Assignment of the measured variables to the AI module
The AI module can transmit different measured variables to the PROFIBUS master (Class 1).
The measured variables are assigned to the Analog Input function blocks 1 to 4 by means of the local 
display or with the aid of an operating program (e.g. FieldCare) in the CHANNEL function:
COMMUNICATION 
→ BLOCK SELECTION: select an Analog Input function block → 
CHANNEL: select a measured variable
Possible settings
Factory setting:
Example:
You want to cyclically transmit the mass flow to the PROFIBUS master (Class 1) by means of the 
Analog Input function block 1 (module AI, slot 1) and the temperature by means of the Analog Input 
function block 2 (module AI, slot 2).
