Introduction

The P-NUCLEO-IOD02A1 is an STM32 Nucleo pack composed of the X-NUCLEO-IOD02A1 and X-NUCLEO-IKS02A1 expansion boards stacked on the NUCLEO-L452RE development board.

X-NUCLEO-IOD02A1 features an IO-Link device transceiver for the physical connection to an IO-Link master, while the

The

X-NUCLEO-IKS02A1 features a multi-sensor board for industrial applications, and the NUCLEO-L452RE features the necessary

hardware resources to run the FP-IND-IODSNS1 function pack and to control the transceiver and multi-sensor boards.

The FP-IND-IODSNS1 combines an IO-Link demo stack library (derived from X-CUBE-IOD02) with the X-CUBE-MEMS1 and features an example of IO-Link device multi-sensor node.

The P-NUCLEO-IOD02A1 can be used for evaluation purpose and as development environment.

The STM32 Nucleo pack provides an affordable and easy-to-use solution for the development of IO-Link and SIO applications, evaluation of L6364Q communication features and robustness, together with the STM32L452RET6U computation performance.

1 Architecture overview

A generic IO-Link system is composed of an IO-Link Master and an IO-Link Device connected by an unshielded cable. Normally system.

The IO-Link Master is installed in the control cabinet or, as a remote I/O, directly in the field. It can have several IO-Link ports (channels): an IO-Link Device can be connected to each port, hence, it is a point-to-point communication and not a field-bus.

An IO-Link Device, as the P-NUCLEO-IOD02A1, can be basically schematized as the arrangement of three main blocks (see Figure 2):

• Control sub-system: the NUCLEO-L452RE board runs the FP-IND-IODSNS1 control software, the IO-Link demo stack and sensors firmware, accepting the commands and configuration parameters from the IO-Link master. It also provides all digital signals to perform the proper control of the whole IO-Link device system.

• IO-Link physical: the X-NUCLEO-IOD02A1 mounts the ST L6364Q transceiver, which interfaces the microcontroller and the IO-Link Master with the IO-Link interface (connectors CN1 and CN2).

• Sensor: the X-NUCLEO-IKS02A1 multi-sensor shield, with on-board MEMS 3D accelerometer + 3D gyroscope (ISM330DHCX), MEMS 3D magnetometer (IIS2MDC), MEMS 3D accelerometer low power (IIS2DLPC) and MEMS digital omnidirectional microphone (IMP34DT05).

, the IO-Link Master is the connection point between the IO-Link Device and the automation

2 Getting started

2.1 Hardware requirements

To evaluate the system, you need:

•

a P-NUCLEO-IOD02A1 (X-NUCLEO-IOD02A1 plus NUCLEO-L452RE plus X-NUCLEO-IKS02A1)

• an IO-Link Master (e.g. P-NUCLEO-IOM01M1) together with a power supply (18-32.5 V for the P-NUCLEO-

IOM01M1)

• a USB cable (type A to mini-B)

• connection cable/wires between IO-Link master and IO-Link device

• a laptop/PC

The three boards included in the P-NUCLEO-IOD02A1 are connected and communicate with each other through the Arduino connectors (CN5, CN6, CN8 and CN9).

The P-NUCLEO-IOD02A1 is supplied by the IO-Link Master via the X-NUCLEO-IOD02A1 CN1 and CN2 connectors (L+/24V and L-/GND pins).

The L6364Q embedded DC-DC generates a 10.4 V rail supplying the NUCLEO-L452RE through VIN net: you have to set NUCLEO-L452RE JP5 on E5V position to generate the 3.3 V rail to supply the rest of the system.

To flash the NUCLEO-L452RE, you have to disconnect the P-NUCLEO-IOD02A1 from the Master, set JP5 to U5V position and then connect it to your laptop/PC via USB cable (type A to mini-USB).

Getting started

2.2 Software requirements

To complete the system, you need a PC/laptop with:

•

Windows®(version 7 or above)

• STSW-LINK009 driver installed

For system evaluation only:

• the IO-Link master control tool provided with your IO-Link master hardware. If you are using the P-NUCLEO-

• the P-NUCLEO-IOD02A1 IODD file (included in the FP-IND-IODSNS1 and available on www.st.com)

For application development:

• a software development environment (STM32CubeIDE, EWARM, MDK-ARM)

• the FP-IND-IODSNS1 software package (including source code and IO-Link stack library, available on

www.st.com)

• the IODD file of your application

2.2.1 IODD file

The IODD file (IO device description) is the electronic device description file necessary for each IO-Link device.

The file stores a variety of information for the system integration:

•

communication properties

• device parameters with value range and default value

• identification, process and diagnostics data

• device data

• text description

• device illustration

• manufacturer logo

To ensure the same handling of all IO-Link devices, independently of the manufacturer, the IODD file structure is always the same for all manufacturer devices and it is always represented in the same way by the IO-Link configuration tools of the master manufacturers.
