System Platform component descriptions

The System Platform framework consists of server-side configuration and deployment related components. In System Platform, these components include:

• A centralized object repository called the Galaxy Repository

• An integrated development environment (IDE) for engineering, configuration, and maintenance

• Run-time nodes

• A database to store historical data (the Historian)

  Engineering Station Runs the tools necessary to develop and configure the application, such as the System Platform IDE, Industrial Graphic Editor, and InTouch WindowMaker. There can be multiple engineering stations for multi-user development teams.

  Galaxy Repository Runs the Galaxy Repository service and hosts the configuration project database. There is only one Galaxy Repository per Galaxy.

  Historian Server Runs the Historian Server software and hosts the history and alarm databases. Typically, there is only one historian server per Galaxy, but there can be more than one if needed, such as in largely distributed Galaxies hosting local historian servers per location.

  Application Object Server Computer where application objects operate in run time after being deployed. There can be multiple Application Object Servers (AOS) for load distribution, redundancy, or both.

  Device Integration Server Computer connected to the control network and running the corresponding Communication Drivers, or legacy OI Servers. A single Device Integration Server can run multiple drivers, or you can have multiple Device Integration Servers, depending on the control network topology.

  RDP Server The RDP Server allows the supervisory clients to run the operator’s interface through a RDS session.

  InTouch Access Anywhere (ITAA) ITAA allows the supervisory clients to run the operator’s interface via an HTML5 compliant browser.

  ITAA Secure Gateway Provides secure web remote connections from InTouch Access Anywhere clients running on unsecured networks to internal network resources. The Secure Gateway provides authentication and authorization services as well as data encryption.

  ITAA Authentication Server Authenticates InTouch Access Anywhere users before they are allowed to connect to internal resources.

  Supervisory Client Thick client Runs the operator's interface or HMI through OMI runtime tools installed in a workstation. There can be multiple visualization stations.

  RDS or Web Client Runs the operator's interface or HMI through OMI runtime tools through a RDS or HTML5 web browser. There can be multiple visualization stations.

  License Server Provides the functionality for users acquire, store, maintain, and serve licenses to all installed AVEVA Enterprise software.

  System Management Server Encrypts communications between all System Platform nodes.
