It is impossible to keep control and supervision on all industrial activities manually. Some automated tool is required which can control, supervise, collect data, analyses data and generate reports. A unique solution is introduced to meet all this demand is SCADA system.
SCADA stands for supervisory control and data acquisition. It is an industrial control system where a computer system monitoring and controlling a process.
Another term is there, Distributed Control System (DCS). Usually there is a confusion between the concept of these two.
A SCADA system usually refers to a system that coordinates, but does not control processes in real time, but DCS do that. SCADA systems often have Distributed Control System (DCS) components.
Components of SCADA
1. Human Machine Interface (HMI)
It is an interface which presents process data to a human operator, and through this, the human operator monitors and controls the process.

2. Supervisory (computer) system
It gathers data on the process and sending commands (or control) to the process.
3. Remote Terminal Units (RTUs)
It connect to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.
4. Programmable Logic Controller (PLCs)
It is used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.
The has the ability to verify the length of each network cable and identify cable faults and limitations that interfere with network capabilities including split pairs, shorts and open circuits. The can also measure the Signal-to-Noise Ratio, Delay Skew as well as a 1 Gbps Bit-Error-Rate Test to help identify reasons for poor network capability. Network cable testing software. Additional features include network pinging, DHCP, VLAN, link light identification to verify to which ports cables are connected, and the measurement of PoE and more.
5. Communication infrastructure
It provides connectivity to the supervisory system to the Remote Terminal Units.
What are SCADA systems able to do?
As it is known, the SCADA systems are able to measure and monitor different parameters and variables, such as: the level of liquids, the volume of the gases, the volumetric flow rate, the mass of liquids and gases, the pressure, the temperature, the humidity, the viscosity, the position and the moving, etc.
For this, some signals must be acquired based on the appropriate sensors and transducers from different electrical and electronic devices, before to be processed and analyzed by SCADA system. These data can be used for supervision of remote processes.
For this, the data are processed and analyzed to generate reports which will be transmitted to control the processes parameters within certain limits.
The SCADA applications have two basic levels:
- The customer level, which will be performed the human-machine interaction;
- The data server level which will control the entire process.
Thus, the data server sends these data to the customer level via remote equipment such as PLCs (connected to the database server either directly or via a communications network, using various communication protocols).
The developed protocols can be property of a company (e.g. Siemens H1) or of open type (Modbus, Profibus etc.). Database servers can be fully connected to each other and also to the customer stations through Local Area Network (LAN) networks based on Ethernet technology.
The SCADA systems may be relatively simple or very complex, depending of the dimension and complexity of the process monitored. These systems operate in real-time using a database system named Real Time Data Base (RTDB), which can be found on one of servers.

Software Architectures
The SCADA applications are implemented based on the software architecture (Figure 2 below). SCADA software architecture has at least two components:
- The SCADA server application;
- The SCADA client application;
SCADA server and SCADA client
Scada Wonderware Basics Pdf
The SCADA server application is multi-tasking being responsible for storing the SCADA client applications in a database. The SCADA client application receives data via serial port using RS232 and MODBUS RTU protocols.
In many cases the SCADA applications shall be addressed to and remove the users who have not an Internet connection. In this case it is necessary a new software component on a Web server. A Web server is used for generating dynamic Web pages, which are supplied to customers decrease.

The Web SCADA clients can benefit to real-time access (in a manner similar to regular SCADA clients) to the lists of parameters, the lists of events and the list of alarms via a simple browser.
But, the Web SCADA clients do not receive the same level of graphical user interfaces and have the same HMI features as the regular SCADA clients. The regular SCADA clients are accustomed to running specific applications as opposed to The Web SCADA clients who view the Web pages provided by Web SCADA server.
In order to reduce as much difference between the regular SCADA clients and Web SCADA clients some drives, services and virtual instruments are implemented in HMI. Visualization software used for monitoring and control of industrial process is called “software” HMI or “SCADA software”.
HMI as it is called generically, means any switch, interface through which you can control a device. The term “automation” refers to the graphical interfaces implemented through interaction with the mouse and/or the keyboard or by touch.
HMI/SCADA appeared as a terminal dedicated for users from the system implemented with PLC units. A PLC is programmed to automatically control a process. Because the PLC units are distributed in a large system, the data from PLC are stored and then transmitted. HMI/SCADA has the role to gather and combine the data from the PLC using a specific protocol.
HMI software can be connected to a database in order:to fulfill the charts and diagrams in real time:
- To analyze the PLC data;
- To treat the planned maintenance;
- To drill the schemes for a particular sensor or machine;
- To apply the troubleshooting methods of the system.
The basic SCADA protocol is MODBUS, which is designed to send data to the master station even when the master interrogates the RTU station. MODBUS is based on a master-slave architecture known also as client-server architecture.
The protocol is designed to be used by Modicon in own PLCs. Now, it became a standard of communication for the industry and is currently the most widely used to connect all the industrial devices. The protocols contain extensions to operate over Transmission Control Protocol (TCP/IP).
In practice, it is suggested to avoid the security of Internet connection in order to reduce risks of cyber-attacks.
