Figure 51: Determining Register Address For Levelmaster Measurement Values (Levels Tab) - ABB LevelMaster 7100 User Manual

Configure trending
The Trend application can be configured to retain the LevelMaster data at a specific location from where they can later be
retrieved. The trend functionality provides the ability to define which data from the LevelMaster will be trended. Each data item
or variable is defined and the app/array/register address storing the variable value is configured.
IMPORTANT NOTES: Details about configuring trending on the flow computer or remote controller vary
depending on the model number and the PCCU32 version used. Click Help for specifics about that version. For
the purpose of illustration, PCCU32 version 7.59 has been used. It is assumed that the Trend application or
functionality has already been activated. If not, and assistance is need, contact technical support.
Advanced users may configure the Trend function to use the Push-to-Read feature to poll on demand.
To configure the Trend application to store the LevelMaster data:
1. Determine the data item or variable that will be trended. For example: level 1 measurement for tank 1.
2. Determine the register (app/array/reg) address where the LevelMaster application is storing the chosen variable
LevelMaster value.
a. On the navigation tree, expand Tank Data.
b. Click the desired tank.
c. Locate the desired variable on the Setup/Status or Levels tabs (Figure 51).
