I was able to get listen mode working perfectly with this example, and reading operands looks fairly straightforward, though I've not integrated that just yet. Thank you so much Saragani!

I'm actually not familiar with plc.readwrite, are their any examples on the forms somewhere, or maybe an API i could work with. im trying to get listen mode to work as well (cant seem to get my program to actually LISTEN on a port)? i was not able to find any detailed documentation on ether subject for .net, though admittedly i may be looking in the wrong places. thank you for your help!

I've created a fairly workable application to retrieve data from the data tables of the PLC's (PL-570) i'm working with, however I would like to also be able to gather all of the operands (MB, MI, SI, etc) as well, and format them into organized datagridviews in vb.net. I'd like to use a similar method as I've used for the tables if possible: Public Sub ReadDataTables(IP As String, port As Integer, protocal As EthProtocol, retries As Integer, timeoutMs As Integer) Dim frmClockTables As New Form Dim Tabs As New TabControl frmClockTables.Controls.Add(Tabs) Tabs.Dock = DockStyle.Fill Try ethernet1 = New Ethernet(IP, port, protocal, retries, timeoutMs) plc1 = PLCFactory.GetPLC(ethernet1, 0) dtTables = New DataTables(plc1, DataTablesReadOptions.StructureAndValues) Catch ex As Exception MessageBox.Show("Could not connect to " & IP & " on port " & port) End Try Try ethernet1 = New Ethernet(IP, port, protocal, retries, timeoutMs) plc1 = PLCFactory.GetPLC(ethernet1, 0) dtTables = New DataTables(plc1, DataTablesReadOptions.StructureAndValues) Catch ex As Exception MessageBox.Show("Could not connect to " & IP & " on port " & port) End Try Dim colcount As Integer = 0 Dim rowcount As Integer = 0 For Each item In dtTables.Tables Dim data As New DataGridView Dim tab As New TabPage tab.Text = item.Name.ToString tab.Controls.Add(data) data.Dock = DockStyle.Fill Tabs.TabPages.Add(tab) colcount = item.Columns.Count rowcount = item.Rows.Count Dim i As Integer = 0 For Each column In item.Columns data.ColumnCount = colcount data.RowCount = rowcount data.Columns(i).Name = column.Name.ToString For Each Cell In column.Cells Dim cellvalue As String = "" For Each Field In Cell.Fields If Not cellvalue = "" Then cellvalue &= ";" End If cellvalue &= Field.Value Next data.Rows(Cell.RowIndex).Cells(Cell.ColumnIndex).Value = cellvalue Next i += 1 Next NumberAllRows(data) Next frmClockTables.Show() End Sub how can this be done, or can it be done at all?
