The IO-Link channels are designed as follows:
The IO-Link channels at pin 4 at connectors C6 and C7 can be parameterized independently and
can optionally be operated in IO-Link mode (IOL) or in standard I/O mode (SIO/DI mode).
The universal channels at pin 2 of connectors C6 and C7 are designed as DXP channels and can
thus be used as in- or output.
3.3 Power supply of the IO-Link ports
3.3.1 Class A/B supply
Class A supply: pin 1 and pin 3,
Class B supply: pin 2 and pin 5
o see
also Wiring diagrams (page 12)
NOTE
The two supply voltages are not galvanically isolated.
NOTE
Set the respective output (DXP 13 or DXP 15) in the process output data in order to acti-
vate the Class B supply, see Process output data – IO-Link master channels (page 16).
3.3.2 Safe shutdown of IOL2 (at C7)
The IO-Link port at C7 is supplied via the internal safe output FSO 1.
This allows a safety-related shutdown of the port.

NOTE
The IO-Link port at C7 is supplied via the internal safe output FSO 1.
Connected IO-Link devices must have a respectively high capacitance in order to tolerate
the test pulses of the safety output.
