MILH/MILR/MILC
• Program operation can be switched more efficiently by using interlocks with MILH(517) or MILR(518).
Instead of switching processing with compound conditions, insert an MILH(517) or MILR(518)
instruction before each process and an MILC(519) instruction after each process.
• Unlike the IL(002) interlocks, MILH(517) and MILR(518) interlocks can be nested, so the operation of
similar programs will be different if MILH(517) or MILR(518) is used instead of ILC(002).
• Program with MILH(517)/MILC(519) Interlocks
• 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.
