Read data from PLC DL 06 in c#

Question

Hi all,
Would you please give me an example, how I can read data from 3(three) PLC DL 06 simultaneously using RS232 and write it in 3 text files.
Eg.
0,1,0,0,0,1,0
0,0,1,1,0,0,0
1,1,0,0,1,0,1
Thanks in advance.
Triphon.

Normal 0 false false false EN-US X-NONE HE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; text-align:right; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} Ok, if you already have got your data, And keep it in byte array (as example) You want to save this data to text file? This is the Pease of cake in .NET! byte [] DataFromPLC = new byte [] { 1 , 0 , 2 , 3 , 4 , 5 , 1 , 222 , 1 }; // - anything StringBuilder resultData = new StringBuilder (); // let say that we will recive a lot //of data - so it better vay to work with long strings foreach ( byte oneByte in DataFromPLC ) { resultData . Append ( oneByte ); resultData . Append ( "," ); // separator } System . IO . File . WriteAllText ( "c:\test.txt" , resultData . ToString ());

I want to know is there anything more from taking the IP address of the plc and then read tata from plc's memory. If so, I have no problems, because I know how to do this, but if it is needed anything more then I need a help. That's why I want something which will guide me, may be not 100%. Regards, Triphon.

Could you ask more concentrated? What exactly you don't understand?
