The control structure is mainly based on three sections:
– The SIPLACE-LAN being the interconnection between line computer and every single station
computer and machine controller of the whole line.
– The axis controlling responsible for any axis movement and input / output function in the ma-
chine.
– The vision system measuring the components and fiducials below the cameras.
