IMPLEMENTATION OF A ROBOTIC CONVEYOR ASSEMBLY LINE WITH VISION CAMERA USING TWO DIFFERENT CODING TECHNIQUES AND COMPARISON OF THEIR PERFORMANCE PARAMETERS

In present times, for many automation industries in the light of highly, competitive and volatile markets, it has become necessary to introduce modularity, flexibility, interchangeability and high degree of modification in the manufacturing process. Hence, often there is a dilemma among control engineers regarding the type of programming style for Programmable Logic Controller (PLC), which usually controls the entire system, should be adopted in accordance to the given setup. In this paper, we demonstrate and compare the performance parameters of the two most commonly used PLC coding techniques, Ladder Logic and Step Logic, for an ideal process control setup. This example can be taken as a reference example for any programmer who confronts a similar situation.
