IO-Link in process automation

IO-Link is an open communication protocol that establishes a bidirectional, digital connection between field devices (measuring instruments, switches and actuators) and industrial control systems (such as PLC applications). IO-Link operates with a point-to-point architecture in which an IO-Link master controls communication with multiple IO-Link devices. IO-Link transforms simple sensors into intelligent data points and provides real-time transparency and control without increasing complexity. Through standardized diagnostics and remote configuration functions, IO-Link helps keep simple measurement scenarios stable and predictable.
