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. In most cases, the integer data (Int Data) will be the raw counts from the A/D converter. If a thermistor input is selected, integer data will be linearized degrees times 100. If discrete input is selected, the integer (raw data) 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 10.  In all instances, slope and intercept are applied after linearization or normalization. Therefore the displayed data may not necessarily be in the range of 0 to 10.0. It can be scaled to any engineering units range.

The inputs displayed on this page may be read via Modbus or SNMP. The Modbus holding register number is shown in the first column. SNMP OID's are a prefix with this register number added on.
