10. SCADA/HMI building automation
system advantages
Using SCADA platforms for your building automation
system allows you to get exactly the features and
capabilities you want now and in the future as your
needs grow.
SCADA systems are powerful, robust and flexible.
SCADA is robust Manufacturers, water treatment and
other operations have been relying for decades on
SCADA systems to control their processes.

11. Integratability
 Over the years, users have demanded that SCADA system developers
enable connectivity with the unlike systems and networks with their
plants.
 This openness is highly beneficial for building automation systems with
the many diverse component systems to be integrated.
Flexibility
 SCADA systems are scalable and upgradeable.
Reporting
 Which reports do you want where at what time? Want to see status on
all your systems from any web browser anywhere, even from your
smartphone?
 With SCADA, you can do it. As you can also, if you chose, enable
control over remote connections.

program used for the process
control and gather real time from
remote locations for exercising this

20. Communication and software
 The SCADA consist of Hardware and
Software components.
 The hardware collects and feed data into a
computer with SCADA software installed.
 The data is then processed by the computer
before presenting it in a timely manner.

22. CONTROL/ MONITOR FUNCTION
 A system or the complete site is usually
spread over a long geographical
distance, SCADA is the central
system for control and monitor of such a
site or system.
System Concept of SCADA
SCADA

23.  A Programmable Logic Controller
(PLC) or Remote Terminal Unit
automatically performs the main site
control process.
 The host control functions in most
cases are limited to the capability of
supervisory level or site override.
System Concept of SCADA
SCADA

24. SCADA SUBSYSTEM
 HMI-is the apparatus which presents the
process data to a human operator, and
through this, the human operator
monitors and control the process.
 a supervisory(computer) system,
gathering (acquiring) data on the process
and sending commands(control) to the
process.
System Concept of SCADA
SCADA

25.  RTU-connecting to sensors on the
process, converting sensor signals and
sending digital data to the supervisory
systems.
 PLC-used as field devices because they are
more economical, versatile, flexible, and
configurable than special purpose RTU.
 Communication infrastructure connecting the
supervisory system to the RTU.
System Concept of SCADA

26. System Concept of SCADA

27. System Concept of SCADA

28.  Data Acquisition begins at the RTU or PLC level
and includes meter readings and equipment status
reports that are communicated to SCADA as
required.
 Data is then compiled and formatted in such a way
that a control room operator using the HMI can
make supervisory decisions to adjust or override
normal RTU (PLC) controls.

30. What is RTU?
Remote
Terminal
Unit

31. What is RTU?
An RTU monitors the field digital and analog parameters and
transmits data to the Central Monitoring Station. It contains setup
software to connect data input streams to data output
streams, define communication protocols, and troubleshoot
installation problems.
An RTU may consist of one complex circuit card consisting of
various sections needed to do a custom fitted function or may
consist of many circuit cards including CPU or processing with
communications interface(s), and one or more of the following:
(AI) analog input, (DI) digital input, (DO/CO) digital or control
(relay) output, or (AO) analog output card(s).
SCADA

32. RTU
 a microprocessor-controlled electronic device that
interfaces objects in the physical world to a distributed
control system or SCADA (supervisory control and data
acquisition) system by transmitting telemetry data to a
master system, and by using messages from the master
supervisory system to control connected objects.
 Another term that may be used for RTU is remote
telemetry unit, the common usage term varies with the
application area generally.

33. Two basic types of RTU:
1. Single board RTU
2. Modular RTU
SCADA

34. Single board RTU
which is compact, and contains all I/O on
a single board. The single board RTU
normally has fixed I/O (eg.16 digital inputs, 8
digital outputs, 8 analogue inputs, and say 4
analogue outputs).

35. Modular RTU
which has a separate CPU module, and can
have other modules added, normally by
plugging into a common "backplane" (a bit like a
PC motherboard and plug in peripheral cards) is
designed to be expanded by adding additional
modules.

38.  RTUs differ from programmable logic controllers (PLCs) in that
RTUs are more suitable for wide geographical telemetry.
 RTUs, PLCs and DCS are increasingly beginning to overlap in
responsibilities, and many vendors sell RTUs with PLC-like
features and vice versa.
 In addition, some vendors now supply RTUs with comprehensive
functionality pre-defined, sometimes with PLC extensions and/or
interfaces for configuration.
 Some suppliers of RTUs have created simple graphical user
interfaces GUI to enable customers to configure their RTUs easily.
In some applications data loggers are used in similar applications.

41. FUTURE TRENDS IN SCADA
Julius Jay Sinados

42. FUTURE TRENDS IN SCADA
First generation: "Monolithic“
Second generation: "Distributed“
Third generation: "Networked"

43. First generation: "Monolithic"
 In the first generation, computing was done by mainframe computers.
 Networks did not exist at the time SCADA was developed.
 Thus SCADA systems were independent systems with no
connectivity to other systems. Wide Area Networks were later
designed by RTU vendors to communicate with the RTU.
 The first-generation SCADA system was redundant since a back-up
mainframe system was connected at the bus level and was used in
the event of failure of the primary mainframe system.
FUTURE TRENDS IN SCADA
SCADA

44. Second generation: "Distributed"
The processing was distributed across multiple stations which were
connected through a LAN and they shared information in real time.
Each station was responsible for a particular task thus making the
size and cost of each station less than the one used in First
Generation.
FUTURE TRENDS IN SCADA
SCADA

45. Third generation: "Networked"
Due to the usage of standard protocols and the fact
that many networked SCADA systems are accessible
from the Internet, the systems are potentially vulnerable
to remote attack.
