IO-Link

IO-Link is a point-to-point communication protocol that is used to connect industrial automation devices, such as sensors and actuators, to controllers and other devices in a control system. It provides a standardized communication interface between these devices, allowing for easy configuration, monitoring, and control of devices from a central location.
One of the key features of IO-Link is that it is a digital communication protocol, which means that it provides much more information about connected devices than traditional analog systems. This information includes the device's identity, status, and diagnostic information, which can be used for predictive maintenance, fault detection, and other applications.

IO-Link operates over a standard three-wire connection, with one wire for communication and two wires for power. It can operate at speeds of up to 38.4 kbps over distances of up to 20 meters, depending on the specific implementation. IO-Link devices are typically connected to an IO-Link master, which acts as a gateway between the devices and the control system.

IO-Link has become increasingly popular in industrial automation applications due to its ease of use, flexibility, and cost-effectiveness. It is compatible with a wide range of devices and can be easily integrated into existing systems, making it an attractive option for many manufacturers and system integrators.
