Tag.DataType Property

Returns one of the enumerated Tag.ATOMIC types.

Example

VB


Try
  ' ********************************
  ' * initialize controller and tag
   Dim MyPLC as New ABLink.Controller("192.168.1.32", CPU.SLC, Driver.ENET)
   Dim MyTag as New ABLink.Tag("N7:0")
   ' *******************************
   ' * Read tag
   MyPLC.ReadTag(MyTag)
    
   ' *******************************
   ' * check the status
   If ResultCode.QUAL_GOOD = MyTag.QualityCode Then
      Console.WriteLine(MyTag.Timestamp.ToString())
      Select Case MyTag.DataType
        Case ATOMIC.BOOLEAN)
          Console.WriteLine("Tag is Boolean")
        Case ATOMIC.INTEGER
          Console.WriteLine("Tag is Integer")
        Case ATOMIC.LONG
          Console.WriteLine("Tag is Long")
        Case ATOMIC.FLOAT
          Console.WriteLine("Tag is Float")
        Case ATOMIC.STRING
          Console.WriteLine("Tag is String")
        Case ATOMIC.ASCII
          Console.WriteLine("Tag is Byte")
      End Case              
   Else
      Console.WriteLine(MyTag.ErrorString)
   End If
   
   Console.WriteLine(MyTag.QualityString)
Catch ex As System.Exception
   Console.WriteLine(ex.Message)
End Try
