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.

Device Temperature

Device 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).

Device Temperature Alarm Configuration

Setting of the lower threshold value (in °C) for the device temperature warning (0x8D20) and of the upper threshold value (in °C) for the device temperature warning (0x8D10).

Events

Internal temperature – Events
Event Code	Event Type	Event – Description – Remedy	Device Status
0x4000 (16384)	Error	Temperature Fault – Overload – The device is operated outside of the device-specific temperature limits. Risk of device damage.	4 – Failure
0x4210 (16912)	Warning	Device Temperature Overrun – Clear Heat Of Source – Risk of device damage. The device is too hot. Remove heat source, provide the device with heat insulation if necessary.	2 – Out-of-specification
0x4220 (16928)	Warning	Device Temperature Underrun – Insulate Device – Risk of device damage. The device is too cold. Insulate the device.	2 – Out-of-specification
0x8D10 (36112)	Warning	Device Temperature Upper Warning – The set upper temperature warning threshold has been exceeded.	0 – Device is operating properly.
0x8D20 (36128)	Warning	Device Temperature Lower Warning – The device temperature has fallen below the set lower temperature warning threshold.	0 – Device is operating properly.
