  netPI RTE 3: access from several comm. masters
Posted by: tad - June-2nd-2021, 05:07 AM - Forum: Software - Replies (3)

Dear Armin,

Can 'netPI RTE 3' perform real-time communication with multiple masters (PLCs)?
That means whether netPI can support Shared device function in case of PROFINET.

At this time, I have 2 EtherNet/IP scanners to communicate with 1 netPI.
Thank you very much for your advice.
Best regards,

  USB Device not plugged in during boot
Posted by: rlahnsteiner - May-30th-2021, 01:02 PM - Forum: Hardware - Replies (3)

I am using the hilschernetpi/netpi-nodered:latest.

In advanced container settings I have at Runtime&Resources
Privileg Mode
host /dev/ttyACM0 and container /dev/ttyACM0
I use this for a barcode scanner.

It works fine, but when I don't connect the scanner during boot then  the container wouldn't start. When I try to start the container it comes up with:

Failure linux runtime spec devices: error gathering device information while adding custom device "/dev/ttyACM0": no such file or directory

When I connect the scanner later then I can start it.
How can I get the container to start even when the barcode scanner is not connected?

  Rolling Back Firmware
Posted by: SSShahsavarani@Hilscher.com - May-26th-2021, 02:16 PM - Forum: Software - Replies (3)

I need to rollback a netPI from firmware version V1.2.2.0 to V1.2.0.0 is this possible? The only documentation I found in this regard is for the netCONNECT (screenshot below).

  IoT Edge Gateway: Node-RED - ARRAY -> OPC UA
Posted by: AxelHa2111 - May-21st-2021, 02:59 PM - Forum: Projects - Replies (5)

Hallo ALL,

I have a question about OPC UA.

I have a project with a OPC UA Server by Siemens Automation called Telecontrol Server Basic (TCSB). The Server is runing und working.

No I have to do a connection to IoT Edge Gateway by Hilscher with Node-Red.

The connection is also working and i can read some data from the Server. The data's on the Server are all Array by diffrent format's (sint, uint and udint).

Now i would like to write some values into a array (complettly or single array elements).

First i do it by a simple inject node with a function into a opc us output (is connected). But it didnt work.

The function code is "msg = {payload:{Value:{0:99,1:40,2:80,3:80,4:90,5:100,6:110,7:0,8:0,9:0}}};"

The error msg say "expecting a number". I don't now what number it mean's.

The opc topic is "dp.sp". The format is [array 0..0 of int]

Did anyone has an idea?

Thank you.

Question [NSHIELD 52-RE] Advise of basic steps
Posted by: Byrpierce.3nec - May-14th-2021, 08:20 AM - Forum: Software - Replies (1)

Hello everybody,
I would like to ask you if you would advise me the basic steps regarding the use of I-NUCLEO-NETX.


I have already prepared PROFINET communication scenario in SYCON.net and communication model in Simulink for Speedgoat target machine. Problem is, that i'm new to these shields for industrial network and basicly i don't know what to do. As a host I'm using board from STM, specifically STM32F429ZI-Nucleo. I have installed STM Cube IDE 1.6.1 with actual NETX-CUBE-Expanstion_1.3.0.1, where is already some DEMO project for PROFINET.

What I need is prepare own code and configuration for NSHIELD 52-RE and i would like to send 2x float (temperature, humidity) and receive 2 configuration bytes.

SYCON.net configuration:
Module Output 4 bytes
Module Output 4 bytes
Module Input 2 bytes

I think, that i need export this configuration and upload it on Shield.

Shield blinks red LED on COM1 - No data exchange.

Thank you very much for any help in this topic.

Best regards,

  Several questions
Posted by: rlahnsteiner - May-6th-2021, 11:48 AM - Forum: Hardware - Replies (3)

Hi, I just purchased my first NetPI RTE and have several questions:

1) Can I access the network settings in the Control panel from a node-red-app? 
2) How can I write/read data from a USB media from Node-red? (Tried to install usbmount, but didn't install.)
3) How can I change the display resolution? I get 640x480 only, unable to change it.
4) How can I set the Chromium-Browser to Kiosk-mode?

Thanks for your assistance.

Best regards


  netFIELD OS Kernel Version
Posted by: Irina Grinberg - May-2nd-2021, 02:16 PM - Forum: Software - Replies (7)

Hi Armin,
I see that the current version of Netfield OS is based on Linux Kernel version 4.19.71.
According to this thread - https://github.com/raspberrypi/linux/issues/3226
there is a UART issue fixed in Kernel version 4.19.97.

We encountered this issue using Raspbian OS on NetPi, and indeed updating the kernel solves it.
My question is - how often is Netfield OS updated with the latest kernel changes?

  Recovery for empty SD Card
Posted by: Dipro - April-27th-2021, 04:23 PM - Forum: Software - Replies (4)


I hab an issue with my SD card and it wasn't readably anymore. Now I can't use the recovery USB stick to restore my netpi. How can I create a new SD card with a base image, so that I can use my netpi again. Is there any base image I can use for that?
In other threads I read that the netpi OS is specific to each MAC adress of the netpi. Is there any other recovery method besides an USB stick with the recovery tools?


  netPI RTE 3 and Profibus
Posted by: Kanasak - April-23rd-2021, 09:38 AM - Forum: Hardware - Replies (2)

Hi everybody,

We have several netPI RTE 3 devices for a project and the customer is asking me if the netPI can communicate with PLC on Profibus protocol. I know the communication chip is a netX 51 SoC and I saw on Hilscher website a Profibus Slave firmware for netX 51 (product NXLFW-DPS, 7427.420). Is this firmware loadable into the netPI netX Soc ? And is there a linux driver available to use it with C ? Sample code would be also very appreciate Big Grin  !

Thanks all !


  Bluetooth testing
Posted by: DSongra - April-23rd-2021, 08:43 AM - Forum: Software - Replies (6)

Hello Armin,

I am testing netPI RTE for Bluetooth. Ipad act as another Bluetooth device to communicate & exchange data with netPi RTE.

I have installed the Node-red docker container from (https://hub.docker.com/r/hilschernetpi/netpi-nodered) & added Bluetooth related setting as below.


I can get a scan result in the Bluetooth node (attachment result). but after deploy & then inject it got to connect for 1 second then disconnected & then it gives an error (attachment error). complete debug error message (debug error message).
