(1) Definition
Nesting devices are used to nest MC or MCR master control instructions when
programming operating conditions.
(2) Designation method with master control
The master control instructions are used to open and close the ladders' common

program.
Nesting devices must be numbered in descending order (from N0 to N7) of
nested relation.
