This property defines the highest value reached by an OPC Block Element in the device. This property is used to perform a scale adjustment of the value from a device before setting it to the Value property. Likewise, at the moment of a writing the inverse operation is performed before sending the value to the Driver. This conversion only occurs when the EnableScaling property is set to True. Default value of this property is 1000. 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
