    Hi,

    I'm using 0.8.4.5. I can have 20 open connections, but no more than 20. Is it a theoretical limit, or is it a limit on libnodave? Is it possible to bypass it somehow?

    Thanks for your help! Waiting for your answer,

    Miki

    It's a limit of the PLC and the ethernet module.

    This is my experience:

    S7-200  1 connection
    S7-300 some modules 8, others more than 16
    S7-1200  4 connections

    Hi,

    Thanks for your reply. I have another question: how can I use Siemens' USB MPI cable (6ES7 972-0CB20-0XA0) with libnodave?

    Thanks,

    Miklos
