Workstation description
A workstation with one actuator equipped with two limit switches active in extreme positions is one of the simplest, basic industrial automation systems. With its help, you can get acquainted with the basics of writing programs for a PLC controller, including the control of the actuator coils, reaction to signals from limit switches, as well as timers and counters.
The described device model is a ready-made example that can be used directly for educational purposes. The model does not need to be modified, but it can also be freely adapted to your needs. It is adapted to be connected to a PLC simulator or to work with a real PLC controller.
