Internal Temperature
6.9.1
Description
The device has internal temperature monitoring. This
records the device temperature as well as the maximum
and minimum values since production and since the last
time the device was restarted.
An upper and a lower threshold value can be defined for
the device temperature module. If the threshold is
exceeded or if device limit values are exceeded or
undercut, the device triggers IO-Link events.
The internal device temperature is measured in the
device and is therefore higher than the ambient
temperature. The level of this increased
temperature depends on the ambient temperature,
the ventilation of the device and the device
settings.
