    By the way Nicolas Chaillou how did you manage to write to the output table to a particular bit not the entire word for example change O:0/7 from 1 to 0 Best regards Hidroilio Pérez

  9. Micrologix 1500 DF1 Protocol Newbie

    Use this command on pag 7-17 protected typed logical read with three address fields CommandType = 15 Functionn = 162 BiteSize = 2 CommandToSend = Chr(16) + Chr(2) + Chr(RemoteNodeAddress) + _ Chr(DHNodeAddress) + Chr(CommandType) + _ Chr(MessageStatus) + Chr(TransactionNumber) + _ Chr(0) + Chr(Functionn) + Chr(BiteSize ) + _ Chr(FileNumber(Index)) + Chr(FileType(Index)) + _ Chr(ElementNumber(Index)) + Chr$(0) + _ Chr(16) + Chr(3) Remember to attach the check sum (CRC or BCC) to the command send Your respond should end in some thing like this DLE ETX CRC CRC Your data should be on the left side of DLE two bytes I used this code to extract it from the respond DecimalValue=256 * CLng(Asc(Mid$(Respond, Len(Respond) - 4, 1))) + CLng(Asc(Mid$(Respond, Len(Respond) - 5, 1))) Your respond would be the entire word 16 bits from there you have to pick the one that you are looking for example 0000101011100000 output 0:0/5 bit is one I use this code to get it Position:Position in the word of the bit that you want to read BitValue: bit that you want to read Private Function GetData(DecimalValue As Long, Possition As Long)    On Error Resume Next    Dim counter   As Integer    Dim TempValue As Long    Dim BinValue  As Byte    Do        counter = counter + 1        TempValue = DecimalValue Mod 2        BinValue = CStr(TempValue) + BinValue        DecimalValue = DecimalValue \ 2    Loop Until counter = Possition + 1    BitValue = TempValue End Function Hope this help Best regards Hidroilio Pérez
