Parameter filtering

Some function blocks have a large number of parameters. To help you quickly access the parameter information you need, the parameters are filtered. The Parameter View window in Control Studio shows the filtering that is currently applied to the parameters. When you want to change the system parameter filtering, use the DeltaV Explorer.

Standard system parameters have been put into filtered subsets to show you the parameters that are likely to be most meaningful to you for different tasks. These categories are not hierarchical or mutually exclusive. The system parameter subsets are:

Common Configurable — the parameters most commonly used during configuration.
Advanced Configurable — the parameters less commonly used during configuration or those used to configure advanced functions.
I/O References — the parameters that reference I/O signals from field devices.
Connectors — the parameters that reference the wired inputs and outputs of a function block or module.
Online Parameters — the parameters used for debugging an algorithm or for operating the process.

You can choose the subset(s) you want to view by clicking the filter buttons corresponding to the subsets you want to display. Turning on all five system parameter subsets ensures that you see all the system parameters associated with the block. Some parameters are in more than one system subset, but they are displayed only once in the parameter list regardless of the subsets you choose to view.

During configuration, you can select or define a grouping of all available parameters that best meets your needs. You do this by assigning parameters to filter groups:

In the Control Studio, Recipe Studio or DeltaV Explorer, open the Properties dialog for the parameter.
Click Filter to assign the parameter to one or more of the user groups.

The user parameter groups are:

Quick Config — a group of parameters often used for the configuration of new modules. This grouping has a default list of parameters, but you can change them according to your needs. The parameters in this list have default values, which can help you configure a module quickly. However, you should examine each default value and modify the values that are not correct for your application.
User-defined 1 — a group of parameters you define for your process
User-defined 2 — a group of parameters you define for your process

You create custom parameter filtering when you configure a custom block. In a custom block, the default action assigns user-defined parameters to the Common Configurable and Online system subsets. However, you can assign the parameters to any system subset and user group you prefer.
