You should download this VB.Net source code and see how it communicates with UDP then do the same in your application. http://forums.mrplc.com/index.php?app=downloads&showfile=992 Also, download the following pdf file for details on FINS command. http://forums.mrplc.com/index.php?app=downloads&showfile=620 These are the only 2 links you need to be a FINS expert.
