Exchange data consistently with IO-Link – from the controller to the lowest field level.
Benefit from all the options offered by IO-Link: the point-to-point connection enables you to exchange both process data and service data between the connection and sensor/actuator.
IO-Link is the first I/O interface standardized worldwide. The technology is relatively new, but the number of products with IO-Link interface used is growing rapidly. The communication standard offers you many advantages, creates new application opportunities and constitutes an investment in important matters such as the Industrial Internet of Things (IIoT). By definition, IO-Link is an open-source, serial point-to-point communication protocol for connecting sensors and actuators to an automation system.
The architecture of an IO-Link system consists of a controller, one IO-Link master and one or more IO-Link devices. They are connected by simple 3-wire, unshielded cables, which makes installation easier and more cost-effective.
Productivity
IO-Link devices provide the controller with detailed status data. This data helps in maintenance planning because you can detect problems quickly. If you as a user receive a warning message from dirty sensors every six months, for example, you can plan cleaning them twice a year at convenient times. Furthermore, real-time fault detection of devices enables you to reduce operating costs by minimizing unplanned downtimes.
Simplicity
Everything in IO-Link is easy. Installation is easy because you can use standard cables and male connectors. Maintenance is easy because you can monitor your systems and make adjustments to your settings. Using error detections of the IO-Link devices, you can determine the cause of a problem easily and quickly. The replacement process is also easy thanks to the parameter data stored in the controller. If an IO-Link device must be replaced, the stored parameters are automatically copied to the IO-Link device without using a programming device. Thanks to this, your system will be operable again soon.
Increased data availability and accuracy
Analog sensors without IO-Link often pass through multiple A/D conversions before data reaches the controller, which may result in errors. In IO-Link devices, there is only one A/D conversion. This increases measuring accuracy and thus the accuracy of the entire process.
Remote configuration
You can modify the parameters of the IO-Link device from your desk by responding to status messages. In order to remedy faults, you therefore no longer have to shut down the production line and physically access the devices.
IO-Link devices supply three types of data:
