- Last UpdatedOct 29, 2025
- 2 minute read
In the Loop Edit window (refer to), click the Create Loop Wiring button. The Create Loop Wiring window is then displayed:
This window lists all the instruments assigned to the current loop.
|
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 Engineer). |
Note: Although the Wiring Rule (Wiring Config) defines the terminal arrangement of the Field Device a different type can be selected by clicking the button in Tag No cell that appears when the mouse hover over this cell.
|
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. |
|
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 AVEVA Instrumentation 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 Wiring Manager's 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 catalogue 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 Catalogue Cable window allowing a new catalogue cable to be selected. |
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 you to pre-assign junction boxes etc. prior to cable/device creation. |
|
Cancel |
Exits the window, not saving or creating wiring. |
Note: Wiring Manager allows limited editing of the predefined Wiring Rules. Limitations are that only Cable No, Wire No, Terminal Marking and Cable Types can be changed.
