How to configure the Totalizer Block
The Totalizer function block takes the input data from the Transducer block, selected by channel
number, and integrates over the time. This block is normally used to totalize flow, giving total mass
or volume over a certain time, or totalize power, giving the total energy.
The Totalizer Function Block integrates a variable (e.g. flow rate or power) in function of the time to
the corresponding quantity (e.g., volume, mass or distance). The rate unit of the Totalizer is
providing by the transducer block. Internally, the time units are converted in rate units per second.
Each rate, multiplied by the block execution time, gives the mass, volume or energy increment per
block execution.
The TOTAL is the totalized quantity. The engineering unit used in the output is the UNIT_TOT. The
unit of the output must be compatible with the unit of the input provided by the transducer by the
channel. Then, if the input the rate is mass flow (like Kg/s, g/min, ton/h) the unit of the output must
be mass (like kg, g, ton, lb, etc.).
For more details, please, see the Function Blocks Specifications.
To configure the Totalizer Block, please, go to the main menu and select Configuration - Totalizer
Block. In this block, the user can configure the block mode operation, selects the channel, Totalizer
mode and unit for the total:
