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.
CHANNEL Input variable
32961 Mass flow
33122 Volume flow
33093 Corrected volume flow
901 Target fluid mass flow
793 Carrier mass flow

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).
