7.
Sample Task Press Control
For our first program, we are programming a press control.
A press with a protection device can only be started with a START button S3 when the protection grid is
closed and the EMERGENCY STOP button (NC contact) is not operated. The state Protection grid
closed is monitored with a sensor B1.
If this is the case, a 5/2 way valve M0 is set for the press cylinder to press a plastic figure.
The press is to power up again when the start button S3 is operated, the EMERGENCY STOP button
(NC contact) is operated or the sensor Protection grid B1 no longer responds.
