Workstation description
A workstation with three actuators equipped with proximity switches activated by a ball moved by actuators. A very simple industrial automation system. 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.
Mathematical model:
PLC inputs:
X0 - START button
X1 - actuator 1 end position - piston rod extended
X2 - actuator 2 end position - piston rod extended
X3 - actuator 2 end position - piston rod retracted
X4 - actuator 3 end position - piston rod extended
X5 - actuator 3 end position - piston rod retracted
X6 - sensor 1 (detecting the ball in the home position)
X7 - sensor 2 (detecting the presence of the ball on a lift)
PLC outputs:
Y0 - extension of piston rod 1
Y1 - extension of piston rod 2
Y2 - extension of piston rod 3
