Elevator 34-150

The elevator provides a sophisticated application to illustrate the principles of PLC interfacing and control based on a real life application. Starting with simple programme sequences to control elevator speed, direction and floor arrival/departure, the student can progress to advanced floor request handling and continuous (analogue) control with acceleration profiling and compensation for varying car loads.
