1.3 System requirements
To use the STM32 Nucleo development boards with the X-NUCLEO-IOD02A1 expansion board, you need:
• a Windows PC/laptop (Windows 7 or above)
• a type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
L053R8 or NUCLEO-L073RZ development board
• a type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-
G071RB development board
• the X-CUBE-IOD02 firmware and software package installed on your PC/laptop
• an IO-Link Master (e.g. P-NUCLEO-IOM01M1 ) with the related control tool (e.g. IO-Link Control Tool when
using the P-NUCLEO-IOM01M1 )
1.4 Board setup
Step 1. Check the configuration of JP5 (on NUCLEO-L053R8 or NUCLEO-L073RZ ) and set it to “U5V”, or
check the configuration of JP2 (on NUCLEO-G071RB ) and close between pins 1-2.
Step 2. Connect the mini-USB (for NUCLEO-L053R8 or NUCLEO-L073RZ ) or micro-USB (for NUCLEO-
G071RB ) to your PC and the STM32 Nucleo development board.
Step 3. Download the selected firmware onto the microcontroller.
You can use the tools available in your IDE,
STM32 LINK Utility or STM32CubeProgrammer and you
can select among different firmware packages (.bin or .hex) according to the MCU (STM32L0x or
STM32G0x), the communication speed (COM2 or COM3) and communication mode (Single-Byte,
Multi-Byte and Transparent). In Single-Byte and Multi-Byte communication modes, JP4 and JP5 remain
open. In Transparent communication mode, JP4 and JP5 must be closed.
Step 4. Disconnect the USB cable from the STM32 Nucleo development board and close JP5 to “E5V” (on
NUCLEO-L053R8 or NUCLEO-L073RZ ), or set JP2 from 1-2 to 3-4 (on NUCLEO-G071RB ).
In this setup, the STM32 Nucleo development board is supplied by the X-NUCLEO-IOD02A1 and the
step-down converter is active (for SW4 close pins 1-2) to supply Vin (JP8 closed). VDIG must be
referred to 3.3 V rail supplied by the
STM32 Nucleo development board (SW1 open, for SW2 close
pins 1-2).
Step 5. Connect the X-NUCLEO-IOD02A1 to the STM32 Nucleo development board through the Arduino
connectors.
Step 6. Connect the X-NUCLEO-IOD02A1 power section (CN1, CN2) to the IO-Link master according to the
schematic and serigraphy (see Section 1.1.2 Power section ).
Step 7. Open the control tool of your IO-Link master and upload the IODD XML file (included in the X-CUBE-
IOD02 software package).
You can select between the two IODD files according to the communication speed (COM2 or COM3) of
the firmware downloaded on the
STM32 Nucleo development board.
Step 8. Activate your IO-Link Master (usually requires a connection to a 24 V supply rail).
The IO-Link master control tool lets you supply the
X-NUCLEO-IOD02A1 L+ line and launch a wake-up
request to initiate communication.
Step 9. Set to the IO-Link port of the Master as digital input and then press the STM32 Nucleo development
board blue button to drive the CQ line status to 24 V/0 V.
