When executing a control target in sequence control, create "Operation memory 1" and create an actual
control program with the condition of "Operation memory 1".
"Operation memory 1"of the actual control program is reset with "Completed PLS 1".
To proceed to the next process, create "Next process PLF", which is a falling signal, to turn off
"Operation memory 1" and start "Operation memory 2".
