1 GENERAL DESCRIPTION
(2) Program development efficiency is enhanced by dividing control into parts
The machine control process can be divided into parts by describing the operation sequence
and machine control separately. The MELSAP-L is used to describe the operation sequence
for the machine, and a sequence program (circuit/list) is used to describe the machine control
including individual interlock.
