Create Wiring for Field Devices

Tag No

The instrument tag number - non editable.

Note:
Although the specified Wiring Rule (in the Wiring Config field) defines the terminal configurations of the Field Device, users can select a different configurations clicking on the button in the Tag No field and selecting from the list of configurations in the Select a Field Device Terminal Configuration window that is then displayed. See Select a Field Device Terminal Configuration.

Loop Dwg Code

The 'Loop Code' is used by AVEVA Instrumentation Datalinks to map information into a loop drawing template when generating CAD drawings. It is ONLY required if CAD loop drawings are to be generated in Designer. This 'Loop Code' must be unique for the current loop for CAD loop drawing creation.

Wiring Config

The name of the Wiring Rule to apply to the tag. Select the rule by clicking the button in the field. The Wiring Rule Definitions window is then displayed (refer to Assign Wiring Rules to Tags for further information). Select the required rule from the list of rules and click OK. The selected rule is then displayed in this field.

Junction Box

This displays the name of the equipment the cable will run to. Clicking on the button in this field will display a window used to Assign a Junction Box.

Note: The maximum number of cables that may be connected to a junction box may (optionally) be specified on the More Information window accessed from the Equipment Layout window. If the application of a wiring rule would result in more than when the maximum number of cables being assigned to it, a message is displayed to inform the user of this.

Terminate

When this checkbox is checked, cores will be terminated at the Junction Box end (on the next available spare terminals). When it is unchecked, cores will not be terminated at the Junction Box end. The cores will need to be terminated manually, using Wiring Manager, by dragging the cable or cores to the desired terminals.

Cable Number

This shows the default cable number as created by the wiring rule or the actual cable number from the AVEVA Instrumentation Cable Schedule (if the cable has been created previously). Enter a new value if required.

Cable Type

This shows the base cable type. It can be changed by selecting the cell command button that appears when the mouse is hovered over this cell. The initial cable type comes from the Wiring Rule catalog cable (if the cable is not yet created) or from the Cable Schedule (if the cable has been created previously). Clicking the cell button displays the Select a Cable from Catalog window allowing a new catalog cable to be selected. Refer to Select Catalog Cable for further information.

Note: The core sequences of Wiring Rules override those of catalog cables. The connection order of a Wiring Rule is always preserved even if this does not match the core sequence order defined in the Cable Catalog.

Cable Length

Enter a Cable Length here. This length is saved in Wiring Manager's Cable Schedule.
