2. Read the following values:
• Index 27: The alarm type
• Index 29: The time that this alarm changed status
• Index 28: The type of status change:
-1 = Alarm posted
- 2 = Alarm cleared
7.8 Using the totalizers and inventories
The totalizers keep track of the total amount of mass or volume measured by the transmitter over a
period of time. The totalizers can be started and stopped, and the totals can be viewed and reset.
The inventories track the same values as the totalizers. Whenever totalizers are started or stopped, all
inventories (including the API volume inventory and enhanced density inventories) are started or
stopped automatically. However, when totalizers are reset, inventories are not reset automatically –
you must reset inventories separately. This allows you to use the inventories to keep running totals
across multiple totalizer resets.
The transmitter can store totalizer and inventory values up to 2
64
. Values larger than this cause the
internal totalizer to go into overflow.
7.8.1 Viewing current totals for totalizers and inventories
You can view current totals for the totalizers and inventories with the display (if your transmitter has a
display), ProLink II, a PROFIBUS host, or PROFIBUS bus parameters.
With the display
You cannot view current totals with the display unless the display has been configured to show them.
See Section 8.9.3.
To view a totalizer or inventory value, refer to Figure 7-2 and:
1. Check for the word
TOTAL in the lower left corner of the LCD panel.
• If Auto Scroll is enabled, wait until the desired value appears on the LCD panel. You can
also
Scroll until the desired value appears.
• If Auto Scroll is not enabled,
Scroll until the desired value appears.
2. Refer to Table 7-5 to identify the process variable and unit of measure.
3. Read the current value from the top line of the display.
