Using Wiring Rules to Create Data

AVEVA Electrical uses 'Wiring Rules' to auto generate typical equipment wiring/cabling. Use of Wiring Rules features can save many hours otherwise required to build device terminal arrangements, cables, terminations etc. in Electrical Wiring Manager.

When a Wiring Rule is applied to equipment, the following are defined:

• Terminal Arrangement - number of terminals, their markings, sequence.

• Default wire numbers to be used on wire terminations.

• Default Cable Type - type of cable (individual cores, pairs or triad etc.), whether shielded/screened, and whether armoured etc.

• Default Cable Number, based on the equipment tag number fields from Electrical Engineer.

• Default Wire terminations at equipment - how the cable is connected to the equipment terminals (core 1 to terminal 1, core 2 to terminal 2 etc.), and how the cable is connected at the other end (i.e the load or supply end).

When Wiring based on a Wiring Rule is created, AVEVA Electrical creates all the above automatically. Prior to saving this data AVEVA Electrical also enables users to:

• Change the default Cable Number created by the Wiring Rule.

• Select equipment the cable will terminate to at the other end.

After accepting defaults (or making changes as required) the equipment and terminals are created, cable created and terminated at both ends (assuming the load/supplies have been specified). At the other end, AVEVA Electrical always uses the next available spare terminals.

At any time after a Wiring rule is applied, the data that has been generated can be edited by:

1. Re-running the Create Wiring command using same Wiring Rule - this enables users to reassign a Cable No etc.

2. Re-running the Create Wiring command using a new Wiring Rule - this updates terminal arrangements, cable type, terminations and enables users to reassign a Cable No etc.

3. Edit the cable details/type (using the AVEVA Electrical Cable Schedule user interface).

4. Edit terminations (using the AVEVA Electrical Terminations editing user interface).

Create Wiring

Facilities for creating wiring for loads are available on the Load Details window. This window can be accessed by:

• Either clicking on the button in the Equipment No field in the Drawing Information window (see View and Edit Drawing Information window).

• Or clicking the button in Equipment No cell which is displayed when the mouse cursor is hovered over that cell in the Drawings List.

The Options window is then displayed.

Click the Edit Detail option to open the Load Details window. Facilities for creating wiring are located on the Detail tab. Refer to Electrical Engineer documentation for further information.
