Function
The master control instruction is used to enable the creation of highly efficient ladder switching sequence programs, through
the opening and closing of a common bus for ladders.
A ladder using the master control is as follows:
Remark
Inputting of contacts on the vertical bus is not necessary when programming in the write mode of a peripheral device.
These will be automatically displayed when the "conversion" operation is conducted after the creation of the ladder and
then "read" mode is set.
