5.2
Digital Input / Output Descriptor
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 DIO Input descriptor is at base addresses
0x0068.
0x04..0x08
5.2.1 DIO Sensor Type

Note:
Please refer to the Smart Sensor Interface Technical Guide for more information regarding this descriptor.
5.2.2.1 Data Type
The 4-bit Data Type field determines the type of date of the specific sensor.
5.2.2.2 Factory Calibrate
The Factory Calibrate bit is not used for DIO types.
5.2.2.3 Sensor Writeable
If the Sensor Writeable bit is set the sensor value may be overwritten with a preset value.
5.2.2.4 Smart Sensor
Refer to the Smart Sensor Device Interface documentation.
