5.2.2 Operation

Figure 6: Use case - Operation

Use Case:

User Login

Brief Description:

A person of specified actor type logs into the Frame Application. If verification fails the person may act as an "Observer" actor only.

GUI:

Part of the Frame Application

Print:

No support

Device Connection:

Not established

UserLevel

Observer:

Depends on the Frame Application

Operator:

Accessible

Maintenance:

Planning Eng.:

UserFlag

Administrator:

OEM Service:

Accessible with extended functionality (see below)

Included Use Case:

DTM-Specific Login

Brief Description:

Access to manufacturer specific information e.g. production codes, changes log

GUI:

Part of the DTM

Print:

No support

Device Connection:

Typically needs an established connection

UserFlag

OEM Service:

Accessible only for OEM Service

Figure 7: Realization of use case "User Login"

Use Case:

Online View

Brief Description:

This use case offers a complete set of operations for viewing of device parameters and status.

GUI:

The GUI is part of the DTM. The Frame Application can offer online views for a group of devices.

Print:

Online View should always support print function to create documentation.

Device Connection:

Needs an established connection to one or more devices
(Adjust SetValue may influence device data)

UserLevel

Observer:

No access

Operator:

Accessible

Maintenance:

Planning Eng.:

UserFlags:

No changes

Included Use Case:

Parameter Set Online View

Brief Description:

Enables the actor to load parameters from the device for viewing and documenting (printing).

Included Use Case:

Adjust SetValue

Brief Description:

Enables the actor to adjust the SetValues of a device (e.g. positioner, controllers).

Included Use Case:

Online Status

Brief Description:

Use case for viewing and analyzing the current device status.

Included Use Case:

Online Trend

Brief Description:

Use case for generating and watching trends of dynamic online values.

Included Use Case:

Plausibility Check

Brief Description:

Every time the device parameters or the configuration data is changed a plausibility check is automatically performed. As long as the plausibility check fails, the data cannot be written to the device.

Included Use Case:

Identify

Brief Description:

Displays identification of device instance information e.g. address, TAG, Fieldbus-Rev., DD-Rev., Firmware. This information is protocol dependent. It also may contain device type specific information. Further information may be provided: references to documentation, area to add comments to the device instance. Refer to Device Identification chapter in protocol specific FDT-JIG-Annex specifications.

Use Case:

Audit Trail

Brief Description:

Use case to enable the actor viewing and deleting audit trail data.

GUI:

The component, which supports audit- trail, has to provide an adequate GUI.

Print:

Printing for documentation purpose as a need for audit trails and therefore has to be supported.

Device Connection:

No connection necessary

UserLevel

Observer:

No access

Operator:

Accessible for viewing only

Maintenance:

Planning Eng.:

View, export and delete

UserFlags:

No changes

Included Use Case:

DTM-Specific Audit Trail

Brief Description:

Every DTM might support an audit trail on its own.

Included Use Case:

FA-Specific Audit Trail

Brief Description:

The Frame Application may implement a system global audit trail using internal data and named DTM properties exported from the DTM via the IDtmAuditTrailEvents interface.

Figure 9: Realization of use case "Audit Trail"

Use Case:

Archive

Brief Description:

The "Archive" use case describes the access to a Frame Application archive for viewing and data analysis.

GUI:

The component, which supports archive functions, has to provide an adequate GUI.

Print:

Every archive component should support printing too.

Device Connection:

Not necessary

UserLevel

Observer:

No access

Operator:

Accessible for viewing only

Maintenance:

Planning Eng.:

View, export and delete

UserFlags:

No changes

Included Use Case:

Historical Trend

Brief Description:

The archive operations may support visualization of historical data (for example trending).

Included Use Case:

Historical Data Analysis

Brief Description:

Some Frame Applications and DTMs may support extended operations to analyze historical data.

Figure 10: Realization of use case "Archive"

Use Case:

Report Generation

Brief Description:

The print function of a use case can normally be started from its GUI.

In addition to printing the actual view of a GUI some Frame Applications may implement a configurable documentation mechanism which enables the actor to generate reports. This report may be generated by combining the prints of several use cases or several devices.

For example a report could be generated containing "Online View", "Audit Trail" and "Online Operation" printouts for one device or a report may be generated containing the configuration of a HART multiplexer and its clients.

GUI:

Frame Application

Print:

Frame Application in combination with one or more DTMs

Device Connection:

Depends on the type of report

UserLevel, UserFlag:

The printed information may depend on user level and user flags.

Use Case:

Asset Management

Brief Description:

Frame Application provides mechanism for asset management

GUI:

The component, which supports asset management functions, has to provide an adequate GUI.

Print:

Frame Application supporting this use case should support printing, too.

Device Connection:

Not necessary

UserLevel

Observer:

No access

Operator:

Accessible for viewing only

Maintenance:

Planning Eng.:

View, export and delete

UserFlags:

No changes
