IO-Link Installed Base Reaches 71 Million as Adoption Expands
Growing adoption, richer diagnostics, and easier data integration are expanding IO-Link’s role in industrial automation.
As factories become more connected, sensors and actuators are expected to provide more than basic signals. Standardized communication, remote parameterization, and device diagnostics are becoming increasingly important at the field level.
According to the IO-Link Community, approximately 9.7 million new IO-Link devices and master ports were installed worldwide in 2025, bringing the global installed base to 71 million. The growth reflects continued demand for simpler integration and smarter device communication.
IO-Link enables bidirectional communication between field devices and control systems, providing access to process data, parameters, status information, and diagnostics. This can simplify commissioning, support maintenance, and improve data integration across automation systems.
Key Industry Takeaways
