Posted by: MGharat - December-9th-2019, 01:20 PM - Forum: Projects - Replies (6)

I have compiled the below image 

  • hilschernetpi/netpi-netx-programming-examples
After excecuting ethercat slave examples, I get as below output as attached screenshot --is it the correct? EtherCAt interface is ready to use ?
Also how I can get ESI file ? I checkd t github..but how I can take it for download into Master?

Thanks & BR

  tcp/ip udp to EIP converter
Posted by: milesie - December-4th-2019, 01:56 PM - Forum: Projects - Replies (1)

Hello Forum

My customer want's to read netPI from his Ethernet/IP master.
so netPI RTE with Ethernet/IP adapter.
on the netPI standard Ethernet interface he wants to have a TCP/IP UDP connection where he gets about 1K of data.
embedded in the ethernet frames are his interesting process data to transfer to the EIP.
Can he do that, how? With what applications would he load into Docker?
and what sort of performance can he expect?
It's a machine control PLC type application so he expects quicker than 50mS update time.


  Starting example cifxlinuxsample.c on Raspberry Pi
Posted by: Christian - December-2nd-2019, 11:18 AM - Forum: Software - Replies (4)

Hello everybody,

at the moment I test the Hilscher NetHat for a Ethercad solution in my Masterthesis.
First I test the getting started documentation on the version V1.0.0.1

My Problem ist, that I can´t start the testprogramm cifxlinuxsample.c on the Raspberry Pi
The compiler publish a fatal error. The data cifxlinux.h can´t be find.

In the download I can find the cifXEndianess.h Data but not the cifxlinux.h.

Can everybody help me? What I am doing wrong.

  C Compiler

I want to test the netHAT.
Can you recommend a compiler to use for the example C in the manual?
The programs I have used before are written in Python, do you have that example also in Python instead of C?

  Zuführungssystem mit netPI RTE 3
Posted by: pstern - November-26th-2019, 09:51 AM - Forum: Projects - Replies (5)

Guten Tag
Für meine Diplomarbeit an der FHNW im Studiengang Systemtechnik, suche ich für ein neu entwickeltes Zuführungssystem eine Alternative zu der verwendetet Beckhoffsteuerung. Dabei ist vorallem der Platzbedarf ausschlaggebend. Zurzeit wird ein Schaltschrank verwendet, welcher mit der Weiterentwicklung verschwinden soll. Schnell habe ich mich für einen Raspberry PI Mikrocontroller entschieden. Dieser soll jedoch möglichst industrie- und ProfiNet-tauglich sein.
Nun bin ich auf Ihr Produkt netPI RTE 3 gestossen. 
Für mich wäre ideal, wenn ich mit ProfiNet arbeiten könnte. Weiter möchte ich die ganze Steuerung mit Codesys programmieren. Zusätzlich muss die Steuerung Schrittmotoren ansteuern und in der Lage sein, eine Bildverarbeitung durchzuführen (Teileerkennungskamera). Weitere I/Os sollten mit einem zusätzlichen I/O Modul abgedeckt werden.
Gibt es da eine Möglichkeit mit dem netPI RTE 3 zu arbeiten?
Vielen Dank für Ihre Antwort!

  Experimenting with 64bit Raspbian OS on netPI
Posted by: Armin@netPI - November-19th-2019, 12:28 PM - Forum: Projects - Replies (1)

Today I began experimenting with Raspbian OS on my netPI. Of interest was the 64Bit version specifically.

I programmed my micro SD card with the latest version Raspian OS, 2019-09-26: https://downloads.raspberrypi.org/raspbian_lite_latest first.

The only thing I did was then to insert the term


in the config.txt file, pushed the card into the netPI (#REV2 with unseald SD card slot) SD card slot and booted netPI. A quick check on the console using

uname -a

showed "aarch64" ARM64 instruction set is active. WOW! That was easy.

After that I installed Docker and the Docker web UI portainer.io with

apt update
curl -sSL https://get.docker.com | sh
docker volume create portainer_data
docker run -d -p 9000:9000 -p 8000:8000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

Accessing the web UI at <netPI IP address>:9000 let me deal with Docker quite easily like I am use to on original netPI Hilscher OS.

I started two debian containers from Docker Hub. One 32Bit and one 64bit version.


In both containers I installed the tool sysbench (version https://github.com/akopytov/sysbench/arc....17.tar.gz to be exact) and check the CPU speed with

sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run

Here are the results:

CPU speed:
   events per second:    74.27

General statistics:
   total time:                          10.0493s
   total number of events:              747

Latency (ms):
        min:                                   53.10
        avg:                                   53.77
        max:                                   75.04
        95th percentile:                       53.85
        sum:                                40162.56

Threads fairness:
   events (avg/stddev):           186.7500/0.43
   execution time (avg/stddev):   10.0406/0.01

CPU speed:
   events per second:   937.13

General statistics:
   total time:                          10.0037s
   total number of events:              9381

Latency (ms):
        min:                                    4.22
        avg:                                    4.26
        max:                                    9.81
        95th percentile:                        4.25
        sum:                                39993.05

Threads fairness:
   events (avg/stddev):           2345.2500/0.83
   execution time (avg/stddev):   9.9983/0.00

The counted events in 64Bit mode are 12.7 times higher. In turn this means the sysbench code sequence is executing around 12 times faster. 2nd WOW!! That is fast.

Of course I cannot exclude that this performance boost is somehow related to the sysbench tool itself that no relation to real applications. And also please keep in mind that sysbench was just calculating prime number during the tests. In no way this test represents and overall performance test that would cover also a memory benchmark and a disk benchmark (SD card). I found another thread that sets 64Bit and 32bit examinations in relation. The author came to 15 to 30% performance boost:https://www.cnx-software.com/2016/03/01/64-bit-arm-aarch64-instructions-boost-performance-by-15-to-30-compared-to-32-bit-arm-aarch32-instructions/

  Profinet Startup Time
Posted by: Schranz - November-18th-2019, 09:03 AM - Forum: Software - Replies (3)

I use a netPI RTE 3 as profinet client. Up to now I did use one container running NodeRed for communication and calculation. With this setup the netPI profinet client was available below 50 seconds after power on.
Now I use two containers one with NodeRed doing the communication and one with Python doing the math. With this setup it takes 210 seconds until the the profinet client is available after power on.

Could I start the container with NodeRed doing the communication first?
Is there a way to have the profinet client ready with defaults independently of running containers?
Other ideas?

Any help is appreciated
