SCADA stands for supervisory control and data acquisition. It is a type of software application program for process control. SCADA is a central control system which consist of controllers network interfaces, input/output, communication equipments and software. SCADA systems are used to monitor and control the equipments in the industrial process which include manufacturing, production, development and fabrication.
(1) Distributed control systems (DCS) are digital control systems that connect field instruments like sensors to computers and human-machine interfaces. They are used in industrial processes to monitor and control distributed equipment. (2) SCADA systems focus on supervisory control and data acquisition from a central location rather than full control. They are software packages that interface with hardware controllers. (3) Historically, DCS controlled processes locally while SCADA provided higher-level control, but modern networks have blurred the distinction between the two terms which are now often used interchangeably.
SCADA systems are used to monitor and control geographically dispersed industrial processes. A SCADA system consists of field devices like PLCs and RTUs that connect to sensors and convert signals to digital data. This data is communicated to a control center via telemetry where it is processed by a data acquisition server and presented to human operators through an HMI. The system allows operators to monitor and control the industrial process. SCADA has evolved from early monolithic centralized systems to modern distributed and networked systems that utilize open standards and protocols to distribute functionality across a wide area network. SCADA is commonly used in applications like power generation, water treatment, oil and gas pipelines, and more.

Comparative analysis of traditional scada systems and io t implemented scadaIJARIIT
SCADA system stands as an abbreviation of Supervisory Control and Data Acquisition. It focuses on the supervisory
level and is not a full control system. It is a computer system which gathers and analyses real time data. They are useful in
monitoring and controlling a plant or industrial equipment like telecommunications, water, waste control, energy, oil-gas
refining, and transportation. It gathers information about a mishap, transfers it back to a central site and alerts the home station
about the mishap, carries out necessary analysis and control, like determining if the mishap occurred is critical, and display the
information in a logical and organized fashion. They can be relatively as simple as a system which monitors environmental
conditions of a small office building, or as complex as a system that monitors all the activity in a nuclear power plant.
IOT acts as a complementary setup to SCADA. SCADA system generates information which acts as one of the data sources for
IOT. While the focus of SCADA on monitoring and control, the focus of IOT is firmly on analyzing machine data to improve
productivity.
SCADA systems are control system architectures used in industrial and infrastructural processes that use networked communications and GUIs for high-level process supervision and management. They implement distributed databases containing tags or points throughout the plant that represent input or output values monitored and controlled by the centralized SCADA system. Programmable logic controllers and remote terminal units connect to sensors and actuators in the process and are networked to the supervisory computer system. SCADA systems have evolved from early monolithic systems using minicomputers to modern distributed and networked systems that can leverage cloud computing and internet of things technologies. Security of SCADA systems is important as compromise could impact dependent infrastructure, though older systems were not designed with modern cybersecurity challenges
[White paper] detecting problems in industrial networks though continuous mon...TI Safe
Automation networks offer a range of real-time applications and data, making necessary the continuous monitoring of the quality of services. The parameters of QoS (Quality of Service) seek to address priorities, bandwidth allocation and network latency control. There are several QoS parameters to characterize a computer network, and that can be used for monitoring purposes.
Each SCADA network, in a healthy state, presents a specific QoS which rarely changes given the repetitive process of the IACS operations. The continuous monitoring of QoS parameters of an automation network may anticipate problems such as malware contamination and equipment failures like switches and routers. It is very important to be aware of these changes in behavior in order to receive alerts and promptly handle them, avoiding incidents that could compromise the operation of the network and be financially or environmentally costly.
In addition to the monitoring of network traffic, it is also necessary to monitor resource consumption of critical servers, such as the processing (CPU), memory, storage capacity and hard disk failures, among others.
This work aims to establish a method by which SCADA security professionals can differentiate and qualify any problems that may be occurring through continuous monitoring of the automation network performance parameters giving a more behavioral approach than current signature-based ones.
We presented a series of tests conducted in our laboratories in order to measure the performance of a simulated automation network parameters using a small SCADA network sandbox. First we measured the normal operating parameters of the network and reap its main graphics obtained with the proper tools. In a second step we practiced several attacks against the simulated automation network. During all attacks we collected the operating parameters of the network and its main graphics.
At the conclusion of the work we compared the graphs of the network in healthy state with the graphs of the network with the security incidents described above. We detailed how the network parameters were affected by each kind of incident and built a table showing the way the main parameters of an automation network were affected by the attacks

Abstract
SCADA stands for Supervisory Control and Data Acquisition. As the
name indicates, it is not a full control system, but rather focuses on the
supervisory level. It is a computer system for gathering and analyzing real
time data. SCADA systems are used to monitor and control a plant or
equipment in industries such as telecommunications, water and waste
control, energy, oil and gas refining and transportation. A SCADA system
gathers information, such as where a leak on a pipeline has occurred,
transfers the information back to a central site, alerting the home station that
the leak has occurred, carrying out necessary analysis and control, such as
determining if the leak is critical, and displaying the information in a logical
and organized fashion. SCADA systems can be relatively simple, such as
one that monitors environmental conditions of a small office building, or
incredibly complex, such as a system that monitors all the activity in a
nuclear power plant or the activity of a municipal water system.
This paper describes the SCADA systems in terms of their
architecture, their interface to the process hardware, the functionality and the
application development facilities they provide.

Introduction
What is SCADA?
SCADA stands for Supervisory Control And Data Acquisition. As the
name indicates, it is not a full control system, but rather focuses on the
supervisory level. It is a software package that is positioned on top of
hardware to which it is interfaced, in general via Programmable Logic
Controllers (PLCs), or other commercial hardware modules. Systems similar
to SCADA systems are routinely seen in factories, treatment plants etc.
These are often referred to as Distributed Control Systems (DCS). They
have similar functions to SCADA systems, but the field data gathering or
control units are usually located within a more confined area.
Communications may be via a local area network (LAN), and will normally
be reliable and high speed. Basically, SCADA is a computer system for
gathering and analyzing real time data.
What is data acquisition?
Data acquisition is the process of retrieving control information from
the equipment which is out of order or may lead to some problem or when
decisions are need to be taken according to the situation in the equipment.
So this acquisition is done by continuous monitoring of the equipment to
which it is employed. The data accessed are then forwarded onto a telemetry
system ready for transfer to the different sites. They can be analog and
digital information gathered by sensors, such as flow meter, ammeter, etc. It
can also be data to control equipment such as actuators, relays, valves,
motors, etc.
5. Studymafia.org
So why or where would you use SCADA?
SCADA can be used to monitor and control plant or equipment. The
control may be automatic, or initiated by operator commands. The data
acquisition is accomplished firstly by the RTU's (remote Terminal Units)
scanning the field inputs connected to the RTU ( RTU's may also be called a
PLC - programmable logic controller). This is usually at a fast rate. The
central host will scan the RTU's (usually at a slower rate.) The data is
processed to detect alarm conditions, and if an alarm is present, it will be
displayed on special alarm lists. Data can be of three main types. Analogue
data (i.e. real numbers) will be trended (i.e. placed in graphs). Digital data
(on/off) may have alarms attached to one state or the other. Pulse data (e.g.
counting revolutions of a meter) is normally accumulated or counted.
These systems are used not only in industrial processes. For example,
Manufacturing, steel making, power generation both in conventional,
nuclear and its distribution, chemistry, but also in some experimental
facilities such as laboratories research, testing and evaluation centers,
nuclear fusion. The size of such plants can range from as few as 10 to
several 10 thousands input/output (I/O) channels. However, SCADA
systems evolve rapidly and are now penetrating the market of plants with a
number of I/O channels of several 100K.
The primary interface to the operator is a graphical display (mimic)
usually via a PC Screen which shows a representation of the plant or
equipment in graphical form. Live data is shown as graphical shapes
(foreground) over a static background. As the data changes in the field, the
foreground is updated. E.g. a valve may be shown as open or closed. Analog
data can be shown either as a number, or graphically. The system may have
6. Studymafia.org
many such displays, and the operator can select from the relevant ones at
any time.
SCADA systems were first used in the 1960s.SCADA systems have
made substantial progress over the recent years in terms of functionality,
scalability, performance and openness such that they are an alternative to in
house development even for very demanding and complex control systems
as those of physics experiments. SCADA systems used to run on DOS, VMS
and UNIX; in recent years all SCADA vendors have moved to NT and some
also to Linux.
Architecture:
In this section we are going to details which describe the common
architecture required for the SCADA products.
Hardware Architecture
The basic hardware of the SCADA system is distinguished into two
basic layers: the "client layer" which caters for the man machine interaction
and the "data server layer" which handles most of the process data control
activities. The data servers communicate with devices in the field through
process controllers. Process controllers, e.g. PLC’s, are connected to the data
servers either directly or via networks or fieldbuses that are proprietary (e.g.
Siemens H1), or non-proprietary (e.g. Profibus). Data servers are connected
to each other and to client stations via an Ethernet LAN. Fig.1. shows typical
hardware architecture.
7. Studymafia.org
Figure 1: Typical Hardware Architecture
Software Architecture
The SCADA products are multi-tasking and are based upon a real-
time database (RTDB) located in one or more servers. Servers are
responsible for data acquisition and handling like polling controllers, alarm
checking, calculations, logging and archiving) on a set of parameters,
typically to which those are connected.
However, it is possible to have dedicated servers for particular tasks,
e.g. historian, datalogger, alarm handler. Fig. 2 shows a SCADA architecture
that is generic for the product.
8. Studymafia.org
Figure 2: Generic Software Architecture
Communication:
Internal Communication:
Server-client and server-server communication is in general on a
publish-subscribe and event-driven basis and uses a TCP/IP protocol, i.e., a
client application subscribes to a parameter which is owned by a particular
server application and only changes to that parameter are then
communicated to the client application.
Access to Devices:
The data servers poll the controllers at a user defined polling rate. The
polling rate may be different for different parameters. The controllers pass
the requested parameters to the data servers. Time stamping of the process
9. Studymafia.org
parameters is typically performed in the controllers and this time-stamp is
taken over by the data server. If the controller and communication protocol
used support unsolicited data transfer then the products will support this too.
The products provide communication drivers for most of the common
PLCs and widely used field-buses, e.g., Modbus. Of the three fieldbuses that
are recommended are, both Profibus and Worldfip are supported but
CANbus often not. Some of the drivers are based on third party products
(e.g., Applicom cards) and therefore have additional cost associated with
them. VME on the other hand is generally not supported.
A single data server can support multiple communications protocols;
it can generally support as many such protocols as it has slots for interface
cards. The effort required to develop new drivers is typically in the range of
2-6 weeks depending on the complexity and similarity with existing drivers,
and a driver development toolkit is provided for this.
Interfacing
Application Interfaces / Openness
The provision of OPC client functionality for SCADA to access
devices in an open and standard manner is developing. There still seems to
be a lack of devices/controllers, which provide OPC server software, but this
improves rapidly as most of the producers of controllers are actively
involved in the development of this standard.
The products also provide
an Open Data Base Connectivity (ODBC) interface to the data in the
archive/logs, but not to the configuration database,
an ASCII import/export facility for configuration data,
10. Studymafia.org
a library of APIs supporting C, C++, and Visual Basic (VB) to access
data in the RTDB, logs and archive. The API often does not provide
access to the product's internal features such as alarm handling,
reporting, trending, etc.
The PC products provide support for the Microsoft standards such as
Dynamic Data Exchange (DDE) which allows e.g. to visualize data
dynamically in an EXCEL spreadsheet, Dynamic Link Library (DLL) and
Object Linking and Embedding (OLE).
Database
The configuration data are stored in a database that is logically
centralized but physically distributed and that is generally of a proprietary
format. For performance reasons, the RTDB resides in the memory of the
servers and is also of proprietary format. The archive and logging format is
usually also proprietary for performance reasons, but some products do
support logging to a Relational Data Base Management System (RDBMS) at
a slower rate either directly or via an ODBC interface.
Scalability
Scalability is understood as the possibility to extend the SCADA
based control system by adding more process variables, more specialized
servers (e.g. for alarm handling) or more clients. The products achieve
scalability by having multiple data servers connected to multiple controllers.
Each data server has its own configuration database and RTDB and is
11. Studymafia.org
responsible for the handling of a sub-set of the process variables
(acquisition, alarm handling, archiving).
Functionality:
Access Control
Users are allocated to groups, which have defined read/write access
privileges to the process parameters in the system and often also to specific
product functionality.
MMI
The products support multiple screens, which can contain
combinations of synoptic diagrams and text. They also support the concept
of a "generic" graphical object with links to process variables. These objects
can be "dragged and dropped" from a library and included into a synoptic
diagram. Most of the SCADA products that were evaluated decompose the
process in "atomic" parameters (e.g. a power supply current, its maximum
value, its on/off status, etc.) to which a Tag-name is associated. The Tag-
names used to link graphical objects to devices can be edited as required.
The products include a library of standard graphical symbols, many of which
would however not be applicable to the type of applications encountered in
the experimental physics community. Standard windows editing facilities are
provided: zooming, re-sizing, scrolling... On-line configuration and
customization of the MMI is possible for users with the appropriate
privileges. Links can be created between display pages to navigate from one
view to another.
Trending
12. Studymafia.org
The products all provide trending facilities and one can summarize the
common capabilities as follows:
the parameters to be trended in a specific chart can be predefined or
defined on-line
a chart may contain more than 8 trended parameters or pens and an
unlimited number of charts can be displayed (restricted only by the
readability)
real-time and historical trending are possible, although generally not
in the same chart
historical trending is possible for any archived parameter
zooming and scrolling functions are provided
parameter values at the cursor position can be displayed
The trending feature is either provided as a separate module or as a
graphical object (ActiveX), which can then be embedded into a synoptic
display. XY and other statistical analysis plots are generally not provided.
Alarm Handling
Alarm handling is based on limit and status checking and performed
in the data servers. More complicated expressions (using arithmetic or
logical expressions) can be developed by creating derived parameters on
which status or limit checking is then performed. The alarms are logically
handled centrally, i.e., the information only exists in one place and all users
see the same status (e.g., the acknowledgement), and multiple alarm priority
levels (in general many more than 3 such levels) are supported.
13. Studymafia.org
It is generally possible to group alarms and to handle these as an
entity (typically filtering on group or acknowledgement of all alarms in a
group). Furthermore, it is possible to suppress alarms either individually or
as a complete group. The filtering of alarms seen on the alarm page or when
viewing the alarm log is also possible at least on priority, time and group.
However, relationships between alarms cannot generally be defined in a
straightforward manner. E-mails can be generated or predefined actions
automatically executed in response to alarm conditions.
Logging/Archiving
The terms logging and archiving are often used to describe the same
facility. However, logging can be thought of as medium-term storage of data
on disk, whereas archiving is long-term storage of data either on disk or on
another permanent storage medium. Logging is typically performed on a
cyclic basis, i.e., once a certain file size, time period or number of points is
reached the data is overwritten. Logging of data can be performed at a set
frequency, or only initiated if the value changes or when a specific
predefined event occurs. Logged data can be transferred to an archive once
the log is full. The logged data is time-stamped and can be filtered when
viewed by a user. The logging of user actions is in general performed
together with either a user ID or station ID. There is often also a VCR
facility to play back archived data.
Report Generation
One can produce reports using SQL type queries to the archive,
RTDB or logs. Although it is sometimes possible to embed EXCEL charts in
the report, a "cut and paste" capability is in general not provided. Facilities
exist to be able to automatically generate, print and archive reports.
14. Studymafia.org
Automation
The majority of the products allow actions to be automatically
triggered by events. A scripting language provided by the SCADA products
allows these actions to be defined. In general, one can load a particular
display, send an Email, run a user defined application or script and write to
the RTDB.
The concept of recipes is supported, whereby a particular system
configuration can be saved to a file and then re-loaded at a later date.
Sequencing is also supported whereby, as the name indicates, it is possible
to execute a more complex sequence of actions on one or more devices.
Sequences may also react to external events. Some of the products do
support an expert system but none has the concept of a Finite State Machine
(FSM).
Evolution:
SCADA vendors release one major version and one to two additional minor
versions once per year. These products evolve thus very rapidly so as to take
advantage of new market opportunities, to meet new requirements of their
customers and to take advantage of new technologies.
As was already mentioned, most of the SCADA products that were
evaluated decompose the process in "atomic" parameters to which a Tag-
name is associated. This is impractical in the case of very large processes
when very large sets of Tags need to be configured. As the industrial
applications are increasing in size, new SCADA versions are now being
designed to handle devices and even entire systems as full entities (classes)
15. Studymafia.org
that encapsulate all their specific attributes and functionality. In addition,
they will also support multi-team development.
As far as new technologies are concerned, the SCADA products are now
adopting:
Web technology, ActiveX, Java, etc.
OPC as a means for communicating internally between the client and
server modules. It should thus be possible to connect OPC compliant
third party modules to that SCADA product.
Potential benefits of SCADA:
The benefits one can expect from adopting a SCADA system for the
control of experimental physics facilities can be summarized as follows:
A rich functionality and extensive development facilities. The amount
of effort invested in SCADA product amounts to 50 to 100 p-years!
The amount of specific development that needs to be performed by
the end-user is limited, especially with suitable engineering.
Reliability and robustness. These systems are used for mission critical
industrial processes where reliability and performance are paramount.
In addition, specific development is performed within a well-
established framework that enhances reliability and robustness.
Technical support and maintenance by the vendor.
For large collaborations, using a SCADA system for their controls
ensures a common framework not only for the development of the specific
applications but also for operating the detectors. Operators experience the
16. Studymafia.org
same "look and feel" whatever part of the experiment they control. However,
this aspect also depends to a significant extent on proper engineering.
