Cables attached to cable drums cannot be claimed or merged to or from As-Built/Project Center or a Project. If a cable has been assigned to a drum, you should disconnect the cable
before claiming or merging the cable. Failure to do so will result inconsistencies
in the drum data.
The cable drum feature allows you to efficiently use cable drums, and setup an organized method of cable drum assignment. The cable drum feature handles both the optimization of existing cable drum allocations (purchased drums) and the assignment of new cable drums when necessary (Design drums). The cable drum feature allows you to perform cable drum assignment both automatically and manually. The cable drum feature requires that you define pulling areas in your <plant> where the cable drums are concentrated. This can be done in an Engineering plant, Owner Operator plant (As-Built), or project. From these areas you perform the assignment of cable drums for the cables.
The pulling area that you define here does not have the same functionality as the <area> in Smart Instrumentation plant hierarchy. The pulling area is designated for cables and cable drums only.
The steps required to set up a fully functional cable drum assignment are as follows:
-
Define the pulling areas where the cable drums are placed.
-
Associate cables with the predefined pulling areas.
-
Define drum attributes for cable types.
-
Create the cable drums that will eventually be assigned to your cables. This includes both adding the cable drums that already exist in your <plant> and adding the cable drums that you need to purchase to complete your required cable drum inventory. You can also perform this automatically in a cable drum assignment.
-
Select the cables that you want to assign to the cable drums that you have created (even if the drums have not been purchased yet).
-
The last stage is to assign cables to cable drums. At this stage the cable drum feature automatically adds new cable drums as required.
-
We recommend that when working in an As-Built plant with projects, you carry out the workflow for creating cable drums from within the project.
-
Pulling areas are common to the As-Built and all its projects.
