Data type
Element
Description
0-1
Float
Value
Measurement value
2
Unsigned8

For more information see main operation manual. Basically the same connections for device variables are
equivalent to the connections available for analog input and outputs:
A device variable AO corresponds to a current input and typically has the same connection possibilities.

Each DO device variable consists of the following elements:
Register-Offset
Data type
Element
Description
0
Unsigned8
Value
0 (false) or 1 (true)
1
Unsigned8
Status
Validity of value, see 0
The mapping of DO device variables is done in the manner described for AO device variables.
Path: The device variables are selected in the menu of the function that uses the actuating value.
