6.12 SPM configuration with EDDL
For host systems that support Electronic Device Description Language (EDDL), using SPM is made easier
with step-by-step configuration guidance and graphical displays. This section of the manual uses AMS
Device Manager version 10.5 for illustrations, although other EDDL hosts could be used as well.
The SPM Configuration Wizard can be launched by selecting Statistical Process Monitoring from the
Configure > Guided Setup page.
This wizard will take you step-by-step through the parameters needed to configure SPM.
6.13 EDDL trending of mean and standard deviation
Once the SPM has been enabled, the EDDL user interface allows for easy viewing and trending of mean
and standard deviation. To open up the trending screen, select Service Tools > Trends > Statistical
Process Monitoring.
The EDDL Screen will show an online trend of mean and standard deviation, along with the baseline
values, percent change, and detection limits (Figure 8).
Figure 8. EDDL Trend of Mean and Standard Deviation
Note that data shown on the EDDL trends are not stored in a process historian or other database. When
this screen is closed, all past data in the trends plots are lost. See “Trending SPM data in DeltaV” on
page 18 for configuring SPM data to be stored in a historian.
6.14 Trending SPM data in DeltaV
Refer to “Trending statistical values in control system” on page 17 for general information about
accessing the SPM data through the AI function blocks. This section shows a specific example of how
SPM data can be accessed within the DeltaV host system, saved into the process historian, and used to
generate a process alert.
1. In DeltaV Control Studio, add an AI function block.
2. Assign the new block to one of the AI function blocks in the Rosemount 3051S Device.
3. Set the CHANNEL to one of the valid SPM channel values from Table 11 on page 17 (e.g. set the
CHANNEL to 13 for Standard Deviation, as shown in Figure 9).
