Subnet discovery is based on a special network protocol that allows OPC UA Clients to find OPC UA Servers connected to the local subnet. The list of servers can be filtered by capability acronyms.
- Automatic detection instead of querying each node on the network
- Filtering by capability to lookup the appropriate Servers.
- Requires that the network has multicasting enabled.
The Discovery Client Facet includes two alternate Conformance Units (CUs) for this capability.
