hi I use a combination of two examples: 1. Unitronics SD Card Explorer Lite User Control 1.0.0.6 2. Unitronics Data Table (Image attachment with DLL files) Part of the "Unitronics SD Card Explorer" Works correctly Part of the "Unitronics Data Table" Fails on this line: dataTables = new DataTables(plc, DataTablesReadOptions.StructureOnly); Computer working properly with: VisiLogic and Z-View(HMI) ??????? What I'm trying to do is a program that performs automatic backup of tables (from PLC tables or SD-CARD) Are there any other tools that make the backup?

Thanks for the reply .Remains remained only message On WinXP PCs : "Cannect Comunicatioate with the PLC with the specifide UnitID" On the Win7 computers it works correctly. What caused the error? Thanks .

OK It seems that the problem is the use of components "Xceed.Compression.Formats.dll" How can Lhistams examples?

Helo The software on my computer running good but, Why when I run on another computer it gives the error message : "Cannect Comunicatioate with the PLC with the specifide UnitID" or sometimesI get the error message (I do not know when): Message an attachment try { if (plc == null) { Ethernet ethernet = new Ethernet("10.0.0.123", 20256, EthProtocol.TCP, 3, 3000); plc = PLCFactory.GetPLC(ethernet, 0); // Serial serial = new Serial(SerialPortNames.COM1, BaudRate.BR115200, 3, 3000, DataBits.DB8, System.IO.Ports.Parity.None, System.IO.Ports.StopBits.One); // plc = PLCFactory.GetPLC(serial, 0); } dataTables = new DataTables(plc, DataTablesReadOptions.StructureAndValues); dataGridView1.DataSource = null; updateTablesListAndGrid(); ReadRange.Enabled = true; WriteRange.Enabled = true; ReadTable.Enabled = true; WriteTable.Enabled = true; UpdateTable.Enabled = true; } catch (Exception ex) { MessageBox.Show(ex.Message); } Files: Data Tables DLL Example.exe Unitronics.ComDriver.DLL v1.0.0.33 Unitronics.DataTables.DLL v1.0.0.9 Xceed.Compression.dll Xceed.Compression.Formats.dll

Wow works great, thanks

Hello Is there any code examples or instructions on how to reading and writing of DataTables using C# Drive.NET Thanks

EX-RC1 is the second expansion unit of the v570 Total: In16 + Out16 + AI4 \ AO2 V260 transferring data to v570 : MI*8 + MB*10 V570 transferring data to v260: MI*10 + MB*10

network's structure: How does the Communication, Who sent to whom? As soon as there is no conflicts? (Not like a Master/Slave that manages all Master)

Thanks .... So simple!

I use an old PLC V260 and I want to convert the project to V570. How to do this?
