Add Equipment

To add equipment to the new rule, right-click on drawing canvas. The following menu is then displayed:

Click Add Equipment.

Two further options are then displayed:

• Field Device - used to select from the Wiring Manager Field Device catalog.

• Junction Box - used to define a terminal strip arrangement.

  When a Wiring Rule is assigned to an instrument, all the rule's field device terminals, cables and terminations are auto-created. A Wiring Rule must always contain at least one Field Device from the Field Device Catalog.

If you select Field Device, the Equipment window is displayed:

Enter a DataLink to represent the Field Device Tag Number from the Equipment No drop-down list.

There a two different types of field device tags:

• {TAG} will create a new field device using the current instrument tag number.

• {TAG?} will cause Wiring Manager to prompt the user for another instrument field device that already exists in the Wiring Manager project (and is an instrument assigned to the current instrument tag's loop). This type of tag is not created as it must already exist. This second option enables users to wire between two different tags in the same loop (example: a Thermocouple to a Temperature Transmitter, where a user would first create the Transmitter with one Wiring Rule then create the Thermocouple with another Wiring Rule using the {TAG?} to represent the Transmitter in the first Wiring Rule).

Select a Field Device by clicking the button next to the Type field.

The Select a Field Device Terminal Configuration window is then displayed:

This window shows all Field Devices defined in the Wiring Manager Field Device Catalog. Users may add to this list by defining new Field Devices in the Field Device Catalog.

Select by double-clicking on a Field Device image on the Graphic tab or its record on the List tab or by clicking on the required image/record and then click Select.

If Junction Box is selected from the pop-up menu, this version of the Equipment window is displayed:

Select a DataLink to represent the Junction Box (or Equipment) Tag Number from the Equipment No drop-down list.

Note: A DataLink {JB1} is used to represent any existing equipment. Existing equipment is not created but is assigned to the tag in the Wiring Rule using Junction Box assignment.

Enter the number of terminals in the No. of Terminals field.

Define just enough terminals to enable all the field cable wiring to be terminated as required by the Wiring Rule definition.

Wiring Manager uses {JB1} tag to make the Wiring Rule find the next available spare terminals in the Junction Box or Equipment assigned to the tag. A DataLink of type {JB} never creates equipment (or equipment terminals), it uses the equipment assigned to the current tag as the 'Junction Box'.
