For boolean “universal input” type NrioBooleanPoint (BooleanInputPoint).
For numeric “universal input” types NrioCounterPoint, NrioResistivePoint, NrioThermistorPoint, and NrioVoltagePoint. (CounterInputPoint, ResistiveInputPoint, ThermistorInputPoint, VoltageInputPoint)
For for boolean output type NrioRelayOutput (RelayOutputWritable).
For numeric output type NrioVoltageOutput (VoltageOutputWritable).
Each Nrio point type is typically unique by one or more properties in its proxy extension. Also, the proxy extension in each type contains the same (common) properties. Things unique to each Nrio point type are explained in following sections, as well as common properties in each point’s proxy extension.
