Hi Mahoodia, The information you are referencing were a result of my effort in reverse engineering the protocol. I had limited time and limited access to the setup I used for doing this.
In general I had a Profinet Simulator where I could define the values the Simulator sent to the PLCs and a Delta-V system on the other side wich consisted of a server and 3 Delta-V controllers. So I tweaked the input and listened to the output. But as it was our goal to passively interpret an oncoing Delta-V communication, I didn't need to decode all bits of the protocol. Of course, if you want to actively communicate with such devices a lot more work has to put in. If you have access to such a Delta-V system and are willing to put in some work, I'd be happy to assist you with continuing to work on this. But it could probably be that there are checksums involved which would require finding out how they are calculated and in the worst case even cryptographic hashes (which I personally doubt), which would make it even more difficult.

I am looking for the structure and format of receiving and sending udp protocol from Deltav Emerson Company. That's why I read the following link https://plc4x.apache.org/protocols/delta-v/ , but unfortunately due to the good information it has given us. But he did not give me any information about exactly how Emerson received and sent the format. Thank you very much for your information thanks
