Supervisory Control And Data Acquisition
It is a common process automation system
Functions:
 Gather data from sensors (Local-Remote)
 Transmit
 and display this data at a central site
 Control and monitor the process

5. Why to switch to SCADA
Greater Amman has a population of around 2.1m
people and around 380,000 subscriptions to
LEMA .
Subscriptions within Amman is increasing at
about 5% each year .
The need to monitor and control all the stations,
pumps, wells, and springs from single station.
Control as much stations as we can with low
human factor.
Save water.

18. Programmable Logical controllers
Functions:
Control the operation of the stations
Read the data from field or other RTUs
Send data to the SCADA master
PLC

19. PLC Programming
To program a PLC you need :
PLC
Interface cable
Computer
Programming Software
Smart programmer.

26. The core of SCADA system is the remote access
and control.
Sites are far a part of each other
Distances vary between 500 m to 100 Km.
Signals can’t travel alone
Modems are required.
Communication
Communication

27. Modems
Types of modems:
Dedicated line modems
Wireless modems
GSM modems
Satellite modems
Telephone modems
Communication

28. Protocols
Set of rules and conventions for the
communication.
It is a way for representing the data in the
message.
It is the language that the PLC talks.
SCADA system and the PLC must use the same
protocol.
Examples:
ModBus, Field Bus, Profi bus,TCP/IP, and
industrial Ethernet .

37. Message System
Notify the operator for any new alarms.
Displays any event happen during the operation.
Keeps a short term archive for the events.
Discard specific messages to be removed without
acknowledgment.
SCADA
Software

38. Much similar to message system.
Keeps a long term log for the events (could reach 2 years
or more).
Very helpful for components history within the plant.

Archiving System
SCADA
Software

39. Report system:
Provide printable version of the archives and trends.
Trend system:
Provide an online-offline archive for analogue signals.
Keeps a long term log for the analogue signals.
Very useful for error tracing for the maintenance.

42. Summary
Potable water is very critical issue which encouraged us to
use new technologies such as SCADA.
SCADA system monitors and controls the station in very
easy and human friendly way.
The use SCADA systems reduce the number of operators
and human error factors.
 Several ways can be used for the communications in the
SCADA system with totally same architecture.
Sensors are the eyes of the operator in the site.
