EULow |
Defines the lowest value to set to the Value property, adjusting the scale to the value from the device before this attribution. Likewise, the inverse operation is performed before sending the value to the I/O Driver, when writing. This conversion happens only when EnableScaling property is set to True. Default value of this property is 0 (zero). Example:
Sub Tag_OnStartRunning()
' Adjusts the scale of temperature
' ranging from 0 to 255 at PLC, but it actually means
' 0 to 100 Celsius degrees
EU = "Celsius degrees"
EnableScaling = True
DeviceHigh = 255
DeviceLow = 0
EUHigh = 100
EULow = 0
End Sub
NOTE |
Bit values, the properties from Bit00 to Bit31, are not affected by adjustments in the scale, that is, they represent the bits from the value read by a device before conversion. |
