6.4 Configuration of the LioN-P
PROFINET I/O modules in STEP 7
6 Starting operation
In this mode the channel operates as a digital input. The
IO-Link master does not try to establish communication
to a connected IO-Link device.
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.
In this mode the IO-Link device can be parametrized
during the module’s startup time and changes to digital
input mode via the fallback mechanism.
Additionally, the cyclical output bits in the COM control
byte (chapter 8.5.5) of the IO-Link master can be
used at any time to set the appropriate channels in
COM mode and thus enable the IO-Link device for
parametrization.
Attention:
Please note that the status of the digital input signal is not
updated during optional COM operations.
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 3x8-121 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 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
