Workstation description
The workstation consists of a trolley that can move in a straight line in two directions. The position of the trolley is detected at four points located symmetrically in relation to the center of the system.

Description of the project operation (attached control program)
The control program’s task is cyclical movement of a trolley between the positions determined by the limit sensors. In addition, the speed of the trolley's movement is reduced between the middle and limit sensors.
Control
![]() |
The project offers two modes of control. You can switch between them by the 'auto / manual' button (0 - automatic, 1 manual): - manual mode, in which we decide with the 'left / right' bistable button whether the trolley should go left or right. The trolley stops at the positions determined by the limit position sensors. The speed is automatically reduced in the sections between the middle and limit position sensors. - automatic mode, starting the control program embedded in the PLC controller using the 'START' button and stopping it with the 'STOP' button (the buttons operation must be implemented within the control program on the PLC controller) |
Description of the PLC inputs / outputs
Y0 - trolley moves to the right
Y1 – trolley moves to the left
Y2 - speed reduction
X0 - START button
X1 - STOP button
X2- position sensor 1 (left limit)
X3- position sensor 2 (left middle)
X4- position sensor 3 (right middle)
X5- position sensor 4 (right limit)
Description of the inputs / outputs can also be found on the project diagram in the place marked below.
