What is the purpose of SCADA in an industrial process?

Functions of SCADA in an industrial process
Industrial process monitoring with the help of SCADA

Supervisory control and data acquisition (SCADA) is software that can be used to control the industrial process. SCADA can monitor a plant or equipment in industries such as oil and gas, chemical plants, etc. So SCADA is software that is used to monitor the industrial process and if any changes should be made in the process then it would send a command signal to the PLC or other device.

The major functions of a SACDA are data acquisition, networked data communication, presentation of data, and control. We can control or monitor an entire plant with the help of SCADA. In case if there is any fault like a leak in a pipeline then the SCADA system would transfer this data to the home station and also would take the necessary action and control. SCADA would transfer command signals to the PLC or DCS according to the received field data.

How can we select SCADA software?

  • It must be compatible with different operating systems
  • OS supported must be considered
  • It must be selected according to the type of communication protocol
  • System-upgradation
  • Safety and reliability
  • It must be selected according to the drivers in the SCADA system
  • It should be adaptable

Comparison between free SCADA software

1.Fernhill SCADA

We can use this SCADA software to monitor and control our process, we can use this SCADA software for the major industrial processes from hydroelectric to wine production. This SCADA performs really well according to the client-server architecture. This software also provides certain data access interfaces such as .net API, Java Api, OPC Classic, OPC UA, and ODBC. This SCADA software also provides better security so that our equipment will be protected from unauthorized access.

2. Tatsoft factory studio

By using this tool, we would be able to design industrial applications securely and powerfully. There are many features for this software such as MQTT broker, audit trail, and a lot more. We can program scripts in C, VB.Net, javaScript, and python. It has many built-in protocol drivers to PLCs, DCS and it would also support other industrial standards too.

3. Rapid SCADA

This is open-source software that can be used for industrial automation, this software has many tools which will be useful for quick monitoring and controlling. This software can be used for large distributed industrial automation systems. It has the ability to interact with the external database in real-time. This software has many features such as an automatic control module, rapid gate module, remote troubleshooting, and a lot more.

4. Ignition SCADA

This type of software can be used with large industries, this is a web-based solution that can be used to control the process remotely. By using this software we can check data across different locations.

Supported protocol – Modbus, Ethernet, UDP, and TCP

5.Open APC

This is an open-source process control and it can be used to do many automation processes. We can use this software for process stabilization and also improve the process. So it would do the data collection, data analysis, and also the interpretation of the process and by doing this the process monitoring can be easily done. We can do the offline and online analysis by using this software

6. Open SCADA

This type of SCADA software has good modularity and scalability, by using this SCADA software we can check and visualize the industrial process. This software would provide better control over modules, and also it would provide access to the database. It has various communication modes such as MODBUS, OPC-UA to interact with the external environment. Data acquisition from external sources such as controllers and sensors is also possible.

7. WinTr

The WinTr SCADA software can be used to monitor and also to save the process data. This software can be connected with OPC clients, Profinet, Modbus.
