Valuable plant data often remains isolated inside OPC DA servers because Windows COM/DCOM makes it difficult to access securely across modern OT and IT environments.
Litmus OPC Fusion provides a non-invasive path forward. It reads from existing OPC DA servers and republishes their data through OPC UA, making it available to Litmus Edge and other standards-based clients.
OPC Fusion connects to OPC DA servers, maps their tags into OPC UA nodes, and exposes the data through a secure OPC UA server.
Litmus Edge can ingest that data through the OPC UA Client Advanced driver, bringing it together with signals from PLCs, historians, and IT systems for contextualization, storage, analytics, and downstream integration.
Connect, configure, secure, and operationalize OPC DA data.
NON-INVASIVE OPC DA CONNECTIVITY
OPC Fusion runs alongside existing OPC DA servers, preserving stable systems while making their data available to OPC UA clients.
