Fig. 31 schematically illustrates the internal structure of the various Transducer Blocks:
Transducer Block "Flow" TRANSDUCER_FLOW / base index 500:
This block contains all the flow-specific parameters and functions, e.g. calibration functions, sensor
data, etc. Page 89
Transducer Block "Totalizer" TRANSDUCER_TOT / base index 600:
This block contains all the parameters for configuring the totalizer
Page 103
Transducer Block "Display" TRANSDUCER_DISP / base index 700:
This block contains all the parameters for configuring the local display
Page 107
Transducer Block "Diagnosis" TRANSDUCER_DIAG / base index 800:
This block contains all the parameters for system diagnosis, e.g. current system status, etc.

Transducer Block "Service" TRANSDUCER_SERV / base index 900:
This block contains all the service parameters. Access is by entering the special service code.

Caution!
Changing the settings of the service functions can result in a malfunction or device failure. Should
this occur, remove the device and return it to Endress+Hauser.
11.3.1 Block output variables
The Transducer Blocks make the following output variables (process variables) available:
• Transducer Block "Flow"
– Calculated mass flow
– Volume flow
– Corrected volume flow
• Transducer Block "Totalizer"
– Totalizer
• Transducer Block "Diagnosis", "Display" and "Service" do not have any output variables.
The CHANNEL parameter in the Analog Input Function Block is used to assign which process
variable is read in and processed in the downstream Analog Input Function Block:
• Process variable calculated mass flow CHANNEL = 1 (Analog Input Function Block)
• Process variable volume flow CHANNEL = 2 (Analog Input Function Block)
• Process variable corrected volume flow CHANNEL = 3 (Analog Input Function Block)
• Process variable totalizer CHANNEL = 7 (Analog Input Function Block)
