Sequence Control Instructions Section 3-4
Examples When CIO 0.00 is OFF in the following example, all outputs between IL(002)
and ILC(003) are interlocked. When CIO 0.00 is ON in the following example,
the instructions between IL(002) and ILC(003) are executed normally.
3-4-5 MULTI-INTERLOCK DIFFERENTIATION HOLD, MULTI-INTERLOCK
DIFFERENTIATION RELEASE, and MULTI-INTERLOCK CLEAR:
MILH(517), MILR(518), and MILC(519)
Purpose Interlocks all outputs between MILH(517) (or MILR(518)) and MILC(519)
when the execution condition for MILH(517) (or MILR(518)) is OFF. MILH(517)
(or MILR(518)) and MILC(519) are normally used in pairs.
Unlike the IL(002)/ILC(003) interlocks, the MILH(517)/MILC(519) and
MILR(518)/MILC(519) interlocks can be nested. The operation of differenti-
ated instructions is different for interlocks created with MILH(517) and
MILR(518).
