  Start Up Queries
Posted by: yongzhi - July-14th-2021, 11:25 AM - Forum: Software - Replies (3)

Dear all,

could you point me any starter guide?

It took me sometime to get NetPi run with one netpi-raspbain container run. But failed on the netpi-nodered. It is about time to clear some doubts.

Q1, Is it normal that netpi is only accessible from the remote PC in the same network? When I first power up, the conosle seems pending at "update UTMP abut system Runlevel Change". I used to thought the console will prompt the username and password, as a usual raspbian.

Q2. Netpi relies on DHCP of the router immediately above it, otherwise, remote access failed.

Q3. When we access docker, Portainer should appear as a running container, but I don't see it. Isn't it?

Q4. Do we have a command line approach to run a container? I have to configure the resources piece by piece from Portainer->Contianers->Add Container.

Hello Armin!

can I pull the hilschernetpi/lockforcontainer for testings?


Kind regards,


  Docker exposed port don't send data on eth0
Posted by: COswald - July-12th-2021, 11:06 AM - Forum: Software - Replies (3)

Hello Armin,

I have an issue, that is hard to descript. 

Base is a NIOT-E-TPI51-EN-RE.
Eth0 is configured as DHCP and working, I can connect to the Portainer and Control Panel from the outer netwerk to this IP-Address
On this box Docker is enabled
First Container is a hilschernetpi/netpi-netx-ethernet-lan image, which enables the cifx0 as 'normal' Ethernet-Port.

cifx0 is configured as
- IP-Address:
- Gateway:
- DNS:

In the Docker a second Container which if from image hilschernetpi/netpi-raspbian is running a node script to build a OPC UA server.
This Container exposes the following ports
remote 2222: local 22 --> SSH
remote 4334: local4334 --> opc.tcp

I can access the SSH port of the second container (2222) from eth0 and cifx0 without any problems
opc.tcp (4334) is available from cifx0, but if I try to connect from eth0 I cannot get a connection. A ping on that port is working, but i don't get data.

Firewall settings
eth0: NAT-Trusted
cifx0: Trusted (default)

- no routes defined -

I do not see the error, but I'm sure it is just in front of my eyes.

Can you give me a hint?

Kind regards,


  Remot VPN connection from netPI to company network
Posted by: JG_KIT - July-6th-2021, 02:01 PM - Forum: Software - Replies (6)


I am looking for a guideline on how to connect my netPI from a remote location (it will be connected to a standard household router with internet access) to my companies network via VPN. Meaning, I want the netPI to act as a VPN client and automatically connect to my specific company network on startup to then access the netPI from my company network like if it was directly connected. 
I assume, I need to install a package for that, but could not find it on my search so far. 
Thanks a lot in advance for your help.

Best regards,

Under the brand sensorEDGE Hilscher is releasing two IP67 rated Edge IO-Link master sensor blocks with added computing power 4th quarter 2021.

The boxes are available in two models named "sensorEDGE" and "sensorEDGE FIELD".

sensorEDGE is a "ready-to-use" instant over-the-cloud IO-Link sensor data provisioning solution while sensorEDGE FIELD is a "do-it-yourself" application open Edge IO-Link master computing platform.

  netPI core as serial device server
Posted by: MGharat - June-16th-2021, 07:45 AM - Forum: Hardware - Replies (1)

Hi Armin,

Hope you are doing well.

Do we have serial ascii / proprietary protocol support for netPI over RS232/RS485 NPIX board?

we earlier tested Modbus RTU protocol, which works OK with our NPIX serial boards, but about ascii we have not tested , anybody has experience ?

Currently we have here one customer requiremnet, who wants to collect weight measurement data ( Serial RS232/RS485 ) over Ethernet based server system for data integration ( TCP Server, TCP Client, UDP Server/Client, Pair Connection, SNMP  ). 
so the weight measurement data can be accessed from anywhere in server network.

Thanks in advance

  Ethernet trouble(Hardware failure?)
Posted by: m-yoshikawa - June-15th-2021, 07:27 AM - Forum: Hardware - Replies (13)

I have ethernet trouble with a certain netPI device(MAC addr: B827EB538466)
During a data transfer through ethernet connection, the connection may lost suddenly.

In syslog, I found a log message that "usb usb1-port1: disabled by hub (EMI?), re-enabling".
Since the recorded time of this log message is well corresponded with the time of connection lost, I suppose this is the root of this problem.
Based on the fact that the ethernet on the LAN9514, which is a microchip on raspberry pi, runs from usb, it is reasonable.

Since this problem does not occur with another netPI device(MAC addr: B827EBEFDC49), I suppose some hardware failure occurs this problem.
However, I am not sure.
So, Please tell me more if you know about this problem.

Best regards,

  Node-RED: OpcUa Client node
Posted by: tad - June-8th-2021, 04:05 AM - Forum: Software - Replies (4)

Dear Armin,

If I take out the 'OpcUa Client' node and set its properties as attached png files and deploy it, the following error will occur.
I tried it with netPI RTE 3 system software version both and
If I use UaExpert on a PC side, this software tool can communicate with Siemens S7-1500 properly.

OPC UA connection error: Command failed: "openssl" req -new -sha256  -text  -extensions v3_selfsigned  -config "/root/.config/node-opcua-default-nodejs/PKI/own/openssl.cnf.tmp" -key "/root/.config/node-opcua-default-nodejs/PKI/own/private/private_key.pem" -out "/root/.node-red/node_modules/node-opcua-client/certificates/client_selfsigned_cert_2048.pem.csr" -subj "/C=FR/L=Orleans/O=Sterfive/CN=NodeOPCUA-Client@NTB827EBB5D102"

Moreover, as NoderedContainer_1.png, I cannot map a volume when creating the Node-RED container.
I am afraid it is the reason for the error above.

Thank you very much for your advice.

  EtherNet/IP, 2 kinds of connections
Posted by: tad - June-4th-2021, 02:57 AM - Forum: Software - Replies (1)

Dear Sir/Madam,

I have never used netFIELD as an EtherNet/IP adapter, but I'd like to ask you the following configuration, please.

Is it possible to perform the following communication?
- netFIELD Connect, PLC1 and PLC2 are connected on the same network.
- Create a Node-RED container and perform I/O implicit communication between netFIELD Connect and PLC1.
- netFIELD Connect listens (wiretaps) to I/O implicit communication data from PLC1 to PLC2.

Because I want to exchange data between netFIELD and PLC1, and gather data from PLC1 to netFIELD at the same time.

Thank you very much for your advice.
Best regards,
