Configure universal I/Os

  1. On the Device Configurator page, right-click on a universal I/O terminal to be configured, for example, X1.
  1. Configure the following parameters according to the actual application in the pop-up window:
  • Point Name: Enter an easily identifiable I/O name in the text box on the right. When completed, the corresponding terminal turns green.
  • Description: Shortly describe the I/O in the text box on the right.
  • Unit: Enter the measurement unit.
  • SignalType (Required): Select a correct signal type in the drop-down menu on the right.
  1. If signal type In_0-10V, Out_0-10V, In_0-20mA or In_4-20mA is selected, the following options are displayed:
  • SignalRangeMin: Enter the min. value of the signal range.
  • SignalRangeMax: Enter the max. value of the signal range.
  • MeasureRangeMin: Enter the min. value of the measurement range.
  • MeasureRangeMax: Enter the max. value of the measurement range.
