Structure of a SCADA System
The structure of a SCADA can be divided into:
Supervision Layer, fundamental for operator interaction, may include the following elements:
- Supervision client or operator screen.
- Development client or development station.
Data Processing Layer, crucial for processing and managing information, composed of:
- Intercommunication system between different stations
- Alarm system
- Reporting system (optional)
- Historian system (optional)
Data Acquisition Layer, responsible for data collection, includes:
- Communication drivers
- Elements to communicate with other software such as OPC servers, databases, APIs, etc.

Components of a SCADA System
Generally, a SCADA system has the following components:
- Controllers or communication drivers: Responsible for reading/writing data from physical elements like PLCs, RTUs, sensors, etc.
- Central Server or Application Server: Responsible for managing communications between all elements of the SCADA system.
- Historian: Element responsible for storing data in temporal format for later consultation.
- Supervision Client: Interface between people and the SCADA system, to monitor and modify/control system signals in real time.
- Development Client: Operator interface designed to modify SCADA configurations.
Importance of a SCADA System
SCADA software is a critical component that directly influences the effectiveness and efficiency of a SCADA system. There are several widely used SCADA software in the industry that offer diverse functionalities to meet the specific needs of each system. Choosing the right software is crucial to maximize the performance and security of the SCADA system.
Understanding the structure and components of a SCADA system is fundamental for any professional in the field of industrial automation and control. Choosing the right SCADA software and having a solid SCADA platform are essential for the success of any SCADA implementation. By staying informed about the latest trends and technologies in SCADA software, professionals can ensure their systems are robust, flexible, and secure.
