TTIMX(555), MTIM(543), and
MTIMX(554))
For example, an MILH(517) instruction cannot be inserted between IL(002)
and IL(003).
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.
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).
Treatment in IL(002)/ILC(003), MILH(517)/
MILC(519), or MILR(518)/MILC(519))
Instructions other than OUT, OUT NOT,
OUTB(534), and timer instructions are not
executed.
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.
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.
