Control Builder uses icons to represent control blocks, which can be "wired" together using simple point
and click techniques. Control drawings can be used on-line to monitor control execution and make
changes to control parameters, thereby significantly simplifying control strategy checkout. Control
drawings are also accessible to the operator via detail displays.
Control Builder also supports Hierarchical Building that enables nesting of Control Modules
regardless of their controller assignment and the creation of projected parameters. These are FB
parameters, which are now promoted to the boundary of the control module with a user-defined name.
These parameters are used to make wired connections between Control Modules and/or FBs. It also
provides the configuration engineer with the ability to organize the control configuration in a more
process-oriented way. For example, a user may create one Control Module named "Reactor" and
embed the individual temperature, pressure and agitator Control Modules and the fill sequence. Any
interconnection can be "soft- wired"
between user-defined parameters.
The user can switch the Control
Builder view between the traditional
assignment view (controller oriented
view) and the new containment
view.
Projected parameters can be
defined without immediately
resolving the source parameter.
This supports a "top-down"
implementation. In a top down
design, the overall control strategy
is defined on a high level with minor
detail. Once the overall strategy is
defined, more detail is added to the
underlying Control Modules.
The Control Builder enables the
creation of reusable control strategies, which can be duplicated, with minimal effort through a simple
copy and paste action. To further increase the engineering productivity of Control Builder, it optionally
supports User Templates. With this licensed option, the user can create block templates and/or
Control Module templates. These templates appear under the user library on the library tab. These
user templates can be instantiated and loaded to a control environment. Whenever a change is made
in the template, it will automatically propagate the change through all instances. Propagation of
template defining parameters is unconditional. Non-template defining parameter propagation is
conditional, where the change is propagated if the value of the parameter in the instance is equal to the
old template parameter value.
Control Builder also supports a multi-user control strategy development and debugging environment.
The function provides remote access to engineering databases across any media capable of TCP/IP
and UDP/IP communication. For maximum security, access is password protected. Several users
can create, configure and load control strategies at the same time from different workstations. Multiple
users can have the same chart open, with full write access to the first user who opens a chart.
When multiple users open a chart for monitoring, all users can change controller values based on their
security level.
The Fieldbus Configuration Tools integrates the Controller with Fieldbus devices. Key features
include:
•
Communication through the ControlNet path from the Experion PKS Server
•
Block and Device tag and address setting
•
An easy-to-use graphical environment for creating linkages, loops and a schedule based upon Fieldbus
concepts.
•
Configuration of hardware information, ControlNet network addressing, Linking Device paths, Device
descriptions, and the base directory to store Device Description information.
