Function
The input signals of the 8−byte user data of the AIF object are converted into corresponding signal
types. The signals can be used via further function blocks.
Byte 1 and 2
Byte 1 and 2 form the control word for the controller. The bits 3, 8, 9, 10, and 11 of these bytes are
directly transferred into the function block DCTRL where they are linked with further signals. The
other 11 bits can be used to control further function blocks.
Byte 3 and 4
form the signal to AIF−IN.W1.
Byte 5, 6, 7, and 8
This user data can be interpreted as different signal types. According to the requirement this data can
be evaluated as up to two analog signals, 32 digital signals or one angle signal. Mixed forms are also
possible.
