Precautions
• Up to 15 nests (N0 to N14) are allowed. When nesting is performed, the MC instruction should use nesting (N) numbers in
order from lower numbers and the MCR instruction should use them in order from higher numbers.
• If the MCR instructions are nested in one place, all master controls can be terminated by specifying the lowest nesting (N)
number.
