Namespaces

The namespace is part of the node identity used to address a specific node. A namespace is
defined by some organization or company and is responsible for managing the identifiers of all
nodes defined in the namespace.
The namespaces supported by a OPC UA server is presented in the NamespaceArray of the
Server object. When addressing a node in the address space the position (array index) in the
NamespaceArray is used to point out the namespace that the node belongs to.
The index 0 of the NamespaceArray is reserved for the OPC UA namespace and the index 1 is
reserved for the local Server. Further indexes can contain any namespace supported by the
server. As the Anybus CompactCom implements the OPC UA Device Integration model, the
namespace of this model is present in the NamespaceArray. The Anybus CompactCom also has
its own DeviceType defined and is part of a namespace managed by HMS Industrial Networks.
The table below shows the namespaces supported.

Description
OPC UA Foundation
Local server namespace. Globally-unique logical name for
a server within the scope of the network in which it is
installed. The hostname is used as a component of the URI
if configured. If the serial number of the application is
available, this can be used, otherwise the serial number of
the Anybus CompactCom is used. This namespace string
can be replaced by the host application for branding
purpose.
OPC UA Device Integration (DI)
The namespace of the device model that is inherited from
the Device Integration (DI). Default is the CompactCom 40
device model defined by HMS Industrial Networks. The
host application can configure the namespace URI for
branding purpose.
