Sequence Control Instructions
Section 3-5
Differences between
MILH(517) and MILR(518)
Differentiated instructions (DIFU, DIFD, or instructions with a @ or % prefix)
operate differently in interlocks created with MILH(517) and MILR(518).
The operation of differentiated instructions in an interlock created with
MILH(517) is identical to the operation in an interlock created with IL(002).
For details, refer to
3-5-5 MULTI-INTERLOCK DIFFERENTIATION HOLD,
MULTI-INTERLOCK DIFFERENTIATION RELEASE, and MULTI-INTER-
LOCK CLEAR: MILH(517), MILR(518), and MILC(519)
.
Precautions
Do not combine interlocks created with different interlock instructions (IL-ILC,
MILH-MILC, and MILR-MILC). The interlocks may not operate properly if dif-
ferent interlock methods are used together. For details on combining instruc-
tions, refer to
3-5-5 MULTI-INTERLOCK DIFFERENTIATION HOLD, MULTI-
INTERLOCK DIFFERENTIATION RELEASE, and MULTI-INTERLOCK
CLEAR: MILH(517), MILR(518), and MILC(519)
.
For example, an MILH(517) instruction cannot be inserted between IL(002)
and IL(003).
Note
The different interlocks (IL-ILC, MILH-MILC, and MILR-MILC) can be used
together as long as the interlocked program sections do not overlap.
For example, all three interlock methods can be used without overlapping, as
shown in the following diagram.
IL
MILH
ILC
MILH(517) is in an interlocked area
between IL(002) and ILC.(003).

Different interlock methods can be
used as long as the interlocked
areas do not overlap.
