Working with UDP

    I try to work with UDP packets in Codesys V2. Which is the best library to use for reading and writing UDP packets ?

    Take a look at OSCAT Network. They have a codesys download for V2.3
    Their lib is open source, so you can either use their premade blocks, or look internally at their implementation.

      Thank you, I took a look. But not exactly matching, since they propose to use two blocks of NET_VAR on both sides, of PLC. However I will use gateway with UDP packet forwarder connected to PLC. I believe I needed to specify from beginning what is needed.
