FZ_FormBase.GetAll

Performs a batch input of the state of terminals such as the parallel I/Os

Public Shared Function GetAll( _
   ByVal ioIdent As String, _
) As UInteger

Parameters

ioIdent

Type of acquisition destination
ParallelIo: Parallel I/O
SerialNormal: Serial non-procedure communications
UdpNormal: Ethernet UDP non-procedure communications

Input

Return Value

Returns the terminal state from DI 0 to 7.

Description

Gets a terminal state from DI 0 to 7 when ParallelIo is specified.

The processing of this method is disabled for other I/Os.

Example

    Private ANDBIT As UInteger = 1

    Private Sub Form_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

        'Get the status of ParallelIO.
        Dim sData As UInteger = GetAll("ParallelIO")
        Dim bit(7) As Boolean
        For i As Integer = 0 To 7
                bit(i) = CBool(sData And ANDBIT)
                sData >>= 1
        Next
        'The status of ParallelIO is reflected.
        If bit(0) = True Then
                'Suitable processing is put in here. 
        Else
                'Suitable processing is put in here. 
        End If
