Hardly any other technology has shaped industrial automation in recent years as much as IO-Link. What once began as a promising approach to improving communication between sensors, actuators and controllers is now an integral part of modern systems. But the question remains: Is IO-Link a trend – or has it long since become a fixed standard in the industry?
When IO-Link was developed in the early 2000s, the idea was revolutionary: intelligent, bidirectional point-to-point communication between field devices and controllers. The aim was not only to transmit switching signals, but also to make valuable diagnostic and process data available.
IO-Link was officially included in the international standard IEC 61131-9 back in 2006. This made it clear that IO-Link was not a short-lived trend, but an officially recognized communication standard.
Today, IO-Link is considered an integral part of the industrial infrastructure – and forms a crucial basis for topics such as Industrie 4.0 and IIoT (Industrial Internet of Things).
The success of IO-Link is based on three key features:
These features make IO-Link a reliable technology standard that applications and manufacturers worldwide can rely on.
Despite its standardization, IO-Link remains highly topical – because the technology is constantly evolving.
With IO-Link Wireless, for example, an important step has been taken towards wireless communication: even more flexible, more robust and ideal for moving machine components or areas that are difficult to access.
At the same time, topics such as data analysis, condition monitoring and predictive maintenance continue to drive the relevance of IO-Link. Sensors not only provide measured values, but also valuable information about the condition of systems – a decisive advantage for modern, networked production environments.
In this sense, IO-Link remains a trending topic: not because it is new, but because it is actively shaping the future of automation.
Numerous wenglor products are IO-Link-capable and enable easy integration into existing systems.
With IO-Link, we create the basis for transparent, networked and efficient manufacturing processes – and support our customers on the way to the smart factory.
IO-Link has long since made the leap from technological trend to globally recognized standard. But it is precisely this strength that ensures that it remains in vogue: because it is constantly evolving, opening up new possibilities and decisively advancing the digitalization of industry.
In short: IO-Link is the standard that sets the trend.
