Main architecture Components

The Master station is an essential machine in

a monitoring system. Despite the redundancy

of components which guarantees reliability

and gives the control system dependable

stability. The backup master station topology

is usually adopted by very critical system or

system that cannot

afford any downtime. Typically, the backup

master station will be located at a far away

geographical

location from the master station, so that the

chances of both places being hit with disaster

at the same time is minimized.

The concept of backup master station is to be

a replication of the master station. Hence the


backup master station should be online all the

time to ensure all data at master station is

synchronized over. This will ensure that

anytime the backup master station needs to

take over control, it will have the latest

status of the system for smooth transition. It

is often the backup master station has the

replicated communication links to remote

RTU/PLCs as well. Both master station and

backup master station can view and control

the SCADA system at the same time, with the

data at backup master station arriving slightly

later than the master station depending on

the physical link between the master station

and backup master station. Generally, the

delay is hardly noticeable.

Communication Protocols

ADACS‐TD® incorporates the following

communication protocols:

• IEC 60870‐5‐101 Master/Slave

• IEC 60870‐5‐104 Master/Slave

• DNP3 Master/Slave

• Modbus RTU/ASCII/TCP

Software Architecture

ADACS‐TD® SCADA package is a combination

of a group of individual applications. They are

being executed according to the project

scenarios and different requirement. These

ADACS‐TD® applications all have to

communicate with a centralized real‐time

database (RTDB) With the centralized RTDB,

ADACS‐TD® has the database synchronizing

over the machines in a master station. The

information and data stored in the database is

also used to notify applications for failover.

Therefore, most of the ADACS_TD processes

has the built‐in redundancy facility. The

machine failover is also supported with the

mechanism and the supervisor program.

Real-Time Supervision & Control

The real-time supervision and control provide

the operators with an ergonomic graphical

interface to quickly access information and

execute orders safely for supervision and

control in real time:


• Configurable shortcuts and navigation

between images are optimized to

facilitate monitoring;

• Different displays are available for field

measurements: Value, gauge, table.

• Audible and visual warnings minimize

reaction time in case of incident

• Detailed representations complete the

topological or geographical extended

representations.

• Sending of order is fast and simple

Historical Database

Historical archiving is performed with

transferring real‐time data changes into a

back‐end Relational Database Server. ADACS‐

TD® provides the historical archiving as a

default package for historical trending and

historical alarm search. The database

supporting package would be installed with

the database purging/housekeeping. Backup

and the restoring of databases would require

customization according to the applied

system.

The supported RDBMS are:

• Oracle

• EDB

• Progress

• Sybase

• DB2

Data Engineering

The Data Engineering provides the offline

configuration database and graphics editor to

verify the add and edit the configuration

before deploy to real-time production.

Data Gateway

Data from SCADA system to provide and

integrate with other application for

businesses operation and report. Data will be

processing on Data Gateway process in

standard data connectivity:

• Data file transfers

• Web service in SOA/XML support

• Gateway Database


Event and Alarm Management

The concept of alarms a basic function in

ADACS‐TD®. There are two types of Alarm

messages: Alarm and Event. Alarm requires

users’ attention and intervention. Event refers

to the action or conditions logged by SCADA

system that does not requires operator’s

immediate notification. The alarm

functionalities of ADACS‐TD®:

• The visualized interface for alarm is

ADACS‐TD® ’s alarm panel. The alarm

message format is can customizable

• format for alarm message display.

• Alarm displayed as the alarm in alarm

panel, as well as color changed or

blinking in a visual object in display

pages.

• Alarm acknowledgement

• Multiple layers of alarm scenarios.

Users could define alarm scenarios with

different level of severities, and

deciding the alarm appearance

accordingly.

• Alarm Grouping: related tags/points

alarms could be categorized into

different group. The grouping would be

displayed on screen and operators

could visualize or pay more attention to

specified group of alarms/points

• Alarm counter

• Log book and Black Box

• Alarm archiving

Graphical User Interface

Graphic Display


ADACS‐TD® graphic display interface built

with a high-performance graphical engine. Its

navigation and response are generally within

fast response. The key features of the

respective drawing tool and graphical display:

• Provides pop‐up dialog for Analog

Input, Digital input, Accumulator Input,

Analog Output, Digital Output and

other configured system entities (e.g.

RTU, PLC, communication ports…etc).

Tracing line for pop‐up is supported.

• Allows an alarm to be drag‐n‐dropped

on display area, the display would be

automatically switched to the page

where the alarm belongs to. This saves

a lot of time on locating where the

alarm point is, especially while it is a

very big project and contains hundreds

of display pages.

• The display page provides cascade or

tile view, page could be splitted

horizontal or vertically for better usage.

• The editor and display support common

graphical format, e.g. jpg, bmp. The

editor also supports importing

AUTOCAD files.

• Function to monitoring all the entities

in the system, including server, HMI

machines, the ADACS_TD

processes/programs running in the

machine, communication links, remote

devices (RTU/PLC)

• Dynamic elements: These are graphic

elements (symbols, text, etc.) for which

a dynamic link has been made to a

database object.

• Static elements, i.e. any graphic

elements that are not dynamic (frames,

background, headings, etc.).

• Additional signals (frames, plates),

which are graphical markings for

certain dynamic objects

• Zooming, panning, decluttering and

drag & drop between windows

Trending


Trending is one of the basic functions in

ADACSTD®. The trending window provides

users choices of different ploting lines, time

interval selection from seconds, minutes to

days, months. The key features included:

• Support both real‐time trending

(retrieve from real‐time database) and

historical trending (retrieve from

historical RDBMS)

• Displaying multiple points/tags in a

single trend window. Up to 6 points

(pens) is allowed to put into a window

• I/O points with trend information could

be dragged into trend window for

display

• Display up to 3 Y‐axis for the value scale

of the points

• Trent Profile setting

Protocol Analyzer

The Protocol Analyzer is a tool used for

analyze signals and data traffic over a

communication channel. Protocol Analyzer is

providing a means of communication using a

standard communication protocol

(networked or point-to-point). Each type of

communication protocol has a different tool

to collect and analyze signals and data.

Gas Measurement Data Retrieval


For billing purpose, SCADA Operator need to

retrieve previous day and previous hour data

from flow computers via RTU to SCADA

server. The RTU has in that case the function

of data concentrator. This data concentrator

RTU is able to poll previous day and previous

hour data from flow computers and keep

them into its internal tables.

Real‐Time Monitoring Web Interface

ADACSTD® provides real‐time HTML graphical

according to points/tags status. The default

graphical including schematic display and

reports to show what points have been set

control inhibited, blocked, manually set value,

.etc.

Well Process Condition

Using algorithm and programming to process

well condition monitoring that were the

source of the design parameters in

conjunction with the real‐time data gives the

operator actionable information on

performance and best operating practices.

Volumes of real‐time data from production

are represented visually so operators can

quickly make fact‐based decisions to follows:

• Optimize performance

• Reduce well downtime

• Remotely math production demand

• Identify poor performing well

• Simplify and consolidating report

• Alert and warn abnormal well condition

Line pack calculation


ADACSTD® provide algorithm ability of a

natural gas pipeline to effectively "store"

small quantities of gas on a short‐term basis

by increasing the operating pressure of the

pipe. Most pipelines use line pack as a

resource to help manage the load fluctuations

on their systems, building up line pack during

periods of decreased demand and drawing it

down during periods of increased demand.
