In recent years, IO-Link systems have become widespread within industrial automation. IO-Link is an open standard serial communication protocol that allows for the bi-directional exchange of data from IO-Link-supported sensors that are also connected through a master.
There are many advantages to using an IO-Link system, including standardized wiring, remote configuration, simple device replacement, advanced diagnostics, and increased data availability. Because IO-Link systems are open standard, the devices can be integrated in almost any fieldbus or automation system.
IO-Link sensors do not require any special or complicated wiring. Rather, IO-Link sensors can be connected using cost-effective standard three-core cables. In addition, IO-Link also eliminates the need for analog sensors and reduces the variety of interfaces for sensors, which saves inventory costs.
