What is OPC UA & OPC DA?
OPC UA (Open Platform Communications Unified Architecture) is a platform-independent, secure industrial interoperability standard. OPC DA (Data Access) is its predecessor, still common in existing installations.
How SCAIQ™ implements it
SCAIQ Connect provides OPC UA and OPC DA connectivity as part of its extensible driver framework, enabling interoperability with OPC-compliant systems, PLCs, and third-party software.
Use cases
- Interoperating with existing OPC-compliant systems
- Connecting to controllers and devices that expose OPC servers
- Cross-vendor data exchange without protocol-specific drivers
