Internal Temperature
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.
Note
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.

Internal Temperature
Internal Temperature contains information about the device temperature (current value in °C), the minimum or maximum device temperature since the last time the device was switched on/reset (in °C) and minimum or maximum device temperature during the lifetime of the device (in °C).
Internal Temperature Alarm Configuration
Setting for the lower threshold value (in °C) for the device temperature warning (0x8D20) and upper threshold value (in °C) for the device temperature warning (0x8D10).
