in Range12To15[n].ToThisCounter).

Range Low Limit (Range12To15[n].LowLimit)

This value is used in the range comparison. It is the complement of the

Range12To15[n].HiLimOrDirWr value in setting the compare window.

When the rate or count value is equal to Range12To15[n].LowLimit, the range

will change state – opposite of the action at Range12To15[n].HiLimOrDirWr.

The range will become active or inactive depending on the

Range12To15[n].Invert bit.

TIP

When CtrnSoftPreset and a Range12To15[n].LoadDirectWrite to counter

n are indicated at the same time, only the CtrnSoftPreset will occur.

When more than one range indicates a Range12To15[n].LoadDirectWrite

to a single counter, only the one from the lowest designated range will

take effect.

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.

Output Array Words 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00

12 and 13 Range 12 Low Limit Range12To15[0].LowLimit

18 and 19 Range 13 Low Limit Range12To15[1].LowLimit

24 and 25 Range 14 Low Limit Range12To15[2].LowLimit

30 and 31 Range 15 Low Limit Range12To15[3].LowLimit

TIP

Range12To15[n].LowLimit must be lower than the

Range12To15[n].HiLimOrDirWr or the InvalidRangeLimitn error flag in the

input array will be set.

TIP

Like Range12To15[n].HiLimOrDirWr

Range12To15[n].LowLimit can extend beyond the minimum rate or

count value.

TIP

When Range12To15[n].LoadDirectWrite is set, Range12To15[n].LowLimit

is ignored.
