FZ_FormBase.ReceiveData

Performs an input of Byte type array data

Public Shared Function ReceiveData( _
   ByVal ioIdent As String, _
   ByRef inputData As Byte(), _
   ByRef inputSize As Integer, _
   ByVal parameter As Object, _
   ByVal parameterSize As Integer _
) As Integer

Parameters

ioIdent	Type of input destination ParallelIo: Parallel I/O SerialNormal: Serial non-procedure communications UdpNormal: Ethernet UDP non-procedure communications	Input
inputData	Input data	Output
inputSize	Input size	Output
parameter	Input condition parameter (optional) * In case of UdpNormal, specify the IP address (example: "192.168.0.1") of the connection destination to the parameter as a string. For other I/Os, do not specify the parameter as it is neglected.	Input
parameterSize	Input condition parameter size	Input

Return Value

Returns 0 when the data is successfully input.

Otherwise returns a non-zero value.

Description

Receives the data from the specified input destination.

Stores the received data into the array specified by argument inputData, and stores the received number of bytes into the variable specified by argument inputSize.

Example

    Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
 
       Dim size As Integer
       Dim data(256) As Byte
       Dim value As String

       ' Inputs the data on parallel
       ReceiveData("ParallelIO", data, size)

       ' Inputs the data on serial
       ReceiveData("SerialNormal", data, size)

       ' Inputs data on Ethernet UDP
       ReceiveData("UdpNormal", data, size, "192.168.0.1", 11*2)

       ' Transform the byte to string
       value = System.Text.Encoding.ASCII.GetString(data, 0, size)
 
    End Sub
