5.14 Humidity
5.14.1 Description
The function monitors the air humidity and informs of
changes through corresponding IO-Link events.
The humidity detection returns an immediate reaction in
the event of a critical failure. This reaction is triggered if the
humidity rises above a fixed threshold value and gives the
clear if a satisfactory humidity value is again achieved. The
status when the level is exceeded the first time is stored
permanently.
5.14.2 Process Data
Object ID Name Description Direction
0x0023 (35) Humidity Bad Output of the current humidity evaluation; FALSE means a
humidity below above the threshold value, TRUE means a
humidity value equal to or above the threshold value.

Humidity Bad
The status of the humidity is displayed as a Boolean value.
If the value is TRUE, the signal quality is above the
threshold value; if the value is FALSE, the signal quality is
below the threshold value. The evaluation includes a
hysteresis for better signal stability.
Operating Hours at Exceedance
The operating hours value at the first exceedance of the
threshold value is stored.
Temperature at Exceedance
The temperature value at the first exceedance of the
threshold value is stored.
