The values of analog inputs are updated each time you click "update". Register data is produced by applying respective slope and intercept to raw data read from hardware. Change input type and scale factors in I/O Setup->Analog Inputs.

The nature of data displayed will depend on channel configuration. When configured for analog, data will be scaled floating point. If a thermistor input is selected, integer data will be linearized degrees times 100. If discrete input is selected, the value will be either 0 or 1.

Floating point data will reflect degrees (C or F) when configured for thermistor input. Voltage readings will be normalized to 10.0 volts. Discrete readings will be 0 or 1.  Slope and intercept are applied after linearization or normalization.
