10.3.2.How to: Create HCS Diagram

HCS Diagrams

HCS diagrams visualize controllers, controlled processes, control actions and feedback. Add new elements to diagrams or modify already existing elements on your diagrams.

HCS Diagrams reside under a HCS Model and the STPA Module supports multiple diagrams for one HCS model.  All elements, with the exception of annotation elements, that are created on a diagram are stored as part of the respective HCS Model.

How to: Create HCS Diagram

  1. Select the HCS Model for which a new HCS Diagram shall be created in the STPA Project Overview
  2. Click the ‘++’ icon to create a new HCS Diagram. Alternatively, you can create a new HCS Diagram via the menu entry “New HCS Diagram” shown in the context menu of the HCS Model
  3. Expand the node representing the HCS if necessary, by clicking the little arrowhead to the of the icon. You will notice a new element representing the newly created HCS Diagram. By default, the HCS Diagram is labelled ‘New HCS Diagram’.
  4. Double click the ‘New HCS Diagram’ to open its canvas in the workspace. You can save your progress now to allow the name to save for the tab and in the tree (Ctrl+S or save icon at the top-left).

How To: (Re)name the HCS Diagram

After creating the new HCS diagram, entering a unique name is necessary, because the name is displayed in the register tab and the STPA Project Overview tree for easy identification. Under the Properties panel the description field may be used to capture an optional description.

To name or rename the HCS Diagrams perform the following steps:

  1. Open the HCS Diagram by double clicking the HCS Diagram under the Model in the tree.
  2. Make sure nothing is selected on the canvas and rename the HCS Diagram using the Properties pane

The user interface for Models and Diagrams provides the following work areas as default docked panes. All of the panes can be rearranged, floated, resized, added or removed as the user prefers.

  1. The Canvas is displayed in the center and it is used for modelling the HCS diagram with the “Diagram Elements”. The canvas also contains a Canvas Toolbar to aid in the customizing of the panes, including a zoom in/out scale for the canvas.
  2. The Toolbox on the upper left-hand side of the canvas contains the Diagram Elements and Connectors for use on the canvas via ’Drag and drop’.
  3. The Browser on the lower left-hand side of the canvas shows the relationships of the currently selected element on the canvas.
  4. The Properties panel on the upper right-hand side of the canvas shows the properties of the currently selected element on the canvas.
  5. The Canvas Overview on the bottom right displays the complete Diagram in a miniature form, while highlighting the visible area of the canvas and providing a pan and zoom function.

Note: The screenshot shown above, along with the described locations of the individual panels, represent the default positions. Un-docking, relocating, and docking in a new position is allowed and easy to do.

How to: Pan and Zoom and Scale Canvas

The STPA Module provides several ways to scale the visible area along with pan and zoom around the diagram canvas.

Canvas Toolbar Scaling

The Toolbar of the Canvas provides a sliding scale for the canvas to adjust the size of the viewing area.

Canvas

Use the scroll button on your mouse to enlarge or shrink the canvas viewing area (zoom in/out). Another great way to move around the canvas when your diagrams get to be large is to hold the ‘Ctrl’ key and the left click button to “grab the canvas”, then simply move around as you like. Release the left click button to set in place.

Canvas Overview Pane

Inside the Canvas Overview you should notice a grey, shaded box that represents the canvas viewing area. Again, use the scroll button on your mouse to enlarge or shrink the canvas viewing area (grey box within the Canvas Overview). Use the left click button to grab the grey box in the Canvas Overview and move around the canvas. Release the left click button to set the viewing area on the canvas.
