Use Wiring Rules

AVEVA Electrical uses 'Wiring Rules' to auto generate typical equipment wiring/cabling. Using the Wiring Rules features can save many hours otherwise required to build devices and their associated terminal arrangements, cables, terminations etc. in Electrical Wiring Manager.

By applying a Wiring Rule to an item, the following are defined:

• Terminal arrangements - the number of terminals, their markings and sequence.

• Default signal numbers (wire numbers) to be used on wire terminations.

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

• Default cable number, which can based of the tag number fields of the items at either end of the cable.

• Default wire terminations - how the cable is connected to the terminals (e.g. core 1 to terminal 1, core 2 to terminal 2 etc.) at either end.

When a wiring rule is applied to an item, the terminals are created, and the cable is created and terminated at both ends. Electrical Wiring Manager always uses the next available spare terminals.

For example, a motor could have three cables:

• Motor Power Cable

• Anti-condensation heater

• Over temperature protection (thermistor/klixon etc.)

The application of a wiring rule will create the three cables from the supply item to the motor, and generate their terminal arrangements.

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

• Re-running wiring creation using a new or changed Wiring Rule - this enables users to update terminal arrangements, cable type, terminations etc.

• Edit the cable details/type using the Cable Schedule user interface.

• Edit terminations using the Electrical Wiring Manager Terminations User Interface.

Wiring Rules are assigned from Electrical Wiring Manager's Equipment List. Refer to Create Wiring.

Wiring Rules can be modified or new rules created by a user. Refer to Wiring Rule Definitions.
