Siemens PLC Programming Example Rail Travels Between Points

Siemens PLC Programming Example

The load carrier on a rail travels between two points. This work, which is carried out by changing the direction of rotation of a motor, is started with a start button. When the trolley reaches the forward or back end point, it moves in the other direction without stopping.

Pressing the stop button at any time does not stop the engine immediately. After the stop is pressed, the trolley stops when it reaches the limit switch in the direction it travels.

If we want to stop the engine wherever the trolley is, it is necessary to press the stop button simultaneously with the start.
