Function description
TOTALIZER → TOTALIZER (1 to 3) → OPERATION
! Note!
The function descriptions below apply to totalizers 1 to 3; the totalizers are independently configurable.

Totalizer 2
Totalizer 3
Data type:

Displays the total for the totalizer's measured variable aggregated since measuring
began. The value can be positive or negative, depending on the setting selected in
the function “TOTALIZER MODE” (3002), and the direction of flow.
Display: max. 7-digit floating-point number, including sign and unit
(e.g. 15467.04 m
3
; −4925.631 kg)
! Note!
• The effect of the setting in the “TOTALIZER MODE” function (see Page 55) is
as follows:
– If the setting is “BALANCE”, the totalizer balances flow in the positive and
negative directions.
– If the setting is “FORWARD”, the totalizer registers only flow in the positive
direction.
– If the setting is “REVERSE”, the totalizer registers only flow in the negative
direction.
• The totalizer's response to faults is defined in the “FAILSAFE ALL
TOTALIZERS” function (3801), (see Page 57).
OVERFLOW
MODBUS register:

Totalizer 2
Totalizer 3

Float

Displays the total for the totalizer's overflow aggregated since measuring began.
Total flow quantity is represented by a floating-point number consisting of max. 7
digits. You can use this function to view higher numerical values (>9,999,999) as
overflows. The effective quantity is thus the total of OVERFLOW plus the value
returned by the SUM function.
Example:
Reading for 2 overflows: 2 E7 kg (= 20,000,000 kg).
The value displayed in the function SUM = 196,845.7 kg
Effective total quantity = 20,196,845.7 kg
Display: integer with exponent, including sign and unit,
e.g. 2E7 kg
