Precautions

The cycle time is not shortened when a section of the program is interlocked because the interlocked

instructions are executed internally.

In general, IL(002) and ILC(003) are used in pairs, although it is possible to use more than one

IL(002) with a single ILC(003) as shown in the following diagram. If IL(002) and ILC(003) are not
paired, an error message will appear when the program check is performed but the program will be
executed properly.

IL(002) and ILC(003) cannot be nested, as in the following diagram. (Use MILH(517)/MILR(518) and

MILC(519) when it is necessary to nest interlocks.)

If there are bits which you want to remain

ON in an interlocked program section, 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).
