5.3
Digital Input / Output Descriptor
The DIO Interface provides 2 digital inputs that 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.

Note:
Please refer to the Smart Sensor Interface Technical Guide for more information regarding this descriptor.
5.3.2.1 Data Type
The 4-bit Data Type field determines the type of date of the specific sensor.
5.3.2.2 Factory Calibrate
The Factory Calibrate bit is not used for DIO types.
5.3.2.3 Sensor Writeable
If the Sensor Writeable bit is set the sensor value may be overwritten with a preset value. This capability is useful
in sensors such as up/down counters, where a preset, or possibly a zero value must be written to the sensor
value.
5.3.2.4 Smart Sensor
Refer to the Smart Sensor Device Interface documentation.
