What is SCADA
What is Scada? The ultimate goal of SCADA is the provision of a robust, flexible and cost effective software architecture for a wide variety of computer system analysis tasks. With this in mind, SCADA is not just a hardware vendor but also develops software too. The open source Erlang from the Erlang Solutions Company has been used as a general purpose programming language for system monitoring.
Almost all major multinationals today are investing in enterprise resource planning (ERP), and other related business processes, such as enterprise virtualization and enterprise resource planning (ERP), to reduce costs and increase their operational productivity. These processes not only reduce costs but also improve the organization’s efficiency and effectiveness. Software tools like SCADA allow for the integration of all departments within an organization, resulting in improved efficiency and decreased downtime. Reduced efficiency can cause increased downtime, which can ultimately lead to higher maintenance costs and a decrease of profitability.
Poor communication protocols, inadequate storage media capacity and a lack of central processing and analysis resources were the main causes of the problems that ERP faced in its early days. As a result, there was a lot of communication breakdowns that resulted in delays and failed operations. Poor management of information flow also contributed to an increase in outages. Another problem was the absence of a common core of procedures and tools across all the divisions. The problems encountered during the early days of ERP were mostly because of poor communication protocols, insufficient capacity on storage media and the lack of centralized processing and analysis resources. There were many communication problems that led to delays and failed operations.
Scada’s development tools and methods are designed to guarantee fault-tolerance, security, portability, and reliability of distributed systems. They are capable of handling highly accurate and timely data transmission over long distances. They are capable of supporting multiple logical sources and end-users who can connect to them with remote desktop connections or other transports such as LANs, IPs and Wide Area Networks (WANs). The utility and features of Scada systems have improved with the advancement of new technologies.
Operators should have the ability to input specific diagnostics and alerts using a user-friendly interface into their Scada systems. They should be able determine the root cause of a problem and plan their actions accordingly. Remote access should be possible for operators to manage their servers and remotely apply patches and enhancements. There are advanced troubleshooting tools available in Scada which allow operators to reset counters, set triggers for specific alarms and perform log analysis. With advanced scheduling capabilities, operators can easily organize the work of different departments and assign priority to different tasks. Operators should be able to easily work with the master planner and create work flows for the execution of scheduled tasks.
Modern industries are incorporating remote control software to monitor industrial processes and performance. It enables the users to monitor all parameters of the process from a central location. This software has the advantage that users can access all information from a central location. Industrial processes can be centralized further by installing the radio frequency identification (RFID) tags into the various machines.
There is a lot of misunderstandings about what exactly SCADA is and how it can help organizations. SCADA stands for “supervisory controller and data acquisition”. This is a common misconception. This is a mistake, SCADA is not a technology. SCADA is a method for coordinating and analysing the interaction between people, systems and technology in complex businesses. The following figure depicts the relationship of SCADA to HMI or Human-Machine Interface.
Important Note: You don’t need the latest model of iFIX. You’re simply missing out on the latest capabilities and improved security. For more information on all of the newest features, visit the RIPTEL web site. Next, you will need to understand what a SCADA module does.
SCADA is a method of consolidating and analysing the interaction between human beings, machines, resources, and other resources in complex business situations. To do this, it uses a vast network of interconnecting terminals to gather and transmit the input and output information in real time. In addition to this input and output, SCADA has a distribution system and various software components. SCADA is made up of many smaller but equally important subcomponents. If one of these subcomponents fails, the entire system will fail.
A typical SCADA system consists of at least five main components. The terminals are located in the field and link with the mainframe using Ethernet or Fiber optics. The master station is a computer which is directly connected to the Internet connection to a private network. A router (also known as a switch) connects the Internet to the LAN and to the rest of the system. The central control station is the second main component. They are also known as the supervisor and have the responsibility of maintaining communication between all the SCADA modules.
Each of the four main components mentioned above is capable of supporting different SCADA Functions. Let’s take as an example the HMI. An HMI (Human-Machine Interface) provides the means for an entity to send and receive information from remote sites. The main goal for an HMI is to provide interactive user access to a machine that resides in a remote site, and to maintain efficiency in operations by transmitting instructions to and from the machines in remote sites.
In order to send and receive data from remote sites, the HMI should have at least three main components: an Ethernet port, a device driver, and a communication module, which is a telephone software tool or an application that can be installed on a control system to provide interactive user access to the HMI. Because it allows devices such as printers and network interface cards to communicate with remote sites, the Ethernet port is vital. The device driver allows an IT manager to locate and select physical devices such as computers and computer operating systems to work with on a remote site. The communication module is used to maintain communication between the Ethernet port, the devices in remote sites, and the control relays, and to enforce security and logical restrictions on input and output activities.
Who Uses SCADA?
Who uses SCADA? SCADA is a constellation of system resources, which includes information about the supervisory control and data acquisition processes of computers. These processes enable safe acquisition, access to, analyze, manage and save data. Basically, these systems are used to achieve this goal by enabling computer networks to work. The question now is, “Who uses SCADA?”
One of the many tasks they perform in the large-scale utility industry is to provide communication channels for information transfer from one point or another. They are used to support communication within their facilities as well as for their off-site customers. Communication involves channeling traffic between terminals and switching equipment and is usually accomplished through electrical means such as with the help of fiber optic cables or through radio frequencies.
Large-scale utilities often use their communication infrastructure network (CIT) to provide remote operators with the means to send, receive and configure messages. The operator at the substation site can use radio signals to transmit and configure his message to key components in another location. Another example is the use of powerlines to communicate with key components at other locations. These key components and utility operators can cause delays in certain cases. In order to avoid these delays, maintenance personnel must be deployed to serve as back-up for the operator in case the primary operator fails to respond promptly to an emergency.
Hospitals often have maintenance personnel who provide support for diagnostic procedures, such as neurology, orthotics, and cardiology. These professionals can also perform invasive surgical procedures such as heart surgery. They can access patient information in medical databases and facilitate other data-driven decisions such as expanding the scope of certain surgical procedures. They are also able to provide expert testimony in court due to their specialized knowledge. SCADA was created to assist medical professionals. This technology is often used to protect patients’ lives and prevent unwelcome accidents at the operating table.
Large organizations also use SCADA for decision support. It helps in the analysis, prioritization and correction of problems that affect a large number of different business units. It allows maintenance personnel to make informed decisions concerning pipeline congestion, providing them with the means to increase throughput capacity and reduce system downtime. It also allows organizations to design and implement process improvements to maximize their capital budget.
SCADA has allowed the efficient handling and sharing of many data types through the creation of many sophisticated communication channels. Its development in the field of computer science and allied sciences has led to the integration of these systems in hardware and software that can be used in a multitude of environments. In fact, SCADA has become a very important tool in the enterprise for managing and controlling remote locations.
Modern SCADA Systems
Many industries use modern SCADA systems in their day-to-day operations. In fact, the field of industry where modern systems have an impact is not one isolated one. It has affected every sector of our society, from manufacturing to transportation to financial services. Because every aspect of our lives must be run at maximum capacity, 24 hours per day, this is why it is so important. This requires constant data, information, and interaction throughout all processes.
Although there have been many technologies that tried to overcome this barrier, only modern systems have been accepted and proven to be true industry allies. Modern SCADA systems can interface with remote locations and provide real time data collectors that can communicate over multiple communication networks. Edge-computation devices are also possible, which collect and analyze real time data closer to its source. They can also support MQTT, which is a new protocol that oil and gas companies are using to quickly send critical data back and forward to the control room.
The first step towards fully embracing modern technology is to build a network infrastructure that is capable of supporting distributed control. This requires the creation of a number remote access devices (RAS), and thin clients. These will allow multiple SCADA devices access the same data simultaneously. A typical Thin Client will include a compact modular design consisting of an interface with a main memory, logic and Ethernet cards. The logic part is mostly executed on the main memory. With modern devices such as the Riemenschneider HDL-based Thin Clients, the probability of collision is almost nil, and thus real-time data transfers are instant and hassle-free.
Another essential element in a modern system is an integrated analytics platform. This component combines visual analytics with the SCADA monitor to provide detailed information about the facility’s operational status. It provides real-time analytics for everything from plant status to pipeline operations to welding operations, and even the ability to monitor the performance of the facility’s system. The benefit to the operator is that the analytics system allows them to centrally manage the operations of the entire plant and can alert them to potential problems before they happen. In this day and age, centralized management for anything goes a long way, and integrating digital oilfield monitors into the operational framework of a facility is certainly a step in the right direction.
The modern strategic control system is also dependent on global positioning systems. With Geographic Information Systems (GIS) a user can generate and store geographical data and then use it for a variety of purposes including operational intelligence, engineering purposes and analyzing resource utilization. A GIS-based operational database allows companies to quickly and efficiently analyze large amounts of geographical data and create detailed reports on both an operational and resource optimization level. Fully implemented GIS based strategic control system can certainly improve the efficiency of any operation, and one of the key elements in today’s modern SCADA systems is the ability to rapidly and efficiently analyze GIS based data.
Real-time traffic information is a key component of modern systems. A large number of modern devices come with GPS/RFID technologies that provide real-time traffic information to the device’s operator. These devices can be used for safety and security purposes, as well as to control facilities and monitor traffic. Modern systems use channels to link traffic information to either a human operator, or to central control. These devices can also be used for remote operation by other humans or machines, or just by the facility itself in order to gain more insight into the operation of the facility as a whole.
