Sequence Control Instructions Section 3-4
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.
Differences between
Interlocks and Jumps
The following table shows the differences between interlocks (created with
IL(002)/ILC(003), MILH(517)/MILC(519), or MILR(518)/MILC(519)) and jumps
created with JMP(004)/JME(005).
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.

Instruction execution Instructions other than OUT, OUT NOT,
OUTB(534), and timer instructions are not
executed.
No instructions are executed.
Output status in instructions Except for outputs in OUT, OUT NOT,
OUTB(534), and timer instructions, all out-
puts retain their previous status.
All outputs retain their previous status.
Bits in OUT, OUT NOT,
OUTB(534)
OFF All outputs retain their previous status.
Status of timer instructions
(except (TTIM(087),
TTIMX(555), MTIM(543), and
MTIMX(554))
Reset Operating timers (TIM, TIMX(550),
TIMH(015), TIMHX(551), TMHH(540),
TMHHX(552) only) continue timing because
the PVs are updated even when the timer
instruction is not being executed.
