Engineering Station (Application Workstation AW51B):
Operating system Sun OS runs on AW51B, that is main server for the system and seat on the Nodbus.
All other configuration software likes Historian, ICC, and all advance applications also run on AW51B.
Mainly used for Configuration, System Diagnostic and downloading configuration to all stations configured.
Can be used as Operator station.

Integrated Control Configuartion:
The Integrated Control Configurator database is the backbone of the I/A Series control subsystem and is the primary means by which real-time process
variables are translated to the DCS environment
The software structure of the Control and I/O (CIO) functions revolve around the "COMPOUND:BLOCK.PARAMETER" concept.
A compound as a group of blocks related to a particular Plant Unit, Equipment, Subsystem etc.
A block is a member of a set of predefined algorithms designed to perform mathematical, logical or boolean operations on one or more values.
Both blocks and compounds have PARAMETERS. Parameters include real-time values and may be used for display, trending and other processing requirements.

Human Interface (Operator Work Station):
Operator Work station processor with single or dual CRT, Annunciator Key Board, Trackball and touch screen provide human interface.
The Concept of efficient process control using an operator interface is with the following basic utilities:
Process Graphics
ESD Graphics
Group / Trend Displays
Face Plate Overlays
Alarm Manager

Process Graphics
Process Graphics:
There are four levels of graphics used in Project.
Level – 1: Complex Overview Level – 2: Plant wide Overview Level – 3: Based on PFDs
Level – 4: Based on P&Ids
In addition to above following are other graphics used for the Project.
Group Display: Group of eight Face plate or four Face plate and four treads.
Overlay: Faceplates, Pump START/STOP etc.

Historian & Reports:
The Historian collects, stores, processes, and archives process data from the control system to provide data for trends, Statistical Process Control charts, logs, reports, spreadsheets, and application programs.
The Historian is a tool for collecting, organizing, and storing data for later retrieval. It contains built-in algorithms for reducing data and provides workstation displays to retrieve and display data . Typical data are process analog and/or digital points.
