A node instance is an instance of a node where component
instances (see Section 23.5, “Component Instance”) may
reside. In the UML metamodel
NodeInstance is a
Instance and is specifically an
instance that is derived from a node.
A node instance is represented on a deployment diagram in
ArgoUML as a three dimensional box labeled with the node instance name
(if any) and node type, separated by a colon (
It is the presence of the colon (
The details tabs that are active for node instances are as follows.
Standard tab. The

Beware that in the current release of ArgoUML, the bounding box just refers to the front face of the cube. This means that the three dimensional top and side may be ignored, for example when determining the limits of a diagram for saving graphics.
Standard tab, containing just the name of the node instance.
A node instance should not generate any code, so having this tab active is probably a mistake.
