Extending the simple network and creating a ring

Turn a simple InOne network into a redundant ring, then tidy up the drawing

Extend the simple network from Creating a very simple network in the InOne Design Tool into a redundant ring. You give each HAN its own name and power, close the ring back to the HDN, and tidy up the drawing.

Before you begin: open the design with HDN-A and the three HANs from the first article, or import its configuration file.

Set the name and power of each HAN

  1. Double-click a HAN to open Edit HAN.
  2. Change the Name and the Power (W), then click Save. In this example, the second HAN becomes A2 with 50 W and the third becomes A3 with 85 W.
    Edit HAN dialog with name A2 and power 50 W
  3. The new names and power values show under each HAN.

Arrange the nodes as a ring

Click and drag the HDN and the HANs so they form a circle. Leave a gap between the last HAN and the HDN for the ring cable. Moving nodes does not change the cable lengths.

Close the ring

  1. Right-click the last HAN (A3) and click Close ring.

  2. In Close redundancy ring, select the Ring cable type and Size, and enter the Ring cable length (m). This example uses Blowable/Ducted, 3 mm2 (24 Fibers) and 200 m.
  3. Click Close ring.

Check the ring

  • The ring cable is drawn as a green dashed line from the last HAN back to the HDN.
  • The system card shows Can close ring: YES. This means the system can still be powered from the ring side.
  • Hover over the ring cable to see its size, length, ring power, resistance and current.

Tidy up the drawing

  • Shape a cable route: right-click the middle of a cable. A dot appears. Drag the dot to bend the cable. The cable length stays the same.
  • Move labels: drag a cable length label along its cable, or drag a HAN label to another side of the HAN.

  2. Type the note, for example This is a simple ring topology network, and click Add note.
  3. Drag the note to where you want it, for example the middle of the ring.
