Assignment of the measured variables to the AI module
The AI module can transmit different measured variables to the PROFIBUS master system.
The measured variables are assigned to the Analog Input function blocks 1…6 by means of the local
display or with the aid of a class 2 master (operating program) in the “CHANNEL” parameter:
Configuration via the local display:
Function group → BASIC FUNCTION → PROFIBUS DP → FUNCTION BLOCKS → BLOCK
SELECTION → CHANNEL
Configuration via the operating program:
Analog Input function block 1…6 → CHANNEL parameter
Factory setting:
The following settings are possible:
Module Analog Input function
block
Measured variable factory
setting
“CHANNEL” parameter

AI (slot 1) 1 Mass flow 277
AI (slot 2) 2 Volume flow 273
AI (slot 3) 3 Corrected volume flow 398
AI (slot 4) 4 Density 281
AI (slot 5) 5 Reference density 402
AI (slot 6) 6 Temperature 285
