This program uses the special relay M9040 (ag to prevent the step transfer) to meet the purpose of single-step control.
Users can make good use of this method after understanding it. The two drawings below display using the (a) SFC or
(b) STL in writing the program, in order to comparison reference.

Control the step transfer prevent special relay. It allows step transfer at the
moment X0=ON, to achieve the purpose of single-step control.
When the “Repeat” mode (X1=ON, X2=OFF) is selected, press the START button to execute the operation repeatedly.
When the “Single Run” mode (X1=OFF, X2=OFF) is selected, press the START button to execute a cycle of operation.
