Web HMI Environments

Web HMI contains a Runtime environment, an Administration environment, and the Application Assembler.

Runtime Environment

Operators use the Runtime environment to interact with a HMI/SCADA system. Runtime content is linked directly to data sources, such as Historian.

Administration Environment

GE administrators configure the production runtime content for operators in the Administration environment. GE administrators perform the tasks needed to get data flowing and alarms appearing in the Runtime environment.

Application Assembler

GE administrators manage visualization, which includes creating and modifying mashups, masters, menus, style definitions, and state definitions in the Application Assembler. For information about managing visualization in Application Assembler, see ThingWorx documentation.

GE administrators also handle security, which includes creating and modifying users, user groups, organizational-level security, and Active Directory authentication in the Application Assembler.
