Development of Test Jig for PLC and Programming for Commonly Used Blocks

Abstract

Automation is basic requirement in industrial development. Programmable Logic Controller (PLC) plays an important role in development of industrial automation. PLC have many I/O pins that can be used for controlling various applications. There are some expandable modules in PLC for controlling applications. User can expand up to 8 expansion. To develop test jig for testing Flexi Logic PLC series is the main objective of this project. By developing Automatic Test Equipment (ATE) for PLC, it is possible to minimize and remove the human intervention. This can provide efficient and faster testing of equipment. Development of Common Ladder Programming (CLP) is nothing but combine frequently used ladder blocks so that user can easily identify the absent ladder network among them and user will add only absent block in that network.
