連接多個控制器的範例程式

下節說明使用.NET應用程式將PC連接到控制器1和控制器2的範例程式。

提示

有關可使用的屬性與方法，請參閱以下內容。

控制連線設定

同時連接至多個控制器時，使用Spel類別的Connect方法指定連線。

m_spel.Connect(1)

Connect方法中的參數代表連線編號。此數字與下方對話方塊中「Number」中所示的數字相同(Epson RC+ 8.0功能表-[Setup]-[PC to Controller Communications])。如果數值使用-1，表示使用最近的連線。

專案設定

若要連接多個控制器，請使用Spel類別的Project屬性指定專案。每個控制器都必須使用獨立的專案。

m_spel.Project = "c:\EpsonRC80\projects\API_Demos\Demo1\Demo1.sprj"

使用Visual Basic的範例程式

在Visual Studio .NET中，選擇功能表-[File]-[New]-[Project]。
建立Visual Basic專案。
選擇功能表-[Project]-[Add Reference]。
選擇[瀏覽]標籤，參照「(Program folder)\API\Assembly\net462」目錄，然後選擇「RCAPINt2.dll」檔案。
添加兩個按鈕(btnController1、btnController2)至Form1類別。
添加各按鈕的快速事件，並建立執行緒以控制各個機器人控制器。

Private trd1 As System.Threading.Thread    ' 機器人控制器1  
Private trd2 As System.Threading.Thread    ' 機器人控制器2  
  
Private Sub btnController1_Click(ByVal sender As System.Object, _  
ByVal e As System.EventArgs) Handles btnController1.Click  
      ' 啟動機器人控制器1的執行緒  
      trd1 = New System.Threading.Thread( _  
New System.Threading.ThreadStart(AddressOf StartController1))  
      trd1.Start()  
End Sub  
Private Sub StartController1()  
    ' 控制機器人控制器1  
    Try  
       Dim frm1 As New frmDemo1  
       frm1.ShowDialog()  
       frm1.Dispose()  
    Catch ex As Exception  
       MsgBox(ex.Message)  
    End Try  
End Sub  
Private Sub btnController2_Click(ByVal sender As System.Object, _  
ByVal e As System.EventArgs) Handles btnController2.Click  
     ' 啟動機器人控制器2的執行緒  
     trd2 = New System.Threading.Thread( _  
New System.Threading.ThreadStart(AddressOf StartController2))  
     trd2.Start()  
End Sub  
Private Sub StartController2()  
    ' 控制機器人控制器2  
    Try  
       Dim frm2 As New frmDemo2  
       frm2.ShowDialog()  
       frm2.Dispose()  
    Catch ex As Exception  
       MsgBox(ex.Message)  
    End Try  
End Sub

Private Sub frmDemo1_Load(ByVal sender As System.Object, _  
ByVal e As System.EventArgs) Handles MyBase.Load  
  
     Try  
        m_spel1.ServerInstance=1  
        m_spel1.Initialize()  
        m_spel1.Connect(5)  
        m_spel1.Project = " c:\\EpsonRC80\\Projects\\Demo1\\Demo1.sprj "  
     Catch ex As SpelException  
        MsgBox(ex.Message)  
     End Try  
End Sub  
Private Sub m_spel1_EventReceived(ByVal sender As Object, ByVal e As  
 SpelEventArgs) _Handles m_spel1.EventReceived  
    ' 機器人控制器1  
End Sub  
Private Sub frmDemo1_FormClosed(ByVal sender As System.Object, _  
ByVal e As System.Windows.Forms.FormClosedEventArgs) _  
Handles MyBase.FormClosed  
    m_spel1.Dispose()  
End Sub

添加控制器2的表單(frmDemo2)。

Private WithEvents m_spel2 As New Spel  
Private Sub frmDemo2_Load(ByVal sender As System.Object, _  
ByVal e As System.EventArgs) Handles MyBase.Load  
  
    Try  
       m_spel2.ServerInstance=2  
       m_spel2.Initialize()  
       m_spel2.Connect(6)  
       m_spel2.Project = " c:\\EpsonRC80\\Projects\\Demo2\\Demo2.sprj "  
    Catch ex As SpelException  
       MsgBox(ex.Message)  
    End Try  
End Sub  
  
Private Sub m_spel2_EventReceived(ByVal sender As Object, ByVal e As  
SpelEventArgs) _Handles m_spel2.EventReceived  
    ' 機器人控制器2  
End Sub  
Private Sub frmDemo2_FormClosed(ByVal sender As System.Object, _  
ByVal e As System.Windows.Forms.FormClosedEventArgs) _  
Handles MyBase.FormClosed  
    m_spel2.Dispose()  
End Sub
