  Pi + netHAT + NodeRed + EtherCAT
Posted by: effendi - August-19th-2021, 09:14 AM - Forum: Software - Replies (1)

For integrating a custom measurement device via EtherCAT, we are planning to use a Raspberry Pi equipped with netHAT.

Is there any way to have communication integrated into an existing Node-Red project, so that we can send commands and receive sensor values via EtherCAT?

Any help or suggestion is highly appreciated.
Thank you very much!

  Software difference netIOT Connect vs netFIELD Connect
Posted by: HeinzeS - August-11th-2021, 04:03 PM - Forum: Software - Replies (3)

Hi Armin,

at our development Team we procured several netPi devices. So we currently have a bunch of:

as well as

The netfield devices were easily updated to the current v2.2.0.0 OS version of netFIELD OS and are behaving as expected. The netIOT Connect devices are running v1.2.0.0 netPI OS and currently have some problem running newer versions of grafana dockers (>7.5.4), which are running fine on their netFIELD OS "brothers". We suspect the restricted docker engine 18.X to cause those problems. Can you elaborate the situation?

Best regards

Exclamation We are short on netPI RTE 3 - new gateway is coming
Posted by: Armin@netPI - August-11th-2021, 08:18 AM - Forum: News - Replies (1)

Chip shortages are in everybodies mouth these days. Even cars cannot be produced any more cause embedded chips/controllers are out of stock.

So as with netPI. Maybe one or the other has already heard it from press releases but company Broadcom as the Raspberry PI CPUs chip manufacturer does not deliver Raspberry Pi 3 CPUs till estimated Q2/2022. This is really challenging us and especially you as our customers.

netPIs are getting out of stock and we feel really sorry about to say that until we do not get better news on the latest CPU delivery time information - communicated to us just 4 weeks ago recently - we are held to communicate to you Q2/2022 as the official time the next batch of netPIs are produced. 

Nevertheless for repair cases we have still spare units in stock and reserved for such cases. 

Here are some related news you find on the web about the current chip situations worldwide:


  HTTP Request using Nodered
Posted by: DSongra - August-10th-2021, 06:22 AM - Forum: Software - Replies (6)

Dear Armin,

Good Morning.

Hope you are doing well.

I am working on HTTP Request application to fetch the data from Amadeus8 Software, some of the Get request working and some of the not. for cross checking request I have used Postman Software for checking the same HTTP Get Request and it is working fine with Postman Software, but in node red it is not working.

Is there any Docker Container need to be install?

  Node red web UI issue
Posted by: DSongra - July-22nd-2021, 12:53 PM - Forum: Software - Replies (3)

Dear Armin,

I am using NetPI RTE gateway installed node-red using docker container.

I am facing two major issues most of the time.

1) Node-red web UI run for 1 hour only then it is asking to put login ID & Password if we are doing any changes in between and we do not deploy node-red flow then it got lost the node configuration settings.

2) Node-red web UI not opening giving error as "This site can't be reached". even after restarting docker node-red container and NetPi Gateway also, but still facing this same issue. (attachment 1). 

Is there anyone who has this type of same issue facing while testing?

Posted by: DSongra - July-22nd-2021, 12:04 PM - Forum: Software - Replies (9)

Hello Armin,

I have installed node-red using the docker container in the netPI RTE Gateway. For the OPC UA server I am installing hilschernetpi/netpi-opcua-server container but am stuck at Volumes > Volume mapping > map volume setting. it is not showing Volume to select or edit to add "certs" volume.

I have followed the steps. (attachment 1).

Not able to set/define. (attachment 2).

Please help me to solve this issue and proceed further.

  Welcome "sensorEDGE" as new subforum
Posted by: Armin@netPI - July-21st-2021, 11:24 AM - Forum: News - No Replies

We opened a new forum for the solutions called "sensorEDGE".

The brand sensorEDGE stands for a hybrid edge-cloud ecosystem. It consists mainly of IP67 rated boxes with edge computing power and optional cloud connectivity and service offers.

The first set of sensorEDGE boxes we are about to release in September 2021 will be those with IO-Link master support for up to 8 local ports. These "Edge IO-Link master" boxes lift IO-Link instrumentations to the next level by pairing IO-Link, Edge and Cloud support in one solution.

Two Ede IO-Link masters will be available. 

1. One is named "sensorEDGE" - like the brand name - and is described as "Plug-and-play over the globe IO-Link sensor data provisioning solution". Read on for more details here https://www.hilscher.com/netfield/sensor...Lang=false

Here is the broschure: 
.pdf   PD-netFIELD-sensorEDGE_07-2021_GB.pdf (Size: 316.48 KB / Downloads: 2)

2. The other is named "sensorEDGE FIELD" and described as "Do-it-yourself application open IO-Link master edge computing platform". Detail will be published later the year.

  REST API server data communication
Posted by: MGharat - July-20th-2021, 12:17 PM - Forum: Software - Replies (2)

Hi Armin,

one of our customer wants to use REST APIs & communicate with his server software . Further this  server data is to be passed to an OPC UA client through our netPI gateway.

I attached herewith customer software RESET API document for your reference.

Can we use here netPI RTE to collect data from customer server ( over eth0) REST API communication & then transfer it to OPC-UA ( over Fieldbus port) ?

  Node-RED 'projects' possible on netPI?
Posted by: JG_KIT - July-15th-2021, 09:25 AM - Forum: Software - Replies (2)


I thought of using the 'projects' feature of Node-RED to save my flows on GitHub.
I found tutorials saying, that setting this variable:
will work an apparently it does try:
however, fails when trying to find 'git'.

So, I wondered, is this image of Node-RED that is supplied under 'HilscherAutomation/netPI-nodered' on GitHub able to use projects (has git included) and I am doing something wrong or do I need another option than that to back up the content of my Node-RED container (and possibly import them on other netPI devices)?

Thanks a lot in advance.

Best regards,
