8 Rockwell Automation Publication IOLINK-UM001A-EN-P - August 2017
Chapter 1 836P Pressure Sensor with IO-Link Overview
Real-time Diagnostics and Trends
• Real-time monitoring of the entire machine down to the sensor level
• Optimized preventive maintenance—identify and correct issues before
failures can occur
• Detect sensor malfunctions/failure
Sensor Health Status
• Real-time monitoring verifies 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
How Does IO-Link Work?
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. IO-Link allows you to go beyond product detection
on the machine. You can now monitor the health of the machine as it runs.

IMPORTANT The response time of an IO-Link system may not be fast enough for high-
speed applications. In this case, it is possible to monitor or configure the
sensor through IO-Link on pin 4 of the sensors while connecting pin 2 (if the
sensor offers a second output) of the sensor to a standard input card.
