 As per IEC 61131-3, there are five PLC programming languages, three are graphical. The other two are textual languages. The three graphical languages are ladder diagram (LD), Function Block Diagram (FBD), Sequential Function Chart (SFC). Two textual languages are Standard Text (ST) and Instruction List (IL). Out of all the above, various languages have different strengths for different tasks. In this article let us discuss Sequential Function Chart (SFC). It is a flow chart-like programming language. The execution of process operations is structured sequentially. It can encapsulate ladder diagram (LD), Function Block Diagram (FBD), Instruction List (IL), and Standard Text (ST) structures to control subroutines. Sequential Function Chart Sequential Function Chart (SFC) can be used to structure the internal organization of a program consisting of sub-programs and are also written in other languages of the standard. It can also be used in its pure form of specifying the logical contr...

 In the first part, we overviewed the PLC’s used for smaller and medium applications. The second part overviews the PLCs used for higher-level applications. M340 – Mid Range PLC The first range of high-end processors in Schneider PLC starts with M340 PLC. It is a very powerful and compact series of PLCs providing high-end efficiency and control solutions in it. This PLC has a program memory of 4 MB, 128 MB of file storage, and executes 7 instructions in a millisecond. The PLC is a modular type which means it requires a rack to configure. The communication part comprises a USB port, 3 Ethernet networks, 1 CAN Open, 1 serial port, 4 ASI, and 37 Modbus buses. The PLC has an embedded web server and file transfer protocols. The main advantage is that the program is stored in a removable SD card. So, whenever the PLC gets corrupt or damaged, just remove the SD card and insert it in the new PLC. The software used for programming is Control Expert. You have all the languages available in i...

Every year means that experts develop new, useful technologies for helping people to deal with different issues. We use their achievements daily to search for information on the Web, contact friends on social media, play games, and so on. One of the most popular examples is artificial intelligence. Its importance is spectacular for different spheres including business, work, education, etc.  So it’s fair to say that technologies are a huge part of a modern individual’s life. Let’s pay more attention to its influence on the educational sphere and find out its main advantages and perspectives for the future.  Powerful and unstoppable technological influence This is a fact: technology causes a very positive influence on students’ experience during campus life. With such many benefits revealed to individuals, they are able to become more engaged in educational programs, more informed about their opportunities, and more powerful in the flow of neverending assignments. Students can ...

 Progress in recent years has contributed to businesses being increasingly reliant on information systems while also making them exposed to external threats and attacks. Every year, new techniques for getting illegal access to databases emerge. Because “who has the information owns the world,” we can see several examples of unfair competition on the market today. Many businesses are attempting to obtain extensive information about their competitors in whatever way possible in order to gain a competitive advantage. Obviously, the issue of maintaining security and data protection is more important than ever for businesses that are battling for market share and confronting external threats. After all, if you do not correctly arrange your work in this direction, it is simple to fail in today’s economic environment. However, there is a good side to information technology progress: new solutions and means of protection develop, allowing for a high level of security of a company’s IT infr...

 This article is divided into two parts. In this article, we will learn different types of Schneider PLCs and an overview of smaller and medium applications in PLC. The second part covers the overview of PLCs used for higher-level applications. Schneider is a very big brand in industrial automation. It has very products and innovative technologies in industrial automation, residential and small business, low voltage products and systems, solar and energy storage, medium voltage distribution and grid automation, etc. If we consider the industrial automation part, it has a very wide range of PLCs. In this post, we will have a look at various ranges of Schneider PLCs. Zelio Schneider PLC This is the most basic version of Schneider PLC. It has a maximum of 20 IO’s. This PLC has buttons on it for operating the in-built HMI display. The LCD display has 4 lines of 18 characters and 1 line of icons. The power supply of this PLC has a variety of ranges like 12V DC, 24V DC, 24V AC, and 230V ...

 Switch Mode Power Supply (SMPS) works by converting high AC voltage into DC power using a transformer, rectifier, MOSFET transistor, as seen on Linear Power Supply (LPS). In essence, it is ideal for providing an additional layer of protection through isolation devices to be included in SMPS. Isolators are devices used to isolate a particular circuit or equipment from a known power source. It serves as a mechanical switch that allows manipulation of both input and output power sources coming in from an open position and isolates both circuits. Switch Mode Power Supply In equipment component failure, isolation serves as a physical barrier to potentially dangerous voltages. By using isolation mechanisms, electric shock and fire hazards are prevented.   An isolated power supply creates a power output that is electrically independent of its input power. When multiple isolated power outputs are used, the output voltage generated is then independent of one another with relative...
