  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.

Thanks,

Yongzhi

  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: 192.168.1.1
- SUBNET: 255.255.255.0
- Gateway: 192.168.1.1
- DNS: 9.9.9.9

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)

Routes:
- 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,

Carsten


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

Hello,

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,
Johannes


  "ready to use" or "open platform" ... it's your choice

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.

   

More detailed info will follow shortly

  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 1.2.2.0 and 1.2.1.0.
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"

Can't open /root/.node-red/node_modules/node-opcua-client/certificates/client_selfsigned_cert_2048.pem.csr for writing, No such file or directory

1996263440:error:2006D080:BIO routines:BIO_new_file:no such file:../crypto/bio/bss_file.c:76:
====================

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.
Best regards,

  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,
