system in order to save a valid parameter set�
Memory plug full
A valid parameter set is available in the memory of the
memory plug�
Memory plug
transparent

saving of the parameters all unfiltered sensor signals are
transmitted to the higher-level system�
For further data operation the operating voltage or the
connection sensor - memory plug must be interrupted
once�
[Write protected]

one parameter set can be written to the memory plug
once�
• If the memory plug is full (a parameter set is saved), it is
protected against further writing�
[Read/Write]
The memory plug is not protected against overwriting� The

type
Sensors of the same type have the same IO-Link device ID
or can take this ID in the compatibility mode� However, they
do have a different serial number�
Identical sensor
Physically identical device: The serial number of the sensor
and the saved parameter set are the same�
