Web HMI Products Documentation

Develop Runtime Content
- Runtime Model
  You create a model to build the Runtime structure and content. You set up the types of equipment to use, the instances of equipment to appear in the Runtime context, the information to display about the equipment, and the data sources for supplying both real-time and historical data to Web HMI.
- Model Editor
  Web HMI provides an editor to help you create and modify asset object types and asset objects in your model.
- Set Up Data Source Servers
  You set the data source servers used to populate data in your model.
- Set Up the Model Structure
  Object types define the structure of the equipment pieces within your model. For each object type, such as a StorageTank, you set up all the data variable names, such as TankLevel, that any asset object associated with this type can reuse in its own definition. You also bind mimics to object types for use by their asset objects.
- Define Objects
  Asset objects are the instances of equipment pieces, such as StorageTank1, to appear in the model. For each object, you determine which data variables derived from its object type to reuse, and then define them accordingly.
- Duplicate Objects
  When an object uses similar data variables and contained objects as a configured object, you can duplicate the configured object to create new objects for your model.
- Set Up Runtime Navigation
  Use the Navigation app to visually structure the Runtime hierarchy of objects in Web HMI.
- Change Server Details
  You can remove a server and change its system alias, type, and system name. When you change the server alias name, all objects using that alias are automatically updated.
- Modify Object Types
  You can remove an asset object type and delete and modify its data variable names but you cannot change the name of an object type. All changes made to an object type are reflected in its object instances.
- Remove Contained Types
  When you delete a child from an asset object type, it is also removed from all objects using it.
- Replace Contained Objects
  You can quickly replace contained objects by browsing through a list of similar objects that are assigned to the same object type.
- Modify Objects
  You can remove an asset object as well as change its real-time and historical data sources. You can select multiple SCADA nodes per object.
- Export the Model
  You can generate a file containing the required section headers to get you started if your model is not yet created. You can also export an existing model to make changes to it.
- Make Extensive Model Changes
  If you want to make significant modifications to an existing model, you can export the model, make your changes, and then import the revised model in to Web HMI.
- Import the Model
  After creating or modifying your model, you can import it in to Web HMI.
- Access the Model Template
  The model template, ModelStarterTemplateSteps.xlsm, provides a structure to help you create your model.
- Layouts
  Web HMI provides a set of standard industry layouts that provide a window in to a running HMI/SCADA system. Layouts consist of cards that you can customize.
- Import Mimics
  Mimics are the process diagrams that were created as pictures in the HMI/SCADA system. You import these pictures to use as mimics in the Web HMI layouts.
- Bind Mimics to Assets
  Asset objects can reuse the mimics that you bind to their object types. This enables Web HMI navigation to display the correct mimic in the HMI card in the context of the model.
- Override Mimics
  Asset objects reuse the mimics that you bind to their object types in the model. If you want a different mimic to display for an asset object at Runtime, you can replace the mimic associated with the asset object type.
- Set Up Mimic Target Zones
  Target zones represent areas on a mimic that were set as selectable in the HMI/SCADA system. You set the navigation of these target zones for an operator.
- Define Mimic Control Views
  Use Control Cards to specify which data variables to group together, and which data variables and their attributes to view and modify in auto-generated Control Views.
- Define Trend Data
  Trend Cards show trend-line analysis of variable data in an HMI/SCADA system for a selected time frame. Trend Card charts can display both real-time and historical data.
- Override Attributes at the Object Level
  Control Cards and Trend Cards are available at the object level to allow you to override the attribute values set at the object type level.

Make Extensive Model Changes

If you want to make significant modifications to an existing model, you can export the model, make your changes, and then import the revised model in to Web HMI.

You cannot export the data source and the data variable attributes configured on a Control Card.

In the Administration environment, select the Model Import/Export icon, .
In the Export area, enter a model file name to generate in CSV format.
Select Export.
Retrieve the model file from the Windows Downloads folder.
Make the modifications to your model file.
Import the revised model file in to Web HMI.
