The student … Mechanics assembles and disassembles mechanical components interfaces mechanical systems

• Interfaced workstations controlled by PLCs For the control tasks at least two stations should be interfaced Example of a control tasks using 2 stations The distribution station of a production line is feeding work pieces into a testing station. The PLCs, sensors and actuators of both stations are linked over bus system networks. Distributing Station Task The distributing station is separating work pieces from a magazine and feeding them into a process (Testing station) Design Stack magazine Pneumatic acting cylinder Valves Vacuum generator PLC control / digital inputs Testing Station Task The testing station receives the work pieces and recognizes different materials and carries out quality control of the work pieces Design
