CODESYS OPC DA Server by CODESYS GmbH is a classic OPC Data Access solution that enables real-time, bidirectional communication between CODESYS-based controllers and any OPC DA–compliant client, such as SCADA systems, HMIs, historians, and custom applications. It exposes variables from CODESYS projects through a browsable, symbolic namespace, allowing clients to read and write process values with minimal engineering effort.
Designed for Windows environments, the server uses standard COM/DCOM-based OPC interfaces to ensure compatibility with established automation infrastructures. Key capabilities include fast read/write access to process data, subscriptions for timely updates, support for multiple controllers, and robust data type handling for common PLC data types. Access control leverages the underlying Windows security model, helping administrators align connectivity with plant IT policies.
Well suited for brownfield systems and mixed-technology plants, the CODESYS OPC DA Server provides reliable connectivity for operations that depend on classic OPC. It can also serve as a practical bridge during staged migrations to OPC UA, helping reduce driver sprawl, simplify integration, and shorten commissioning time.
