Getting started with P-NUCLEO-IOD01A1 IO-Link (v1.1.3) multi-sensor node

Introduction

The P-NUCLEO-IOD01A1 is an STM32 Nucleo pack composed of the NUCLEO-L073RZ

IOD003V1 evaluation board and the X-NUCLEO-IKS01A2 expansion board.

The STEVAL-IOD003V1 offers an IO-Link device PHY layer (L6362A) while the NUCLEO-L073RZ runs the IO-Link stack v1.1.3
included in the STSW-IOD01 (developed by and property of TEConcept Gmbh) and the firmware controlling the X-NUCLEO-

IKS01A2 sensors.

The STM32 Nucleo pack provides an affordable and easy-to-use solution for the development of IO-Link and SIO applications,

L6362A communication features and robustness, together with the STM32L073RZT6 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 fieldbus.

An IO-Link device, as the P-NUCLEO-IOD01A1, can be basically schematized as the arrangement of three main
blocks (see Figure 2. P-NUCLEO-IOD01A1 block details):

• Control sub-system: the NUCLEO-L073RZ board runs the control software, the IO-Link 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 STEVAL-IOD003V1 mounts the ST transceiver L6362A, which interfaces with the
micro-controller by digital interfaces UART for IO-Link data transfer, GPIO and interrupts) and the IO-Link
master by the IO-Link interface (connector CN1).

• Sensor: the X-NUCLEO-IKS01A2 multi-sensor shield, with on-board temperature and humidity sensor
(HTS221), MEMS 3D accelerometer and 3D gyroscope (LSM6DSL), MEMS 3D accelerometer and
magnetometer (LSM303AGR), MEMS pressures sensor (LPS22HB).

, 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, the hardware requirements are:

a P-NUCLEO-IOD01A1 (STEVAL-IOD003V1 plus NUCLEO-L073RZ plus X-NUCLEO-IKS01A2)

•

• 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 P-NUCLEO-IOD01A1 is a complete IO-Link multi-sensor composed of three application boards (STEVAL-

IOD003V1, NUCLEO-L073RZ and X-NUCLEO-IKS01A2) connected via the Arduino connectors (CN5, CN6, CN8

and CN9).

A supply rail (up to 35 V) is necessary to supply the STEVAL-IOD003V1 via CN1 connector, while the NUCLEO-

L073RZ can be supplied in two different ways:

1. by enabling the LDO1 mounted on the STEVAL-IOD003V1 (open JP3; close JP4 and JP5) and setting JP5
on the STM32 Nucleo development board to position “E5V”;

2. by connecting the mini-USB port of the STM32 Nucleo development board to your laptop/PC through a USB
type A to mini-B USB cable. In this case, the STM32 Nucleo development board JP5 must be closed in the
position “U5V” and the STEVAL-IOD003V1 jumpers JP3, JP4 and JP5 must be open.

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-

IOM01M1 as IO-Link master, then the control tool is the IO-Link Control Tool©, property of TEConcept GmbH

• the P-NUCLEO-IOD01A1 IODD file (included in the STSW-IOD01 and available on www.st.com)

For application development:

• a software development environment (STM32CubeIDE 1.3.0, EWARM v8.32.3 or MDK-ARM v5.29.0)

• the STSW-IOD01 software package (including source code and IO-Link stack library, available on

www.st.com)

• the IODD file of your application

The P-NUCLEO-IOD01A1 is provided with the IO-Link stack included in the STSW-IOD01 software.

The software also includes an IO-Link library that developers can use to compile and link their sensor code.

The stack library contains a 30-minute runtime limited version of the TEConcept IO-Link stack.

The library is intended for evaluation purposes and its limitations are:

• data storage and block parametrization are not supported

• vendor ID, product ID, product name and device ID cannot be changed

• 30-minute execution time

After 30 minutes, a notification event that indicates “FW test phase expired” is shown and the IO-Link stack stops
working. A power-on reset is required to restore the operation.

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

UM2425 - Rev 3

UM2425

Software requirements

• 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.

The STSW-IOD01 software package includes an IODD file for P-NUCLEO-IOD01A1 complete evaluation.
