Data structure
Output data of SETTOT
Byte 1
Control variable 1
Input data of TOTAL
Byte 1 Byte 2
Measured value: floating point number (IEEE 754)
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 1, 2 and 3
Data structure
Output data of SETTOT and MODETOT
Byte 1
Control variable 1: SETTOT
Input data of TOTAL
Byte 1 Byte 2
Measured value: floating point number (IEEE 754)
AO module (Analog Output)
Transmit a compensation value from the PROFIBUS master (Class 1) to the measuring
device.
A compensation value, along with 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
Byte 3 Byte 4
Totalizer configuration
Balancing
Balance the positive flow
Balance the negative flow
Stop totalizing
Factory setting: Value MODETOT (meaning)
0 (balancing)
