N: Interlock Number
The interlock number must be between 0 and 15. Match the interlock number of the MILH(517) (or
MILR(518)) instruction with the same number in the corresponding MILC(519) instruction.
The interlock numbers can be used in any order.
D: Interlock Status Bit
• ON when the program section is not interlocked.
• OFF when the program section is interlocked.
When the interlock is engaged, the Interlock Status Bit can be force-set to release the interlock. Con-
versely, when the interlock is not engaged, the Interlock Status Bit can be force-reset to engage the
interlock.
