Description

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.
OFF
Reset
Interlocks all outputs between IL(002) and ILC(003) when the execution con-
dition for IL(002) is OFF. IL(002) and ILC(003) are normally used in pairs.

Not allowed
When the execution condition for IL(002) is OFF, the outputs for all instruc-
tions between IL(002) and ILC(003) are interlocked. When the execution con-
dition for IL(002) is ON, the instructions between IL(002) and ILC(003) are
executed normally.
