SCADA Driver Development | Native Driver Programming in ATDriver

SCADA driver development is a critical part of industrial automation, allowing SCADA systems to communicate directly with PLCs, sensors, and other field devices within a modern cloud SCADA architecture. In the ATSCADA ecosystem, ATDriver Server provides a powerful foundation for building custom and native drivers with high performance and flexibility.

This article focuses on how to develop a native SCADA driver in ATDriver, including architecture, programming requirements, and practical implementation based on available source code.

Understanding Plug & Play SCADA Driver in ATDriver

ATDriver Server is designed with a Plug & Play driver architecture, allowing developers to easily integrate and extend communication drivers.

Key features:

• Flexible driver integration without restarting the system
• Modular driver design using DLL components
• Easy expansion with custom native drivers
• Compatible with multiple industrial protocols

With this architecture, developers can quickly build and deploy new drivers tailored to specific devices or communication standards.

• Protocol structure implementation

Programming Requirements for Native SCADA Driver

To successfully develop a SCADA driver in ATDriver, you need the following technical skills:

Programming Languages

• C# (.NET)
• VB.NET

Development Environment

• Microsoft Visual Studio

Technical Knowledge
