 In this post, we will learn the features of SCADA which are a must in an IoT system. You are working on an industrial automation project and you will surely require a SCADA for that. Many times, we get confused as to what is the right SCADA that needs to be chosen for an application. Because there are many factors involved and ignoring even any one of them will surely cause a hurdle in the performance. You have set your machine mechanically and electrically; but if you have chosen the wrong SCADA for the same, then the design is of no use. So, it is important to select the right SCADA for the application, and for that, it is necessary to understand the various criteria involved in it. Features of Scada in IoT System One thing to note is that in this time of the fourth industrial revolution, there are some general features of SCADA that must be considered when you are choosing the right system. It is wrong that if you are provided with all the basic features, then you have selected...

Because there are many factors involved and ignoring even any one of them will surely cause a hurdle in the performance. How to Select a SCADA? You have set your machine mechanically and electrically; but if you have chosen the wrong SCADA for the same, then the design is of no use. So, it is important to select the right SCADA for the application, and for that, it is necessary to understand the various criteria involved in it. Let us have a look at the factors involved in selecting a SCADA. Number of Tags SCADA pricing is based on the number of tags that you will use in your control system. If you have a rough idea of how much tags will be consumed base...

 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...

 In this article, we will learn the concept of 21CFR in SCADA and HMI automation systems. SCADA systems are designed to control and view the operation of a machine or plant in a controlled and efficient manner. As more and more industries are adopting SCADA in their automation integration, some industries are such which require strict adherence to standards and norms for running a system. What is 21 CFR in SCADA? Majorly, they are food and pharmaceuticals. In every country, the FDA (Food & Drug Administration) regulatory board generates this compliance standard for a system to run. Without this compliance, a system cannot be passed to operate. This compliance is called 21 CFR Part Compliance. CFR stands for Code of Federal Regulations. Almost all the SCADA systems have this facility of 21 CFR inbuilt in them fully or partially. Partially means some coding needs to be done by the programmer to achieve the remaining points. 21 CFR System A proper 21 CFR system ensures that the ma...

At this post i will give some basic instructions which are from my personal experience in order to give you a guide for how troubleshooting in automation systems (PLC/DCS) is : Automation systems troubleshooting has in general the same tactic in order to find the solution of system’s fault. Nevertheless, depends the complexity and the size of application and the specific automation system, the troubleshooting steps would be a little different or more complicated. The best knowledge is obtained through practice and actual troubleshooting conditions. Practice again and again is the solution in my opinion. Any supplement and comments are welcome!! How to Troubleshoot a PLC System  Before we proceed, we agree that modern automation systems have PLCs for controlling the application. If we have a small application then the system possibly has a microPLC (or nanoPLC) or another type of compact controller (many times this depends of the application). I said modern automation systems becaus...

 Industrial Control Systems Different Types of Industrial Control Systems are Distributed Control System (DCS), Remote terminal unit (RTU) and Programmable logic controller (PLC). Distributed Control System (DCS) Plant distributed control system (DCS) – While the term DCS applies in general to any system in which controllers are distributed rather than centralized, in the power generation and petrochemical process industries it has come to refer to a specific type of control system able to execute complex analog process control algorithms at high speed, as well as provide routine monitoring, reporting and data logging functions. Figure : Simple example of distributed control systems In most applications, the input and output modules of the system are distributed throughout the facility, but the control processors themselves are centrally located in proximity to the control room. These systems typically use proprietary hardware, software and communication protocols, requiring that b...

 The recommended controller for SCADA systems is the programmable logic controller (PLC). PLCs are general-purpose microprocessor based controllers that provide logic, timing, counting, and analog control with network communications capability. Components of PLC A PLC consists of the required quantities of the following types of modules or cards, mounted on a common physical support and electrical interconnection structure known as a rack. A typical PLC rack configuration is shown in below figure. (1) Power supply : The power supply converts facility electrical distribution voltage, such as 230 VAC, 120 VAC or 125 VDC to signal level voltage used by the plc processor and other modules. (2) Processor : The processor module contains the microprocessor that performs control functions and computations, as well as the memory required to store the program. (3) Input/Output (I/O) : These modules provide the means of connecting the processor to the field devices. Examples of these modules ...

 Three levels of SCADA system architecture are recommended to support Industrial facilities. These vary in configuration to correspond to the size, criticality, and amount of mechanical and electrical equipment installed in the facility as noted. NOTE : The below shown figures are only example configurations which are used in previous decades. Here shown only for reference. Modern configurations are quite easy and simplified. SCADA and PLC Configuration Small PLC SCADA System The small system is recommended to support a remote data and/or telephone switch site. Such a facility would generally include a single service transformer and a single standby diesel generator. Some equipment inside would consist of a small rectifier for a 24 VDC bus, telemetry systems, PLC, HMI, cooling units Systems for these facilities may not achieve the reliability/availability criteria specified for larger facilities. The level of SCADA system redundancy should reflect the mechanical/electrical system r...

 This is a PLC Program to start a Belt Conveyor and also make it selectable from where you want to start a conveyor from Local or Remote. Design SCADA graphics also. By using PLC and SCADA, prepare a PLC program to start a belt conveyor. Also make it selectable from where you want to start Local or Remote. All the interlocks must be included in the program and also design a SCADA graphics.  Conveyor Ladder Logic Problem Solution: To make a complete logic first, we have prepared a control as well as power diagram of the starter. Then we define the inputs and outputs. We have done the wiring from PLC to Starter and Feedback from Field to PLC. For the Program, first check all signals from the fields are healthy. Then we have prepared a local start/stop logic. For healthy running, check all the interlocks from the fields are ok. If there will be any fault, then we have activated Error signal. After preparing a PLC program we heave design a SCADA in which all the signals are clearl...
