Sequence Control Instructions Section 3-4
Program with IL(002)/ILC(003) Interlocks
If there are bits which you want to remain ON in a program section interlocked
by MILH(517) or MILR(518), set these bits to ON with SET just before the
MILH(517) or MILR(518) instruction.
Flags
Precautions The cycle time is not shortened when a section of the program is interlocked
by MILH(517) or MILR(518) because the interlocked instructions are executed
internally.
