Functions
The module AI4 12Bit / AO4 16Bit has 4 analog inputs and 4 analog outputs. All channels can be
parameterized almost independently of each other, giving the module a high degree of flexibility.
Input and output values can be easily scaled according to their use so that, for example, the measured value
of a sensor can be read directly in the desired unit.
Configuration examples
Input mapping
Depending on the configuration of the analog inputs, various predefined mappings are available.
A basic distinction is made between the following display formats:
-
Field Value Physical: Input value in [V] or [mA] as REAL
Mapping 1A01
h
active
-
Field Value Increments: Input value in digits as UINT
Mapping 1A02
h
active
-
Process Value: Scaled input value (Process value) as REAL
Mapping 1A03
h
active

Using the analog inputs
The analog inputs are parameterized as voltage input 0...10 V at delivery. Depending on the connected
sensor, these can be parameterised via the following object:

Explanation
42 = 0…10 V (Default)
52 = 0…20 mA
51 = 4…20 mA
