IO-Link is based on a point-to-point connection between the sensor/actuator and an interface module. Previously, 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.
Benefits: IO-Link users benefit from reduced machine costs, efficient processes and improved machine availability. Turck provides one of the most comprehensive IO-Link portfolios worldwide, from a variety of sensors, cables and active IO-Link junction boxes to interfaces for various industrial fieldbus protocols, including Turck Multiprotocol Ethernet products.
Standard Wiring: IO-Link does not require any special wiring. The sensors and actuators can continue to be connected using the proven, unshielded and attractively priced industrial three core cables. The operating modes available for selection are the standard switch mode and the communication mode.
Reduced 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 possible.
- Displays and switches no longer required on devices.
- Reduced engineering and assembly costs and automatic documentation of device parameters during the engineering phase.
Efficient Processes
- Extensive 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.
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 implemented.
- Device replacement without manual intervention to parameterize the new unit alleviates the need for qualified personnel.
