7.5.10 Threshold value for signal quality

(only available for BML SL1-ALZ1-UEZZ-_U1L-...)
The threshold value can lie between 0...100%. If the
threshold value is set to 255% (0xFF), threshold value
monitoring is disabled.
If the signal quality is less than or equal to the threshold
value, the Status bit is set to 4 (see Tab. 7-3 on
page 25) and the Event Low Signal Quality Level (see

deactivate certain functions of the IO-Link device.
With the BML SL1 it is possible to lock out the function of
the parameter manager and the button. To do so, the
respective bit of the 2-byte value must be set to 1 (locked).
In order to unlock the parameter manager, bit is set to 0.
