Review the 1734-4IOL IO-Link AOP
Chapter 9
Temperature
In this section, the operator is able to monitor the actual, minimum, and
maximum internal temperature of the sensor.
• Actual – Since Power Up: Displays the current internal temperature of
the sensor.
• Maximum – Since Power Up: Displays the maximum sensor internal
temperature since the last time power cycle of the sensor.
• Maximum: Since Inception: Displays the maximum internal
temperature of the sensor since the first time the sensor was ever
powered ON. This value is retained and not lost during default factory
reset.
• Minimum: Since Power Up: Displays the minimum internal
temperature of the sensor since the last time the sensor was powered.
• Minimum: Since Inception: displays the maximum internal temperature
of the sensor since the first time the sensor was ever powered ON. This
value is retained and not lost during default factory reset.
Communication Characteristics
This section has read-only (ro) values for the Minimum Cycle Time (response
time of the sensor) and the Master Cycle Time (time that is used by the master
to address the sensor). You can also visualize the IO-Link revision of the sensor
in this section.
Manage Parameter
Differences between IO-Link
Devices and Controllers
The Add-on Profile has a Refresh button that updates the read-only
parameters for all channels with IO-Link devices. It also performs a
Correlation check of the read-write parameters in all connected IO-Link
devices and in the controller.
Differences in parameter values can happen when the device configuration is
changed externally, such as through a device console during operation. If there
are differences after running a Correlation check, you can choose to use the
parameters that are currently in the connected IO-Link device or to use the
parameters that are stored in the controller. The changes can be done on a per
channel basis.
Before you proceed with this task, the Refresh function is:
• Only enabled in online mode.
• Performed initially when the Add-on Profile is launched in online mode.
