How can i use libnodave.dll

[sinan]

hi everbody,

i am new user to visual studio 2008 ,c# ,  i could not  add  yo referance libnodave.dll in my console project, (i can add libnodave.net.dll  easly)  is there a special methot to use libnodave.dll,

i manage to connect with usb mpi cable with s7online test program is there any simple examle to usb mpi  porgram with c#

Thanks a lot,

In addition to establishing reference frameworks libnodave.net.dll in VS2008, libnodave.dll must be added in the same directory as libnodave.net.dll.

I have successfully connected via MPI cable. Attached is a sample function, but in VB

PS: If not connect in the first attempt, try again. In my case connected to the 2 nd attempt

    Private Function Conectar_MPI() As Integer
        Dim res As Integer
        Conectar_MPI = -1
        Try
            mfds = New libnodave.daveOSserialType() 
            mfds.rfd = libnodave.openS7online("S7ONLINE")
            mfds.wfd = mfds.rfd
            res = 0
            If mfds.rfd > 0 Then  ' if step 1 is ok 
                'Socket establecido
                'Establecemos el interface que representa la conexión fisica al PLC o a una red de PLCs 
                '--------------------------------------------------------------------------------------
                mdi = New libnodave.daveInterface(mfds, "Interface1",0, libnodave.daveProtoS7online, libnodave.daveSpeed187k)
                '  daveNewInterface(mfds, "IF1", localMPI, daveProtoXXX, daveSpeedYYY);
                ' LocalMPI y daveSpeed solo tienen sentido para conexiones MPI y profibus
                mdi.setTimeout(1000)  ' Make this longer if you have a very long response time
                'Establecemos ahora la conexión lógica al PLC
                mdc = New libnodave.daveConnection(mdi, 2, 0, 2)  ' rack amd slot don't matter in case of MPI
                 '    mdc =daveNewConnection(mdi, MPI_address, Rack, Slot);
                'Ahora conectamos
                res = mdc.connectPLC()
                If res = 0 Then
                    mEstadoConexion = eEstadoCommPLC.Conectado 'Conectado
                Else
                    mdc.disconnectPLC()
                    libnodave.closePort(mfds.rfd)
                    mEstadoConexion = eEstadoCommPLC.Desconectado 'Desconectado
                End If
            Else
                mEstadoConexion = eEstadoCommPLC.Desconectado 'Desconectado
            End If 'mfds.rfd >0
            If mEstadoConexion = eEstadoCommPLC.Conectado Then 'Conectado 
                Conectar_MPI = 0
            End If
        Catch ex As Exception
            'tratar aqui el error msgbox ex.description
        End Try
    End Function
