Sequence Control Instructions
Section 3-5
The MILH(517)/MILR(518) instruction turns OFF the Interlock Status Bit
(operand D) when the interlock is in engaged and turns ON the bit when the
interlock is not engaged. Consequently, the Interlock Status Bit can be moni-
tored to check whether or not the interlock for a given interlock number is
engaged.
Nesting
Interlocks are nested when an interlocked program section (MILH(517)/
MILR(518) and MILC(519) combination) is placed within another interlocked
program section (MILH(517)/MILR(518) and MILC(519) combination). Inter-
locks can be nested up to 16 levels.
Nesting can be used for the following kinds of applications.
• Example 1
Interlocking the entire program with one condition and interlocking a part
of the program with another condition (1 nesting level)
• A1 and A2 are interlocked when the Emergency Stop Button is ON.
• A2 is interlocked when Conveyor RUN is OFF.
