Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
Measured value: floating point number (IEEE 754) Status
SETTOT_MODETOT_TOTAL module
The module combination consists of the SETTOT, MODETOT and TOTAL functions:
• SETTOT: Control the totalizers via the PROFIBUS master.
• MODETOT: Configure the totalizers via the PROFIBUS master.
• TOTAL: Transmit totalizer value, along with the status, to the PROFIBUS master.
Three Totalizer blocks are available (slot 9 to 11).
Selection: totalizer configuration
MODETOT value Totalizer configuration
0 Balancing
1 Balance the positive flow
2 Balance the negative flow
3 Stop totalizing
Factory setting

AO module (Analog Output)
Transmit a compensation value from the PROFIBUS master (class 1) to the measuring
device.
A compensation value, including the status, is cyclically transmitted from the PROFIBUS
master (class 1) to the measuring device via the AO module. The compensation value is
depicted in the first four bytes in the form of a floating point number as per the IEEE 754
standard. The fifth byte contains standardized status information pertaining to the
compensation value.
Five Analog Output blocks are available (slot 12 to 14, 22 to 23).
