Sequence Control Instructions Section 3-5
The following table shows the treatment of various outputs in an interlocked
section between IL(002) and ILC(003).
Note 1. These instructions are supported by the CJ1-H-R CPU Units only.
2. Bits and words in all other instructions including TTIM(087), TTIMX(555),
MTIM(543), MTIMX(554), SET, RSET, CNT, CNTX(546), CNTR(012), CN-
TRX(548), SFT, and KEEP(011) retain their previous status.
If there are bits which you want to remain ON in an interlocked program sec-
tion, set these bits to ON with SET just before IL(002).
It is often more efficient to switch a program section with IL(002) and
ILC(003). When several processes are controlled with the same execution
condition, it takes fewer program steps to put these processes between
IL(002) and ILC(003).
The following table shows the differences between IL(002)/ILC(003) and
JMP(004)/JME(005).

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
outputs 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.
