What is IO-Link?Most sensors and actuators today are already equipped with microprocessors, which can be used for parameterization, storing configuration data, and controlling indication. The obvious next step is to overcome the bottleneck of the binary standard interface and make additional functions centrally accessible for the automation system.
IO-Link is based on a point-to-point connection between the sensor/actuator and an interface module. Up to now, the binary connection was only designed for transferring switching information, but IO-Link now allows two bytes to be transferred normally in a 2 ms cycle via a combined switching status and data channel. Other information can be exchanged in addition to the process values, such as parameters or diagnostics messages. This enables communication with sensors and actuators down to the “last meter” to be established for universal communication.
- Exhaustive parameterization options for just-in-time parameter changes to devices
- Efficient processes requiring different parameter sets for switching thresholds, gain, sensitivity and so forth due to differing production conditions
- Faster tool change operations
IO-Link Reduces Machine Costs
- Reduced inventory due to intelligent multi-purpose devices
- Only one I/O module and one inexpensive standard cable required
- Reduced I/O footprint
- Displays and switches no longer required on devices
- Reduced engineering and assembly costs and automatic documentation of device parameters during the engineering phase
Improved Machine Availability
- Comprehensive status information and diagnostic capabilities in the plant lead to drastically reduced machine downtime
- Enhanced information enables cost saving mechanisms such as predictive maintenance or asset management to be easily
- Device replacement without manual intervention to parameterize the new unit alleviates the need for qualified personnel

Ultrasound reflection measurements offer an error-free and efficient solution for detecting the presence of objects on conveyor systems. The RU IP67 ultrasound sensor from Turck reliably detects objects.
Laempe Mössner Sinto GmbH uses IO-Link in a new core shooter machine and achieves shorter cycle times with Turck’s QR24-IOL IO-Link encoder.
At the differential gear product plant of a Chinese auto parts supplier, Turck is showing how its IO-Link solution for signal connection is easy, fast, and efficient.
The automation of a production line for exhaust systems enables Turck to demonstrate the flexibility of its BL20 multiprotocol gateway in conjunction with the IO-Link-capable TBIL hubs.
