Features of Scada Which are Must in an IoT System

 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 the correct one. In this post, we will see the characteristics which stand out a SCADA system from the rest of all.

Large Data Support

If you are working in a SCADA system and you do not have enough data tags; then it is of no use. In a large plant, there are so many IOs and their set parameters, that a huge amount of tags are required to bring them into the system.


And once brought, it is important that the SCADA processes the data in a fast and efficient way; without any lag in the system.


So, it is important that the SCADA has provision for taking a large number of tags, as well as processing them quickly. It should not be such slow, that if a PLC tag changes its value, then it is reflected in SCADA after a few seconds. It should also have the facility to import or export tags from other databases.

IoT Connectivity

IoT has many connections and features like OPC, database, IoT, web services, SNMP, MQTT, and BACnet.


The future of automation lies in IoT, and the SCADA selected must be able to communicate with them. The connection must be firewall friendly and without any hindrance to access.


Also, the SCADA must be able to integrate with MES, ERP, quality management, asset management, and other business systems.

Live Dashboards

You must have seen dashboards in advanced SCADA systems, where the operators and engineers can get a great graphical feel of the system.


Just like a Windows PC, it must have configurable icons with drag and drop facility, widgets, split screens, preconfigured gauges, trends, alarms, process points, and movable grids. This makes the operation smoother and provides a great experience in visualization.


Powerful and Rich 2D, and 3D Visualization

If you are designing a large system on SCADA, then rich graphics with a vast variety of symbols, and templates are a must.


It gives the designer huge selection criteria and makes visualization in 2D and 3D smoother and more aesthetic. It should support rich WPF and scriptless, thin-client HTML5 technology which provides consistent visualization.


You must be able to access real-time data on any mobile device or web browser. If the 2D or 3D view is excellent, then the user feels easier to operate the system in an efficient way.


Redundancy Configuration

If you have the requirement of connecting multiple SCADA servers and clients of the same software and communicating with each other, then see whether the required redundancy configuration is possible in the software or not.

It should also be redundant on other modular levels like data connectivity, alarms, and historian.


SMS and Email Alerts

Nowadays, every customer has a requirement to get notifications by email or messages. These demands normally come from managers or higher-level posts employees; because they do not have time to visit the machine every time.


So, the SCADA should be able to distribute enterprise-wide alarm notifications via email, fax, message, phone, or other collaboration platforms like Microsoft Teams.


Advance Alarming

At the IoT level, normal alarms are not a great puller. Enterprise-wide alarms and advanced event management systems are a requirement.

Also, it should be able to filter alarms from any alarm system or link to multiple alarm servers (both real-time and historical) with live data.


Project Documentation

In this way, we understand the features of SCADA in an IoT system.

PLC Program for Mixing Tank

 Create a ladder diagram for controlling a batch mixing process. Implement a PLC program for mixing tank or Mixing Process using PLC Ladder Logic. PLC Program for Mixing Tank Fig : Mixing tank A tank is used to mix two liquids. The required control circuit operates as follows: A. When the START button is pressed, solenoids A and B energize. This permits the two liquids to begin filling the tank. B. When the tank is filled, the float switch trips. This de-energizes solenoids A and B and starts the motor used to mix the liquids together. C. The motor is permitted to run for 1 minute. After 1 minute has elapsed, the motor turns off and solenoid C energizes to drain the tank. D. When the tank is empty, the float switch de- energizes solenoid C. E. A STOP button can be used to stop the process at any point. F. If the motor becomes overloaded, the action of the entire circuit will stop. G. Once the circuit has been energized, it will continue to operate until it is manually stopped. Solution...

What is Relay? How it Works? Types, Applications, Testing

 We use relays for a wide range of applications such as home automation, cars and bikes (automobiles), industrial applications, DIY Projects, test and measurement equipment, and many more. But what is Relay? How a Relay Works? What are the Applications of Relays? Let us explore more about relays in this guide. What is a Relay? A Relay is a simple electromechanical switch. While we use normal switches to close or open a circuit manually, a Relay is also a switch that connects or disconnects two circuits. But instead of a manual operation, a relay uses an electrical signal to control an electromagnet, which in turn connects or disconnects another circuit. Relays can be of different types like electromechanical, solid state. Electromechanical relays are frequently used. Let us see the internal parts of this relay before knowing about it working. Although many different types of relay were present, their working is same. Every electromechanical relay consists of an consists of an Elect...

Chlorine dioxide Analyzer Principle

 Chlorine dioxide measurement Chlorine dioxide (ClO2) is an instable, non-storable, toxic gas with a characteristic scent. The molecule consists of one chlorine atom and two oxygen atoms – represented in the chemical formula ClO2. It is very reactive. To avoid the risk of spontaneous explosions of gaseous chlorine dioxide or concentrated solutions, it is generally handled in dilution with low concentrations. ClO2 is soluble in water, but tends to evaporate quickly. Typically it is prepared on site, for example from hydrochloric acid and sodium chlorite. The procedure provides solutions with approx. 2 g/l ClO2 that can be safely handled and stored for several days. Image Credits : krohne Sensor Parts : Reference electrode Applied chlorine dioxide specific potential Current needed to maintain the constant potential Counter electrode Measuring electrode The disinfection effect of ClO2 is due to the transfer of oxygen instead of chlorine, so that no chlorinated byproducts are formed.
