    Hallo,

    is there a chance to get the data with milliseconds?

    Thanks

  • sure… when you call opc.read(), be sure to include the update parameter.  update is measured in milliseconds, just as timeout is measured in milliseconds.

    example…

    python>> my_group = opc.read(tags=SOMEARRAYOFTAGS, group=SOMEGROUPNAME, timeout=INTEGERVALUEMILLISECONDS, update=INTEGERVALUEMILLISECONDS, sync=False)

    then, everytime you poll "my_group", it will refresh…  so you would simply create a loop that would poll it every however many milliseconds…
