How Does Io-Link Work - Allen-Bradley RightSight 42EF Series User Manual

How Does IO-Link Work?

Real-time Diagnostics and Trending
• Real-time monitoring of the entire machine down to the sensor level
• Optimized preventative maintenance—identify and correct issues before
failures can occur
• Detect sensor malfunctions/failure
Sensor Health Status
• Real-time monitoring helps ensure that sensors are operating correctly
• Detect damaged sensors and pinpoint their exact location for quick
troubleshooting through Application Specific Name parameter
Device Profiles and Automatic Device Configuration
• "Golden" device configurations are stored in the IO-Link master module
• Multiple configurations can be stored in controller to support changes in
machine production, for example tool changes
• Within minutes instead of hours, modify sensor parameters to produce
different finished goods
Descriptive tags
• Faster programming during initial setup
• More efficient troubleshooting process-data tags are named based on the
information they provide
• Easily monitor sensor data though intuitive tag names
IO-Link delivers data over the same standard field cabling used today. By
connecting an IO-Link sensor to an IO-Link master, the field-device data and
diagnostics are accessible. So go beyond detecting products on the machine—
now the health of the machine can be MONITORED as it runs.
