MergenHub OPC UA Server — a single address space
Data from every protocol driver unifies into one standard OPC UA address space. SCADA, MES and DCS clients read and write from a single endpoint.
What it does
The OPC UA Server is the heart of MergenHub: it aggregates Modbus, S7, DNP3, 61850 and all other sources into one standard address space. Any compliant OPC UA client (SCADA/MES/DCS) connects through this single endpoint. It has been tested at 450k-tag scale.
Key features
Multiple endpoints (multiple "Server Endpoints") bound on different ports and security policies; per-user access; certificate trust; in-place address-space reload. Read and write are fully supported.
Core capabilities
Single address space
All drivers and virtual tags in one OPC UA tree; including _Aliases and _System.
Multiple endpoints
Bind multiple endpoints on different port/security policy; endpoint restriction enforced via port→policy.
Policies & certificates
Sign/encrypt security policies, user authentication and certificate trust management.
450K+ tags
Proven performance and memory management at hundreds of thousands of tags.
In-place reload
Address-space reconfiguration without a restart; channel-scoped incremental reload.
Read & write
Full read and write handlers; sampling and session management.
