Totalizer Block
8-89
8.10 TOTALIZER BLOCK (TOT)
The totalizer block can count an analog input signal by converting the linear analog variable
into a number of discrete pulses that are accumulated as a total count. The totalizer has a
range of 0.0 to 9999999.0. An input threshold value may be configured to avoid the totalization
of extraneous low-level signals. The totalizer function can have an UP or DOWN direction. In
the UP direction, the new count is added to the current total count. In the DOWN direction, the
new count is subtracted from the total count. The calculation is shown below along with a
functional diagram of the block in Figure 8-48. The Totalizer displays used to configure the
block are shown in Figures 8-49 and 8-51.
