3 How to build and run the IO-Link device
3.1 System evaluation setup
P-NUCLEO-IOD02A1 can be used as IO-Link Device evaluation system, following the hardware configuration
below.
Step 1. Maintain the X-NUCLEO-IOD02A1 default configuration.
Close JP4 and JP5 if the Transparent Transmission Mode is selected.
Step 2. For the NUCLEO-L452RE setup, enable the external supply from X-NUCLEO-IOD02A1 by setting JP5
to position “E5V”.
Step 3. For the X-NUCLEO-IKS02A1 setup:
– enable all sensors by closing JP1, JP3, JP11 and JP12
– JP2 closed on INT1
– JP4 open
– JP5 closed on 1V8
– JP6 closed on 5-6
– JP7 closed 1-2 and 3-4
– JP8 closed 1-2 and 3-4
– JP9 closed on DRDY
– JP10 closed on INT
Step 4. Connect the X-NUCLEO-IOD02A1 evaluation board to the X-NUCLEO-IKS02A1 expansion board and
the NUCLEO-L452RE development board through the Arduino connectors.
Note: Connect the boards as shown in Figure 3 , leaving the two user buttons (the blue and the black ones) out.
Step 5. Connect the X-NUCLEO-IOD02A1 to the IO-Link Master by screwing cables on the CN1 connector,
taking care of the pin/signal correspondence.

Step 6. Install the P-NUCLEO-IOD02A1 IODD file (included in the FP-IND-IODSNS1 ) in the laptop/PC where
the control tool of your master is running. Depending on the control system of your master, it could be
required that you launch the control tool first and then load the IODD file.
The system is ready to operate: the IO-Link master control tool allows the user to supply, configure
and activate the data transfer (in SIO or IO-Link mode) with the IO-Link device. If the master is the
P-NUCLEO-IOM01M1 , refer to its user manual (UM2421 on www.st.com) for the detailed procedure to
use the related control tool.
3.2 System development setup
You can use the P-NUCLEO-IOD02A1 evaluation pack as a development platform for an IO-Link device sensor
node, but with a different firmware managing the sensors.
