The use of the control panel is similar to most facilities with cyclic motion. For this reason it is important know how it is programmed.

Write a cyclical control program for the three cylinders by using the inputs (Start, Stop, Automatic/manual, Acknowledge) and outputs (Initial position, Stop, Q1, Q2) of the control panel.

  • 6 sensors for detecting the end position of the cylinders
  • Four inputs of the control panel (Start, Stop, Reset and Auto/Man switch)
  • 3 pushbuttons in the user interface
  • 1 switch
  • 3 actuators for operation of the valves
  • 4 lamps indicating status
