If there is an ILC(003) instruction between an MILR(518) and MILC(519) pair,
the ILC(003) instruction will be ignored and the full program section between
MILR(518) and MILC(519) will be interlocked.
If there is another MILH(517) or MILR(518) instruction with the same interlock
number between an MILH(517) and MILC(519) pair and the first MILH(517)
instruction’s interlock is engaged, the second MILH(517)/MILR(518) will not
operate.
If there is another MILH(517) or MILR(518) instruction with the same interlock
