Abstract: 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.
