Study and Application of the IO-Link Industrial Network in the Context of Industry 4.0.

This study presents the concepts, definitions and applications of IO-Link System, highlighting its main characteristics, its implementation, rates of transmission and protocol. We have used the IEC 61131-9 standard as the main reference which considers IO-Link as the first I/O technology for communication with sensors and actuators as an international standard. We also discuss, as a case study, its use on a company dedicated to packaging machinery. It reduced the breakdown and downtime of machines by detecting their own maintenance needs before a failure occurs, thus improving productivity.
