task and program number if necessary.
Program Flow Turn ON input R1 to specify automatic mode.
Turn ON input R2 in the following situations:
• The first time that the program is executed after the power is turned ON.
•
When executing the program from the beginning.
• When the program number has been changed.
Execution of the MC program will begin when R4 goes ON.
