4. Case study

In this segment we will see how PLCs are incorporated to control various activities in an industry. In this illustration we have a conveyer belt run with two motors at its ends, three different stations to perform various activities like painting of vehicle body or fitting of any component in chassis etc along with two switches to run conveyer. Figure 3.3.4 shows the photograph of a conveyor belt system. The PLC is of “Bull 1764 Micrologix 1500 LSP Series C” which can be controlled by a Graphical User Interface “ RS Logic 500 Starter”.
