ID keys 
The ID keys are used in the ID key-operated switches. Using the four ID keys with different 
codes, it is possible to select 1 of 4 positions. The ID keys are color-coded (yellow, blue, red, 
green, white) so that they can be clearly differentiated at a glance. The white ID key is 
supplied without coding and can be individually encoded via IO-Link using the electronic 
module for ID key-operated switches for IO-Link. 
Different versions of ID keys are available depending on the following features: 
●  Authorization level (different colors) 
For further information refer to Chapters "Operating principle of the command point with 
ID key-operated switch (Page 214)" and "ID key-operated switches (Page 78)". 
Authorization level  
The ID keys are divided into five authorization levels. The authorization levels 1, 2, 3 and 4 
as well as "Individually encodable ID key". Authorization levels 1 to 4 correspond to the 
maximum key position. The authorization level "Individually encodable ID key" has no 
maximum key position in the standard setting. The user can configure the key position in 
accordance with one of the authorization levels 1 to 4. This configuration option is only 
available with the white ID key.
