Programming and testing a PLC to control a scalable industrial plant in remote way

This paper presents a scalable industrial plant which puts plug and label to bottles. It is controlled by a commercial programmable logic controller (PLC). To do that, the plant has two conveyor belts. The first one goes from the origin to the place where the plug is put to the bottle and the second one goes from that place to where the label is put (the end of the route). The element which puts the plug is virtual, implemented using augmented reality (AR) techniques, and the labeler is a real element. Moreover, the plant is a combination of real and virtual elements. The presented plant is accessed from internet (both the PLC to be programmed and the plant to test the control program). It has been proposed to make a practical class in several subjects at the University of Huelva.
