DIO Interface
The DIO Interface provides 2 digital inputs which are hardwired to the Digital outputs. These may be used to detect
the state of external switches (output off) or to monitor the state of the outputs.

The 4-bit Data Type field determines the type of data of the specific sensor.
The Factory Calibrate bit is not used for DIO types.
This indicates that the sensor value may be overwritten. Not used on DIO inputs.

If set, the user-specified units of measure string (4 character maximum) will be used in place of
the default DIN.
If set, the user-defined Offset and Gain values will be used to adjust the sensor reading:
