Getting started with the P-NUCLEO-IOM01M1 full IO-Link master (PHY plus
stack) evaluation board and development system
Introduction
The P-NUCLEO-IOM01M1 is an STM32 Nucleo pack composed of the STEV
The STEVAL-IOM001V1 is a single IO-Link master PHY layer (L6360) while the NUCLEO- F446RE runs an IO-Link stack v.1.1
(developed by and property of TEConcept GmbH, license limited to 10k minutes, renewable without additional costs). IO-Link
stack update is allowed exclusively by following the procedure described in Section 5 Firmware update. Any other erase/
overwrite of the pre-loaded stack makes impossible to restore it.
The STM32 Nucleo pack provides an affordable and easy-to-use solution for the evaluation of IO-Link applications, L6360
communication features and robustness, together with the STM32F446RET6 computation performance. The pack, hosting up to
four STEVAL-IOM001V1 to build a quad port IO-Link master, can access the IO-Link physical layer and communicate with IOLink Devices.
You can evaluate the tool via the dedicated GUI (IO-Link Control Tool©, property of TEConcept GmbH) or use it as an IO-Link
master bridge accessible from the dedicated SPI interface: source code of demo project (Low-Level IO-Link Master Access
Demo Application, developed by TEConcept GmbH) and API specification are available for free.

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.
A single port master, as the P-NUCLEO-IOM01M1, can be schematized as the arrangement of two main blocks
(see Figure 2. P-NUCLEO-IOM01M1 block details):
• Control sub-system: the NUCLEO-F446RE board runs the IO-Link stack and firmware accepting user
commands, configuration parameters and controlling the remote IO-Link device. The NUCLEO-F446RE
board provides all digital signals to perform the proper control for single and multi-port (up to 4) IO-Link
master. You can evaluate the tool via the dedicated GUI (IO-Link Control Tool by TeConcept®) or use it as an
IO-Link master bridge accessible from the dedicated SPI interface.
• IO-Link physical: the STEVAL-IOM001V1 mounts the ST transceiver L6360, which interfaces with the
micro-controller by digital interfaces (I²C for status and configuration; UART for IO-Link data transfer) and
the IO-Link device by the IO-Link interface (type A or type B as defined by the standard).
, 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-IOM01M1 (STEVAL-IOM001V1 plus NUCLEO-F446RE)
•
• a power supply (18-32.5 V)
• a USB cable (type A to mini-B)
• an IO-Link (v1.1) device (e.g. P-NUCLEO-IOD01A1)
• connection cable/wires between IO-Link master and IO-Link device
• a Laptop/PC
The P-NUCLEO-IOM01M1 is a complete single port IO-Link master composed by two application boards
(STEVAL-IOM001V1 and NUCLEO-F446RE) connected via the CN7 and CN10 ST morpho connectors.
A power supply (from 18 to 32.5 V) is necessary to supply the STEVAL-IOM001V1 via the CN1 connector,
whereas the NUCLEO-F446RE can be supplied by connecting its mini-USB port to your PC/Laptop USB port
through a USB type A to mini-B USB cable.
For a full evaluation of the system, an IO-Link device compatible with specification v1.1 (for example, P-NUCLEO-
IOD01A1) is also necessary.
The IO-Link master can be controlled by the IO-Link Control Tool (through USB) of TEConcept, or by the SPI
interface available on CN7: in this case, a SPI master (for example, another STM32 Nucleo board programmed
with Low-Level IO-Link Master Access Demo Application) and the connection wires for SPI signals are necessary
(see also Section 3.3 Development system setup).

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:
• IO-Link Control Tool©(property of TEConcept GmbH)
• the IODD file of your IO-Link device
For application development:
• the SPI master control software (Low-Level IO-Link Master Access Demo Application)
2.2.1 Low-Level IO-Link Master Access Demo
The Low-Level IO-Link Master Access Demo application is an example of how to build host application for
controlling the IO-Link. It provides low-level functions which make possible basic communication with IO-Link
master (for example, to change the IO-Link port configuration, to read or write parameters, etc.).
The Low-Level IO-Link Master Access module has its own abstraction layers that run on dif
as Windows, Linux, Cortex-M) and provides different peripherals for the connection with the IO-Link master (such
as SPI, USB Virtual COM port, UART232, etc.).
For details on the control of the IO-Link master from your host application running on an embedded environment,
refer to Figure 9. P-NUCLEO-IOM01M1 development system connections.

How to build and run the IO-Link master
Step 1. Connect the STEV
morpho connectors.
Important:
The STEVAL-IOM001V1 evaluation board must be on the opposite side with respect to the NUCLEO-F446RE board mini-USB
connector
, as shown in the figure below.

Single port system evaluation setup
Step 7. Activate the power supply connected to the STEV
AL-IOM001V1.
Step 8. Reset the STEVAL-IOM001V1 by clicking the [reset] button.
Step 9. Reset the NUCLEO-F446RE by clicking the [black] button.
The system is now ready to operate and can be controlled by the IO-Link Control Tool.
Step 10. Click on [Inactive] to stop previous data exchange (refer to Figure 5. IO-Link Control Tool interface).
Step 11. Select [Port 1] tab and click on [Power OFF]: this action drives low the ENL+ signal and L+ line. CN3
does not supply the IO-Link device anymore (refer to Figure 5. IO-Link Control Tool interface).
Step 12. Click on [Select Device]: the Device selector window appears.
Figure 6. IO-Link Control Tool - IODD selection
Step 13. Select the IODD XML file of your IO-Link device from the list and click [Select Device].
The Device selector is then closed.
If the IODD files does not appear in the list, click [Import], browse your folders and then click
[Open] to
add the XML file of your IO-Link Device to the list of the Device Selector window.
Step 14. Click on [Power On] (ENL+ is turned ON and the IO-Link device is supplied by L+ line).
Step 15. Click on [IO-Link] to activate the wake-up request and establish communication with the IO-Link
device. The Device Status window shows the connection status (see Figure 7. IO-Link Control Tool -
sensor and data format activators)
Step 16. In the Parameter tab, open the Identification menu and double click on the right side of the Sensor
Activator “var”: a selection window opens to select the sensor to be activated.
If the P-NUCLEO-IOD01A1 is connected, select [All sensors are enabled (30)] and click anywhere
outside the window.
Step 17. Click on the [Sensor Activator] row and then click on the [Write Selected] button to definitively
activate the selection.
Step 18. In the Parameter tab, double click on the right side of the Process Data Layout “var”:
a selection window is open.
Step 19. Select the desired data to display (e.g. “Temperature + Humidity (7)”, if P-NUCLEO-IOD01A1 is used)
and then click anywhere outside the window.
