What Is SCADA, and What Can It Do for You?
SCADA is not a specific technology, but a type of supervisory system. Supervisory Control and Data Acquisition (SCADA), is any device that gets data about a system in order to control that system and process data.
A SCADA application has two elements:
1. The process/system/machine you want to monitor and control. This can be a large scale power plant, a water system, communication infrastructures, a network, oil and gas industries, an automated system, a system of traffic lights, or anything else.
2. A network of intelligent devices. Interfaces with the first system through sensors, control outputs, and communications protocols. This network, which is the SCADA system, gives you the ability to measure and control specific elements of the first system.
You can build a SCADA system using several different kinds of technologies and protocols. We will help you evaluate your options and decide what kind of SCADA design is best for your needs.
Where Is SCADA Used?
You can use SCADA to manage any kind of equipment. Typically, systems are used to automate complex industrial processes where human control is impractical. Where there are more control factors, and more fast-moving control factors than human beings can comfortably manage.
Around the world, these kinds of systems find use in a wide variety of applications. Electric power generation, transmission, and distribution is an example.
Electric utilities use SCADA systems to detect current flow and line voltage and to monitor the operation of circuit breakers. Also to take sections of the power grid online or offline. Another is the water and sewage industry.
State and municipalwater utilities use SCADA to monitor and regulate water flow, reservoir levels, pipe pressure and other factors. Buildings, facilities, and environments where specific temperature and humidity considerations are important is another application.
Facility managers use SCADA to control HVAC, refrigeration units, lighting and entry systems. The manufacturing industry uses SCADA systems to manage parts inventories for just-in-time manufacturing, regulate industrial automation and robots, and monitor process and quality control.
Mass Transit authorities use SCADA to regulate electricity to subways, trams, and trolleybuses; to automate traffic signals for rail systems; to track and locate trains and buses, and to control railroad crossing gates. And even your local city traffic department utilizes SCADA to regulate traffic lights, control traffic flow and detect out-of-order signals.
As I'm sure you can imagine, this very short list barely hints at all the potential applications for SCADA systems. It is used in nearly every industry and public infrastructure project - anywhere where automation increases efficiency.
What's more, these examples don't show how deep and complex SCADA data can be. In every industry, managers need to control multiple factors and the interactions between those factors. SCADA systems provide the sensing capabilities and the computational power to track everything that's relevant to your operations.
What's the Value of SCADA to You?
Maybe you work in one of the fields I listed; maybe you don't. But think about your operations and all the parameters that affect your bottom-line results.
Does your equipment need an uninterrupted power supply and/or a controlled temperature and humidity environment? Do you need to know - in real-time - the status of many different components and field devices in a large complex system, such as alarm points? How about the need to measure how changing inputs affect the output of your operations?
What equipment do you need to control, in real-time, from a distance? Where are you lacking accurate, real-time data about key processes that affect your operations? These are questions that proper monitoring and visibility can help answer. The bottom line value depends on the proper application of the right solution to these questions.

Real-Time Monitoring and Process Control Increases Efficiency and Maximizes Profits
Ask yourself as many questions as you can. In time, you'll see where a SCADA system implementation can be applied in your operations. But I'm equally sure you're asking 'So what?' What you really want to know is what kind of real-world results you can expect if you do.
Properly planned systems allow you to access quantitative measurements of important processes, both immediately and over time. They detect and correct problems as soon as they begin. Also, they measure trends over time, discover and eliminate bottlenecks and inefficiencies and control larger and more complex processes with a smaller, less specialized staff.
A properly planned SCADA system gives you the power to fine-tune your knowledge of your systems. You can place sensors and controls at every important point in your critical infrastructure (and as technology improves, you can put sensors in more and more remote locations). Remote terminal units (RTUs) and an HMI (human-machine interface) will be responsible for bringing all the information to you.
As you monitor more things, you have a more detailed view of your operations in real-time. So even for very complex manufacturing processes, large electrical plants, etc., you can have an eagle-eye view of every event while it's happening. And that means you have a knowledge base from which to correct errors and improve efficiency. You can do more, at less cost, providing a direct increase in profits.
What Are the Capabilities of SCADA?
Here are few of the things you can do with the information and control capabilities you get from a SCADA system:
- Access quantitative measurements of important processes, both immediately and over time
- Detect and correct problems as soon as they begin
- Measure trends over time
- Discover and eliminate bottlenecks and inefficiencies
- Control larger and more complex processes with a smaller, less specialized staff.
A SCADA communication system gives you the power to fine-tune your knowledge of your systems. You can place sensors and controls at every critical point in your managed process (and as SCADA technology improves, you can put sensors in more and more places). As you monitor more things, you have a more detailed view of your operations in real-time.
So, even for very complex manufacturing processes, large electrical plants, etc., you can have an eagle-eye view of every event while it's happening. You'll have a knowledge base from which to correct errors and improve efficiency. With SCADA, you can do more, at less cost, providing a direct increase in profits.
Think about your operations and all the parameters that affect your bottom-line results:
- Does the equipment at your remote sites need an uninterrupted power supply and/ or a controlled temperature and humidity environment?
- Do you need to know - in real-time - the status of many different components and devices in a large complex system?
- Do you need to measure how changing inputs affect the output of your operations?
- What gear must you control, in real-time, from a distance?
- Where are you lacking accurate, real-time data about key processes that affect your operations?

39. 10 objects added for moving objects between Scripts. WinTrScadaObject_1– WinTrScadaObject_10. You can bind scripts with these objects. For example you can move and read/write the serial port that opened in script 1 to script 2. Object count looks like limited to 10 but it is unlimited. You can put millions object within one object via ArrayList function. Many advantages can be gained by using it with ActiveX functions. For example the objects that created by script like form and all objects can be placed in Scada System pages.
40. Access of group values of the Plc communication objects within the script allowed. Thus group values can be changed while plc’s communicationg at runtime. For example in a system that contains many energy analyzer we can read instant current, voltage data rapidly for each analyzer and read other values once in a hour. We can read values rapidly when one analyzer selected read others slowly. Thus we can modify tag access speed according selected page.
41. At Modbus RTU/TCP-IP Master modul if the station cannot be read for the first time it may skip next time according to selection. Thus closed stations will not slow the network.
