EYFR03 User Manual 59 of 110 v1.6.0Chapter 5: Discrete I/O 20 January 2020Assigning I/O FunctionsThe inputs and outputs must be configured before use. By default, the unit does not ship withany relay configuration. To configure the inputs and outputs, you will need to use the PCsoftware application.I/O StatusFigure 53: I/O Status screenThe I/O Status screen shows the current state of the physical inputs and outputs to the EYFR03.If you have not configured the I/O, this screen will just say “I/O not configured” instead ofshowing the inputs and outputs as pictured above. If you have configured the I/O and this screenshows another message, please contact product support.Once the I/O is configured, the screen will show the state of each input. A high input or outputwill be filled in with green. A low input or output will be filled with yellow.InputsThe inputs of the EYFR03 qualifier take 3.3-24VDC and have low current drain. The discreteI/O has a single common pin for all inputs and a signal pin for each input. The inputs can beused to select an item to run or control the qualifier.The selection inputs should not be used when the unit is being controlled by a network protocol,as this will generally result in unexpected behavior. Some control inputs, notably the suspendinput, may also cause unexpected behavior when used along with a network.Selection inputsSelect Parameter #XInputs used: 1 per parameterThis input selects a parameter when activated. One version of this input exists for each of the100 available parameters (Select Parameter 1, Select Parameter 2, etc.). If the parameter is notconfigured with a valid tool, activating an assigned input will do nothing. Deactivating the inputdoes not stop the parameter. The parameter will remain selected until the parameter is stopped,or another parameter, group, or job is selected.
