8.4 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 II ProLink > Totalizer Control
Field Communicator Service Tools > Variables > Totalizer Control
Overview
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.
8.5 Start and stop totalizers and inventories
Display See Section 8.5.1.
ProLink II ProLink > Totalizer Control > Start
ProLink > Totalizer Control > Stop
Field Communicator Service Tools > Variables > Totalizer Control > All Totalizers > Start Totalizers
Service Tools > Variables > Totalizer Control > All Totalizers > Stop Totalizers
Overview
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.
