Create Loop Wiring using Wiring Rules

Select

Only those instruments that have their Select checkbox checked are processed when the Create command is used.

TagNo

The instrument tag number - non-editable (tags can only be assigned to a loop using Instrumentation Engineer).

Note:
Although the specified Wiring Rule (in the Wiring Config field) defines the terminal configurations of a Field Device, Users can select a different configurations clicking on the button in the TagNo 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.

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.

WiringRule

The name of the Wiring Rule to apply to the tag. Select the required rule from the list of available rules (the list is only displayed when the mouse is hovered over the cell).

Junction Box

This displays the name of the equipment the cable will run to. A button is displayed when the mouse is hovered of this cell. Clicking on that button will display a window used to assign a junction box. For further information, see Assign a Junction Box.

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 No.

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

Length

Enter a Cable Length here. This length is saved in the Instrument Wiring Manager Cable Schedule.

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 Instrument Wiring Manager Select a Cable from Catalog window allowing a new catalog cable to be selected.

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.

Command Buttons:

Create

Creates all selected tags, cables, termination and other wiring data from the Wiring Rules and data in this grid.

Save

Saves the changed data in the grid, but does not create Wiring Rule data. This enables Users to pre-assign junction boxes etc. prior to cable/device creation.

Cancel

Exits the window, not saving or creating wiring.

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 Instrument Wiring Manager, by dragging the cable or cores to the desired terminals.
