4.4.1 Operation with IO-Link master
The unit is compatible with IO-Link master port class A (type A)�
For operation with IO-Link master port class B (type B) observe the following:
As a standard, the unit is not compatible with master port class B (type B)�
Pin 2 (OU2) and pin 5 (IN1) are used for manufacturer-specific functions�
That means that the main supply voltage of the unit and the additional volt-
age supply (master port class B on pins 2/5) are not electrically isolated�
With the following configurations the unit can be used with master port class B:
• Connect unit and IO-Link master via 3 wires: Connect pins 1, 3 and 4 of the
unit with the IO-Link master (do not connect pins 2 and 5)�
• Connect unit and IO-Link master via 4 wires: Deactivate pin 2 (OU2) via IO-
Link (setting OU2 = "off") and connect pins 1, 2, 3 and 4 of the unit with the
IO-Link master (do not connect pin 5)�
4.4.2 Extended functions
By means of IO-Link extended measured data are available�
The object reflectivity is provided via the display and as process data value (PDV)
via IO-Link�
The object reflectivity can, for example, be used to detect sensor soiling�
