IO Link

INNOVATIVE, CONNECTED, PREDICTIVE

IO-Link - a globally standardized IO technology (IEC 61131-9) for the integration of sensors in digital communication systems with reduced engineering effort and minimal hardware requirements. The high-performance point-to-point communication is based on the long-established 3-wire sensor connection and enables simple and cost-effective cabling of devices in the field. IO-Link is therefore not a fieldbus, but a further development of the proven connection technology for sensors.

The availability of data for predictive maintenance, as well as the quick and easy device replacement are further advantages of the IO-Link sensors, which are particularly suitable for cost-efficient applications with a high degree of automation.

What advantages do IO-Link sensors offer?

  • Direct and digital communication between sensors and IO-Link master
  • Automatic device recognition through coding
  • Interfaces and unshielded cables are standardized
  • Modular machine concepts can be perfectly supported
  • Automated, simple, tool-supported parameterization through function blocks
  • Extended diagnostic function down to the field device
  • Cable break detection
  • Device-dependent diagnosis via IO-Link
