This document discusses IO Link, a communication standard for connecting sensors and actuators in smart factories. IO Link allows bidirectional communication of device parameters and status information. It supports predictive maintenance by enabling real-time monitoring of devices. IO Link masters can automatically configure devices during changeovers to reduce commissioning time. Device diagnostics are accessible for quick troubleshooting to reduce downtime. OMRON provides IO Link hardware including masters and sensors that support these smart factory functions.

3. Smart Factories & IO Link
How IO link supports the smart factory concept
 Real time data collection from the
lowest level
 Communicate and escalate this data
for instant analysis in controller / IT
 Automatically and instantaneously re-
configurable
 Supports flexible and customised
production
 Automatic fault alerts
 Monitor down to product level for
predictive / preventative maintenance

4. IO Link Introduction
What is IO Link?
 Communication technology for
sensors and actuators
 Point-to-point communication
 3-Wire connection
 Open vendor protocol
 IEC 61131-9 (international standard)
Full communication

5. IO Link Introduction
What does IO Link do?
 IO Link allows status information to
be read from the device
 Information beyond on/off status
 Configuration parameters can be
transferred to the sensor

7. IO Link User Benefits
Key Business Drivers
 Reduce machine downtime
 Enable predictive / preventative
maintenance to reduce machine faults
 Reduction in changeover time
 Enhanced machine commissioning
efficiency

8. IO Link User Benefits
Easy Machine Troubleshooting >> Reduce machine downtime
 Failed / error sensor detection
 Wire break or short circuit detection
 Instantly identify the location of the
error
 Instantly identify the product which
has an error
 Fast device changeover through
automatic parameter download

9. IO Link User Benefits
Light Level Monitoring >> Predictive / Preventative Maintenance
 Dirt on a sensor causing unstable
measurements can be detected for
preventative maintenance.
 Misaligned sensor can be detected
before operation failure
 Operational time can be monitored
for predictive maintenance

10. IO Link User Benefits
Proximity Warning >> Predictive / Preventative Maintenance
 Detect excessive proximity to the
sensor via a dedicated status bit
 Monitor when target is outside of
stable detection area
 Identify mechanical issues before
they cause a machine fault

11. IO Link User Benefits
Automatic Configuration>> Reduction in Machine Changeover Time
 Configuration data can be sent to sensors
automatically for machine changeover
 Eliminating the need for manual intervention
 Reducing the possibility of manual setting
errors
 Reducing the time & complexity of machine
changeovers

12. IO Link User Benefits
I/O Check >> More Efficient Machine Commissioning
 Automatic network IO check provides instant
detection of incorrect sensor type or wiring
errors
 Guided information supports fast resolution
to errors

13. IO Link User Benefits
Batch Configuration >> More Efficient Machine Commissioning
 For serial machines all devices can be
automatically configured from master
program file
 Eliminating the need to configure
individual devices on each machine
build
 Reducing commissioning time of
machinery
