Data structure
Input data of Analog Input
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
Measured value: floating point number (IEEE 754) Status
TOTAL module
Transmit a totalizer value from the measuring device to the PROFIBUS master (Class 1).
A selected totalizer value, along with the status, is cyclically transmitted to a PROFIBUS
Master (Class 1) via the TOTAL module. The totalizer 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 totalizer value.
Three Totalizer blocks are available (slot 9 to 11).
Selection: totalizer value
The totalizer value can be specified using the CHANNEL parameter.

SETTOT_TOTAL module
The module combination consists of the SETTOT and TOTAL functions:
• SETTOT: Control 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).
