For more details on physical connection of IO points see the “Inputs” section of the Edge 10 Mounting and Wiring Guide.
The EdgeIo driver provides proxy points to access these points.
To use the EdgeIo driver add an EdgeIoNetwork object to the station config folder (already installed in the default station). The EdgeIoNetwork contains a Local device with a Points folder. Invoking the Edge Io Point Manager Discover function shows a list of available points, as shown here.

Proxy points can be configured through the Add/Edit functions in the Edge Io Point Manager.
For UI points set the Type to an AI (NumericPoint), DI (BooleanPoint) or pulse counter (pulseInput).
For Pulse Counter type inputs, edit the proxy point to configure Calc Type, Rate Scale, Rate Interval and Rate Windows properties. More details on this will be available in a EdgeIo Guide (not currently available).
