The following information concerns the connectivity of cable tray networks and how the connectivity affects a cable route.

When you route cable, the cable makes a jump from the From Device to the Entry Point and a jump from the To Device to the Exit Point, following an orthogonal path in both cases. The software does not jump between disconnected cable trays or conduit runs. A connection is required between the conduit feature and the cable tray feature. Without the connection, the software does not know to trim the path at that branch.

Where there are gaps between cable tray runs, you should route zero spec cableway (Cws-0). With this spec, no parts are created – only space is reserved. However, the software still makes connections that cable routing will recognize. Hence, you can fill in gaps with this spec and allow the cable routing to have a contiguous network through which to route.

Using zero-spec cableway, a cable path can be routed across a variety of gap conditions.

  • A tight radius turn for which no elbow has been placed

  • A longer radius turn

  • A gap between two trays in the same plane

  • A gap between a horizontal and vertical tray

The following pictures show a disconnected cable tray network. The cable appears to jump over the gaps. Actually, the cable trays are connected using zero-spec cableway, which is hidden in the first picture (and shown in the second picture). The cable path is complete and gives good data as a result.

  • Exit points for cable can be placed anywhere along a tray. A cable can leave a tray at any point, connecting to an equipment or instrument.

  • To check the validity of a cable, open the Properties dialog box for the cable, and go to the Occurrence tab. The Route Status value will be Incomplete or Undefined if the cable is routed through a non-contiguous network. In this case, the lengths cannot be relied upon, and the data is not valid.

  • Zero-spec cableway is used in interference detection to assure there is space for the cables to make the jump across gaps in the tray network.
