Deltav System Concepts: Terminology

The document discusses the DeltaV system and its key components. The DeltaV system uses plug-and-play technology and reusable control modules to simplify configuration. It also provides integrated help and documentation. Control strategies are configured using modules that contain algorithms and logic to define process equipment behavior. Modules are centered around a single field device for easy creation, download, and maintenance.

 At least one I/O subsystem per controller that processes information from field

devices
 System Identifier
The System Identifier, shipped in the License Pack, is a connector that plugs into the
parallel printer port or Universal Serial Bus (USB) on the ProfessionalPLUS
workstation. It gives each DeltaV system a unique identification that allows you to
download changes to the system. Install the System Identifier on the
ProfessionalPLUS workstation before you power up your system. DeltaV systems may
be engineered and configured using a Development System Identifier prior to going
online. DeltaV systems used for training or simulation may use a Multi-Node Simulate
System Identifier. Development and Multi-Node Simulate System Identifiers cannot
be used for online, running systems. Only a User System Identifier can be used with
an online system. Refer to the Knowledge Base for information on converting a
system based on a Development or Multi-Node System Identifier to one based on a
User System Identifier.

DeltaV System Concepts


The DeltaV system helps users create process control systems that are easy to set up,
easy to operate, consistent, and secure. To accomplish these goals, the DeltaV system
uses the following:
 Plug-and-play technology for hardware configuration
 A library of reusable control modules to simplify the initial configuration effort
 Integrated, context-sensitive help and online documentation
 Hardware and software approaches to ensure system security and integrity

Terminology
Control strategies in the DeltaV system are configured in modules. A module, which
is the smallest logical control entity in the system, contains algorithms, conditions,
alarms, displays, historical information, and other characteristics that define the
process equipment. Algorithms are the logical steps that define how the module
behaves. The DeltaV system provides control, equipment, and unit modules.
Generally, a control module contains one uniquely tagged control entity, such as a
control loop or motor, with its associated logic. Defining a module around a single
field device and its related control logic makes it easy to create, download, operate,
debug, and take a single module out of service without affecting other modules.
