Server Model

This panel shows all objects belonging to the Server Model. All the system Server services will be visible here. The inmation Server service offers a secure OPC server interface (both OPC Classic and OPC UA) so that external OPC clients can connect to the system. If the Server service was installed upon setup (see Installation Guide for details), this local Server will appear in the Server Model.

Other Server instances (either local or remote) can also be connected to the Core. When installing an instance of a Server, it is necessary to specify a Core host that the Server will connect to (see Server service installation instructions for more details). All Server instances connected to the Core service that DataStudio is connected to are displayed in the Server Model. To get started with the Server Model, go to the Server Model Hands On examples.

Table 1. Objects in the Server Model tree
Name	Icon	Description
Server		The Server object represents the system OPC Server service in DataStudio. The object is automatically created in the Server model if a server service is installed during setup (the object will be disabled by default). Configuration of the System OPC Classic server settings and addition of OPC Classic endpoints can be done in the Object Properties Panel. To configure the OPC UA server settings, the OPC UA TCP object is created below the Server object (see below).
OPC UA TCP Server		The OPC UA Server object is created below the Server object and is used to configure the system OPC UA Server settings. Multiple OPC UA endpoint objects can be created below the OPC UA Server object (see below for explanation of OPC UA Endpoint object).
OPC UA TCP Server Endpoint		OPC UA Endpoints are created below the OPC UA TCP Server object in the Server model. They allow the user to individually configure OPC UA server endpoints, including ref:datastudio:infrastructure-hands-on:server-model/connecting-to-the-system-opc-ua-server.html#creating-an-endpoint[security policies and modes].
Web API Server		The Web API Server objects represents the Web API service in DataStudio. The object is automatically created in the Server model if a Web API service is installed during setup (the object will be enabled by default).The communication, authentication and other settings for the Web API can be configured in the Object Properties Panel. Script libraries can also be embedded in the object for use by the Web API.
KPI Server		The KPI Server object is used to represent the Visual KPI Server in DataStudio. Configuration of the Visual KPI Server is done using the Visual KPI Server Manager application, however the creation of the object allows the user to create and configure Dashboards, Widgets and Bookmarks in the Visual KPI web interface directly from DataStudio.
