The IO-Link success story continues
01 August 2016
After a surprisingly high number of installed IO-Link nodes was reported in the market survey of the technologies of PI (PROFIBUS & PROFINET International) in 2014, its rate of increase in the 2015 survey has again been impressive.
With over 3.5 million nodes in the field, an increase of 63% compared to the prior year was achieved.
Companies appreciate the easy installation and parameter assignment of IO-Link as well as its fieldbus neutrality. The fieldbus-independent IO-Link standard allows products to be connected to different systems and controllers and it has been implemented in almost all fieldbus systems established in the market. This also applies to most PLC manufacturers.
The success of IO-Link is also demonstrated by the growth in the number of members within PI's IO-Link community. In 2015 alone, 29 companies joined the IO-Link community. This trend continues in the current year with over 10 companies electing to collaborate with IO-Link and to bring products into the market, increasing the total number of companies active in the IO-Link community to 124, as of April 2016.
With IO-Link both cyclic and acyclic data exchange with the higher levels is possible. For example, it is possible to load configuration data in the sensor or actuator or vice versa, to deliver diagnostic or statistical data. Because it is integrated in all major automation systems, the connection to the ERP level is possible. As a result, IO-Link is the only technology for the kind of intelligent connection of sensors and actuators that is essential for a digital factory. In other words, with IO-Link the user is ideally prepared for the requirements of Industry 4.0
