The SCT Trunk Utilities feature allows you to view and edit device parameters per field controller trunk. You can edit parameters in offline or online mode. Later, you can push offline edits to the field controller through the Trunk Utilities Integration Download feature.

A new feature of Trunk Utilities is an enhanced download workflow which allows for customized interaction with field controllers. Users can access the live devices using the Application Options parameter sheet to view the status of devices and command them accordingly.

Editing CAF Parameters

You can edit CAF file data using the All Items tree or the Rapid Archive wizard.

To edit CAF Parameters through the All Items tree

  1. In the All Items tree, select the MS/TP or IP Integration Trunk for the devices you want to edit.
  2. Select the Parameter Sheet tab in the focus window for the trunk.
  3. In the Parameter Sheet window, select Parameter Sheet.
Note: It is also possible to edit CAF file data for a selected number of devices. See Parameter Sheet Viewer for further information.

To edit CAF Parameters through the Rapid Archive wizard

  1. In the All Items tree, select the parent engine for the MS/TP or IP trunk you want to edit.
  2. On the Facility menu, select Rapid Archive. The Rapid Archive Field Controller wizard appears.
  3. In the View drop-down, select Parameter Sheet.

To modify CAF file data in the SCT archive, in either CAF Parameter Sheet view, click Edit. By default the Parameter Sheet displays five standard VAV CAF parameters: SA-Area, SA-KFactor, CLG-MaxFlow, CLGOCC-MinFlow, and HTGOCC-MinFlow. You can create custom CAF parameter columns and views using the Manage Views selection from the View drop-down list.
