The Programmable Logic Controller (PLC) is widely used in industries to control a mechanical movement for an efficient production. The paper presents modelling of PLC based system to automate material handling process in industries. In the proposed system the packages are sorted out with the help of scanners and stamp it if the package is correct and then stack it. The simulation studies of the modelled system for various sections such as filling, sorting, packaging, stamping and loading are

... o presented in the paper. It is found that the developed system may substitute the human labour involved and thus reduce the time consumption and human errors in handling of materials in industries. The stamping and sorting is done with the help of human labour in most of the industries.
