(1) This instruction is designed to reset the master control and indicates the end of the
master control range.
(2) Do not provide a contact instruction in front of the MCR instruction.
The master control instructions can be nested. Their master control ranges are
differentiated by the nesting (N). The nesting can be used from N0 to N7.
Using the nesting structure, you can create a ladder that restricts the program
execution conditions in order.
The ladder using the nesting structure is as shown below.
