Set up the serial terminal.
On your PC, open a serial terminal and configure it with the following settings:
- Baud Rate: 115200
- Data: 8-bit
- Parity: None
- Stop Bits: 1
- Flow Control: None
To set up the serial terminal on a Windows PC with PuTTY:
- Open Windows Device Manager to identify the correct COM port.
- Connect and disconnect the serial-to-USB dongle, and note which COMxx port appears and disappears (for example, COM10 is used in this guide; please use the COM port that matches your setup).
- Open PuTTY and go to Category > Connection > Serial.
- Configure the serial connection parameters as shown in the accompanying image, making sure to select the COM port that corresponds to your local setup.
- Go to Terminal and enable the Implicit CR in every LF option.
- Go to Category > Session and choose Serial for Connection type, then press Open.
Running the Pre-Built Demo Application
Download the ZIP release package file from SW44H19A and extract its content.
Format the SD card to FAT32 by adhering to the guidelines provided in the dedicated "How to Format and Partition an SD Card Larger Than 32GB Using DiskPart in Windows® for MPU" page.
Program the binaries to the SD card.
Copy boot.bin from the board-specific folder located at SW44H19A/bin/<devicename>/deps to the SD card.
Copy harmony.bin from the board-specific folder located at SW44H19A/bin/<devicename> to the SD card.
Insert the SD card into the board.
Press the RESET button on the board to initiate a reset.
The sample application will display a startup message on the serial terminal, as illustrated in the accompanying image.
Using a Diagnostic Tool to View the PROFINET Device
Download PRONETA BASIC 3.8 (or higher) from Siemens by logging in with a free account. Locate the ZIP file in the downloads section, download it, and extract its contents.
Run PRONETA.exe. If prompted to install the Npcap driver, click Yes to proceed.
Once the PRONETA window opens, navigate to the Settings menu.
In the Network Adapter pane, select the network adapter that is connected to the PROFINET device.
Navigate to the Network Analysis menu and select the Online tab.
The PC running PRONETA and the device running the PROFINET demo application will be displayed.
Right-click on the device and select Start Flashing LED.
The LED on the development kit will blink three times at a frequency of 1 Hz and will continue blinking with a short pause between cycles until you right-click on the device and select Stop Flashing LED.
Establishing a PROFINET IO Connection
As shown in the CODESYS documentation, configure a static IP address for the Windows PC Ethernet interface connected to the PROFINET device.
Go to Windows Settings > Network & internet.
Select the appropriate Ethernet interface, change the IP configuration to Manual, and configure the IP address and subnet mask accordingly.
Download CODESYS Development System V3 and install it on the Windows machine.
In the Windows taskbar system tray, right-click the CODESYS Control Win SysTray icon and select Start PLC.
Click OK if the following window appears.
Launch CODESYS from the Start menu.
Navigate to Tools > CODESYS Installer, and install the CODESYS Control Win add-on.
Navigate to Tools > Device Repository.
Click Install and select the GSD file located in SW70F56A/src/p-net/share to load it.
The GSD file is now successfully installed.
Navigate to File > Open Project and select SW70F56A/codesys/pn_demo_controller_win.project to load the project.
Double-click on Device (CODESYS Control Win…).
In the Communication Settings section, click Scan network and select your PC from the list.
This will display the following result:
Double-click on Ethernet.
In the General tab, click Browse and select the network adapter connected to the PROFINET device.
When performing this step for the first time, you may be prompted to create a username and password.
Click Yes and record the username and password for future reference.
If you are asked to log in, enter the username and password you just created:
Configure the IP address and subnet mask to match the values originally defined in the Windows Network & Internet settings.
Double-click on PN_Controller.
In the General tab, click Adjust to set proper values for Default Slave IP Parameter.
This configuration should result in the following:
Double-click on P_Net_multi_module_sample_app.
In the General tab, set an IP address for the PROFINET device. In this guide, we use 192.168.0.50.
Go to the Online menu and select Login.
If prompted by a confirmation window, click Yes.
Go to the Debug menu and select Start.
The PROFINET controller on the Windows PC will be in RUN mode, as indicated in the status bar at the bottom of the CODESYS window.
Double-click on P_Net_multi_module_sample_app.
In the General tab, the Status will be OK if a PROFINET connection is established to the PROFINET device.
Double-click on PLC_PRG to look at the project code.
The User LED should toggle continuously based on the state of the flashing bit controlled by the USER pushbutton.
Press the USER pushbutton to stop or restart the LED toggling.
You can check under PRONETA that the right IP Address is now assigned to your PROFINET device:

Next Steps
The PPOFINET device demo application can be connected to a Programmable Logic Controller (PLC) to establish PROFINET communication.
For detailed instructions, please refer to the PPOFINET user manual located in the SW44H19A/ folder.
The user manual provides guidance on setting up a CODESYS® soft PLC on a Raspberry Pi or a Siemens PLC to communicate with the PROFINET device demo application, utilizing the board’s button and LED as input/output devices.
Troubleshooting
The serial terminal is not displaying any output. | If the terminal does not display any output, consider the following possible causes:
|
The terminal only displays RomBOOT message. |
|
The image on the SD card is not booting. |
