It should works only since CODESYS V3.5 SP13.

So, Multicast is not functional in SP12?

Hello Edwin. Can you adjust your project above to enable Multicast instead of Unicast? I would like to have the sender data received by multiple receivers in a Multicast group. I've tried manipulating the .ipMultiCast and the .ipAddr but have not had any luck.

How can I add the data type UDPData to my project? I can't seem to find this "Structured Type" in any library.

Hi Edwin,

After some tests, i have found the problem - not the solution - .. When OLA service (https://www.openlighting.org/ola/) is running and setup as a ARTNET node for output DMX streams, the codesys code for decoding UDP data, stucks, no Peer is established..

If the OLA service is running in other raspberry different thant codesys is running, then UDP decode program works.. It seems _ service block connections on 6454 port (as we can see on snapshot)

Thanks for your support Edwin.

Hi Miquel,

if you give me some details on what I need to call/install for Qlcplus on Raspberry Pi
I would try to investigate the reason..

Hi Edwin,

I have been 'fighting' in my scenario... I have no found any reason to explain this issue. Sometimes it works, and suddenly it stops, and there is no peer !!

I have a raspberry running with app that you send me.
There is an app (Qlcplus on same Raspberry) that send traffic DMX to an ARTNET (ip) device on same subnet, port 6454.

I have try to generate DMX on other pc (stopping Qlcplus on Raspberry), and get traffic with your app, but also is no peer !!

Thanks for your support..

Regards,

Miquel

Hi Miquel,

after rechecked this.. in my case it does work always, never seen a false on Peer init.

How could we proceed?
Is there any other program which uses the port on the pi.
Is it possible to send me your artnet generator Software to check?

Hello Edwin,

Thanks for your reply..

I have checked your code, and it seems to work, but not always.. Most of times, Peer it doesn't initialize properly, it remains to FALSE. Connection to target is ok, no errors, there is traffic on 6454 port (i have a traffic artnet generator software), but socket is not open on Raspberry..

I have review all options, but i have no found any clue..
