8.5 Read totalizer and inventory values

Display To read a totalizer or inventory value from the display, it must be configured as a display variable.
ProLink III View the desired variable on the main screen under Process Variables.
Service Tools → Variables → Totalizer Control
Field Communicator
Totalizers keep track of the total amount of mass or volume measured by the transmitter since the last
totalizer reset. Inventories keep track of the total amount of mass or volume measured by the transmitter
since the last inventory reset.
Tip
You can use the inventories to keep a running total of mass or volume across multiple totalizer resets.

8.6 Start and stop totalizers and inventories

When you start a totalizer, it tracks process measurement. In a typical application, its value increases with
flow. When you stop a totalizer, it stops tracking process measurement and its value does not change with
flow. Inventories are started and stopped automatically, when totalizers are started and stopped.
Important
Totalizers and inventories are started or stopped as a group. When you start any totalizer, all other totalizers
and all inventories are started simultaneously. When you stop any totalizer, all other totalizers and all
inventories are stopped simultaneously. You cannot start or stop inventories directly.
8.6.1 Start and stop totalizers and inventories using the display
Prerequisites
• The Totalizer Start/Stop display function must be enabled.
• At least one totalizer must be configured as a display variable.
Procedure
• To start all totalizers and inventories using the display:
Note
If the PLC is connected and communicating, the start/stop and reset totalizers commands might be
overriding any totalizer commands from the local display or from ProLink III.
a) Scroll until the word TOTAL appears in the lower left corner of the display.
Important
Because all totalizers are started or stopped together, it does not matter which total you use.
