The tool Order passing objects in node under Edit > Node/manhole is used to determine the order which an object, for example a cable, passes through a node, for example a manhole. In many cases this needs to be done when the cable is passing the manhole more than once. A typical case is a so called inverting cable, which is passing through a joint manhole, goes to a customer node, where it turns, goes back to the joint manhole and then continues in the network. When you try to split an inverting cable an error message might occur that states "Failed to perform split. No path found to end object". The system can not unambiguously interpret (trace) how the cable is passing through the network. This is why the tool Order passing objects in node needs to be used.

 

 

 

Example of inverting cable: Opto cable OK 1 is passing twice through manhole BR 1 and is turning back in the customer node AP 1.
Schematically it can be said that OK 1 runs MS 1 -> BR 1 -> AP 1 -> BR 1 -> FN 1.

Order passing objects in node

1.Select Edit > Node/manhole > Order passing objects in node.

2.Select the node or manhole that the cable passes through twice, in the example above it is the manhole BR1. A dialog is opened which shows the nodes and the passing objects that is affected.

3.Select a node in the list Nodes. In the list for passing object the passing cable is shown. Note that the objects are highlighted in the map in the dialog as support.

4.Select a cable in the list Passing objects. In the list Object, all nodes from which the cable runs is listed. Note that one of the objects are listed twice since this cable goes out and then comes back from the node (in two different pipes).

5.The task is now to arrange the objects and describe how the cable runs through the node. You can start with the "outer" nodes or the "inner" nodes.

6.Select a manhole in the Object list and move it to the top of the list by using the buttons to the right in the dialog.

7.Select the cable that goes from the manhole to the cable. Use the field ID to identify the right cable, or the pipe in which the cable runs out from.

8.The cable/pipe that goes back to the manhole is placed in the last row in the example below. The dialog is showing the order of passing objects for the manhole.

9. Press Save and close the dialog by using the cross in the upper right corner.
