Automatic Production Lines Model Using Profinet Communication Between Plc Siemens S7-1200s Programmed By Tia Portal

This paper introduces the model of automatic production lines using Profinet connection between Programmable Logic Controllers (PLCs). This model includes four commonly used stations in industrial production lines which are - products assortment station, components attachment station, assembly station, and products storage station. Each station is controlled by a Siemens PLC S7-1214 DC/DC/DC. These stations are directly communicated to each other via Profinet through 2 Ethernet switches CSM 1227 using “star topology”. The PLCs are programmed in TIA Portal software using Function Block Diagram (FBD), Ladder Logic Diagram (LAD), and Structure Control Language (SCL) languages. The model has been tested in practical operation, and it demonstrated the stability of each station as well as the communication process between PLCs. The success of the model allows us to build the completed production lines by assembling their substations to save the time for design and fabrication
