The OpcUaNetwork is a top-level container component for an OPC UA network in a station. It represents a network of manageable OPC UA client devices.

Within a network you can create multiple OPC UA client devices. This network provides a common monitor that monitors the status of connected OPC UA servers. This component is available in the opcUaClient palette.

Note: Starting with Niagara Niagara 4.14.u1 and Niagara 4.15, the OpcUaServer component provides access to specific aspects of the OPC UA Server based on user roles and permissions as they are configured in the User Service, Role Service and Category Service. These server-side settings are observed when granting access to specific aspects of the OPC UA Server and include more restrictive access for Anonymous users. See OPC UA server, client user authorization for more details.
