6.4 Configuration of the LioN-P PRO-
FINET I/O modules in STEP 7
Technical manual LioN-P PROFINET IO-Link Master
Release 2.0 04/2017
 Digital Output:
In this mode, the channel operates as a digital output. It is impossible
at any time to communicate with the connected device.
The “Digital Output” option for IO-Link C/Q channel (ch. A/pin4) is not
available for the 0980 ESL 308-121 device.
 Inactive:
This mode should be selected if the channel is not used. The L+ power
supply (pin 1) of the port is disabled in this case.
 IO-Link in SIO mode (DI):
This mode is used to parameterize the IO-Link devices. It relies on the
fallback mechanism from COM mode to SIO mode, without using the
COM mode bits in the IO-Link master's status/control module. In this
mode, the IO-Link device is parameterized at module startup time, and
then changes back to digital input mode via the fallback mechanism.

IO-Link …:
In this mode (COM mode), the process data from or to the device are
exchanged over a communication link. The IO-Link master
automatically starts communicating with the connected IO-Link
device, taking into account the baud rate. Additionally, this mode offers
the option of parameterizing the IO-Link device.
Configuration modules with data lengths of 1-32 input and/or output
bytes are available.
If no suitable configuration module is available for the device, the next
larger data length must be selected.
