Identifies the engineering unit represented by this value, such as degrees, meters, or KW/h. Default value of this property is empty. Example:

Sub Element_OnStartRunning()
  ' Performs a scale adjustment of an
  ' Element's temperature
  ' ranging from 0 to 255 on OPC server,
  ' but it actually means
  ' 0 to 100 Celsius degrees
  EU = "Celsius degrees"
  EnableScaling = True
  DeviceHigh = 255
  DeviceLow = 0
  EUHigh = 100
  EULow = 0
End Sub
