IIoT – The Story Behind Upgradation from SCADA

IIoT – The Story Behind Upgradation from SCADA

One of the most popular words these days is IoT. We are always hearing stories about how all devices will be connected by the year 2025. People are more interested in knowing about the Internet of Things and how all smarter devices is bringing a big change in this world. IoT and cloud both have varied things to offer than only customer grade conveniences. Both cloud and IoT combined have some specialized applications in the industrial sector that created IIoT or Industrial IIoT. But at present, there is already a technology functioning for more than 20 years. This technology is SCADA (Supervisory Control and Data Acquisition). It is a system that posses software and hardware elements that facilitates the industrial organizations to Have easy control over industrial processes both locally as well as remote locations. Supervise, collect and process all real-time data. Have direct interaction with some devices like sensors, pumps, valves and even more through software called human-machine interface. Recording the events into a soft file. So, when remote supervision and asset control is already done with SCADA, then what changes or improvement will IIoT will bring? This is one of the common and obvious questions that are arising in mind of most of the people and industries. Well! The answer to this question we can get by comparing both for industrial use. This will help in clearing the reason why up-gradation from SCADA is required.
So, when remote supervision and asset control is already done with SCADA, then what changes or improvement will IIoT will bring? This is one of the common and obvious questions that are arising in mind of most of the people and industries. Well! The answer to this question we can get by comparing both for industrial use. This will help in clearing the reason why up-gradation from SCADA is required.
Device integration: While using SCADA system integration of devices is not that much easy, sometimes even with devices from the same manufacturer but with different versions. For the development of flawless programmability for all devices and sensors, integration is required and also there is a need for a horizontal platform that can easily operate on varied devices. But on the IoT ecosystem, it depends largely on device integration. The main aim of IIoT is to facilitate easy communication across devices, no matter what version or model they are. IoT makes use of protocol like MQTT to facilitate communication across devices. Cost of system possession: With SCADA, businesses can keep data up to a certain extent and after that limit, this data will be overwritten by new data. This means to store more data industries have to buy more servers with more capacities. Same with software licensing also, for getting more features, SCADA users have to invest in additional licenses for services and have to pay for system up-gradation. But on the other hand, IIoT helps in decreasing the cost for industries as they cut off the requirement of additional software licensing as well as up-gradation by utilizing cloud services. Data insights: With SCADA, industries will have limitations while analyzing historic data. It does not put much stress on the analysis of data that are produced by business daily. The data stored in the SCADA system does not offer much value to the industries and also does not make any contribution to decision making. It is because they do not produce the contextual information. But IIOT shines much better. They store data from all businesses and apply big data processing and machine learning to make some predictions on efficiency and important outcomes. This easily understandable insight helps the company to decrease the sudden equipment failures, know the maintenance requirements and obtain high outcomes from the assets. Scalability: As we know that the SCADA system does not stores or analyze data, it may leave some of the important information from devices. The main cause of not connecting devices is the performance and security of the system. When the user number increase, the band with needed to properly function also increases and this, in turn, increase the total cost of the company. But with IoT, everything is stored in the cloud and can be accessed very easily from any place. Other than that as extra devices can be connected easily, it offers access to every data that can play a major part in deciding for businesses.
So, now with all these benefits of IIoT, the question comes whether it will replace the whole SCADA system?
Well! The answer is yes, even if it may take time as it requires uprooting the whole system and installing another, but it will get upgraded. As IIoT is making things much easier and with less cost, therefore industries will prefer to upgrade.
