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.
