  NetHat + Ethernet/IP + APIs or SDKs
Posted by: michela.limaco - October-8th-2021, 07:29 PM - Forum: Software - Replies (4)


I am trying to use NetHat with Raspberry Pi2.

I installed Driver and Firmware for Ethernet.

Would you like to know if there are libraries or SDKs for java or C++?

And if there is any knowledge base with examples such as sending data through a GET/POST request.

Thank you in advance.

  Configuring EtherCAT communication
Posted by: Hoeber - September-22nd-2021, 01:11 PM - Forum: Projects - Replies (1)

Hello Armin,

I am trying to run the netPi as an EtherCAT slave. I want to connect the netPi to the EtherCAT system of a machine where I need an Input and Output of 100 bytes each.
I used the netX example codes and changed the size of uint8_t abApp_Inputdata[10] and [i]uint8_t abApp_Outputdata[4][/i] to uint8_t abApp_Inputdata[100] and abApp_Outputdata[100] in "examples/includes/App.h". I also adapted the "Hilscher ECS LFW Host Example Simple Config.xml" by changing the DefaultSize of Inputs and Outputs from 10 and 4 to 100. Here, I also continued the RxPdo and TxPdo up to 100.

When I now run the application ECS_simpleConfig I get the following notification:

Register application failed Error: 0xc0000201
Error: 0xc0000201, <>
Error stopping the watchdog lRet = 0x800c0012!!

According to the documentation, the errorcode 0xc0000201 says that the "application ist already registered" and the errorcode 0x800c0012 means that the "communication channel ist not configured".
Does this indicate that there is a problem registering the slave with the master, meaning I made a mistake when customizing the xml file? Or have I missed a variable or something else in another file that I still have to change?

Or have I taken the whole thing too easy in the first place and it takes much more than just customizing the example files?

Thanks in advance!


  netPI DIN Rail Clip

Hi Forum

Does anyone have a photo, or drawing of the netPI mounted on a DIN Rail so we can see how the clip works and it's height relative to the rail?

Thanks in advance.

  NetPI wifi access to WPA2-Enterprise
Posted by: MikeP - September-2nd-2021, 10:18 PM - Forum: Software - Replies (4)

newbi question here...

I am starting to experiment with the WIFI interface of my netPI [NIOT-E-NPI3-51-EN-RE]  

From control panel, I can  successfully set it up as an access point and connect to it from other wifi clients.

However, I'd like to set it up as a wifi client on the corporate network, which has WPA2-Enterprise SSIDs that require both an id and a password.   When I select one of these SSIDs from the netPis control panel, it prompts only for shared key.    [that is, it prompts only for password, not id and password, even though it displays the SSID as type  WPA2-Enterprise [WPA2 802.1X]       

Is there a way to specify connection to this SSID?

  USB Port Mapping
Posted by: DSongra - August-24th-2021, 07:22 AM - Forum: Software - Replies (3)

Dear Armin,

Hope you are doing well!

I am working on Modbus RTU node red in our NetPi RTE Gateway using RS485 to USB converter, but not able to mapped the USB port in node red docker container, as we have already done this successfully in last year (thread-653) I have referred this same.

I am getting error while creating the Docker Container if I add "/dev/ttyUSB0" in Devices attached screenshot for your reference.
