Chapter 2 IO-Link Overview
Real-time Diagnostics and Trending
•
Real-time monitoring of the entire machine down to the IO-Link device
level
•
Optimized preventative maintenance-identify and correct issues before
Anomaly can occur
•
Detect IO-Link device malfunctions/Anomalies
IO-Link Device Status
•
Real-time monitoring verifies that IO-Link devices are operating
correctly
•
Detect damaged IO-Link device and pinpoint their exact location for
quick troubleshooting through Application-Specific Name parameter
Device Profiles and Automatic Device Configuration
•
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 device data though intuitive tag names
How IO-Link Works?
IO-Link delivers data over the same standard field cabling used today. By
connecting an IO-Link device 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.

IMPORTANT
It is possible that the response time of an IO-Link system is not fast
enough for high-speed applications.
