Fault Diagnostic Tab

Once you have added the FDDWorX tab to the asset's Equipment form in AssetWorX (and then added faults through the Fault Definitions tab) you can add Diagnostic Symptoms Mappings. The image below shows the initial state of the Fault Diagnostic tab within the FDDWorX tab within the selected asset's properties.

Note: This tab is also available for equipment classes. All equipment classes are defined in AssetWorX in the Equipment Classes node. In AssetWorX, you can define and use equipment classes as templates for creating nodes in the asset tree. You can also use aliases in your equipment classes; these aliases will prompt you for actual properties for equipment as you use the equipment classes to define nodes in the asset tree. For more information, refer to the Introduction to Equipment Classes (Templates) and Creating Equipment Classes for Use as Templates topics.

To Select a Diagnostic Model

If you have already created at least one Diagnostic Model in the FDDWorX provider in the Workbench, you can select one by clicking on the pulldown menu at the top of the tab window, as shown below.

If you selected an existing diagnostic model, you'll notice that its Symptoms now populate the Diagnostic Symptoms Mappings grid within the Fault Diagnostic tab, as highlighted below. You can now set a Mapping Type, either Alarm or Expression, for each Diagnostic Symptom.
