SETTOT function
For a description of the SETTOT function, refer to SETOT_TOTAL module →  108
MODETOT function
In the MODETOT function, the totalizer can be configured via control variables.
The following settings are possible:
• 0 = Balance (factory setting), calculates the positive and negative flow portions
• 1 = calculates the positive flow portions
• 2 = calculates the negative flow portions
• 3 = Totalizing is stopped
!
Note!
For the calculation of the positive and negative flow portions (control variable 0) or the
negative flow portions only (control variable 2) to be carried out correctly, the option
BIDIRECTIONAL must be active in the MEASURING MODE (6601) function.
TOTAL function
For a description of the TOTAL function, refer to TOTAL module →  107
Data structure of the SETTOT_MODETOT_TOTAL module combination
Example of using the SETTOT_MODETOT_TOTAL module
If the SETTOT function is set to 1 (= reset the totalizer), the value for the aggregated total is
reset to 0.
If the aggregated total of the totalizer should constantly retain the value 0, the MODETOT
function must first be set to 3 (= totalizing is stopped) and then the SETTOT function must
be set to 1 (= reset the totalizer).
DISPLAY_VALUE module
Any value (IEEE 754 floating point number), including status, can be cyclically transmitted
via the PROFIBUS master (Class 1) directly to the local display using the DISPLAY_VALUE
module (slot 6). Display value assignment to the main line, additional line or information
line can be configured via the local display itself or an operating program (e.g. FieldCare).
Output data
Status
The measuring device interprets the status in accordance with PROFIBUS Profile
Specification Version 3.0. The statuses OK, BAD and UNCERTAIN are indicated on the local
display by a corresponding symbol. →  69
