Exploring the 42EF IO-Link Parameters
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 the sensor was power cycled.
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 power cycled.
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:
In this section of the Diagnosis Tab, the user
can see 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) while in IO-Link mode. The user can also visualize the IO-Link
Revision of the sensor in this section.

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, take note that the Refresh function:
•
Is only enabled in online mode.
•
Is performed initially when the Add-on Profile is launched in online mode.
The alignment mode can be enabled for an indefinite amount of time or enabled
for limited intervals of 120 and 240 seconds.
