Assign Instrument Tags to Loops

Instrument Tags can be assigned to loops from the Instrument List.

Note: It is not mandatory for each Instrument tag to be assigned to a loop. For example field pressure gauges and pressure relief valves are not normally members of a control loop. They are stand-alone Instruments.

1. Hover the mouse over the Loop No cell for the Instrument, and a command button appears as shown below:

   

2. If the button is clicked for a tag not currently assigned to a loop, the Assign Tag to Loop... window is displayed.

   

   The Assign Tag to Loop... window shows all loops already defined in AVEVA Instrumentation for the current Project.

3. The list by default is filtered by the current Instrument’s Plant Area number. Select a different are area or "All" if required from the Display by Area list.

4. The Match Number checkbox filters the list of loops by the Tag No. 'number' field. In the example above, selecting Match Number would limit the list of loops to only those containing '510' (the current Instrument is numbered '510').

5. To assign the current Instrument to an existing loop, double-click on the desired loop number in the list of loops, or select a Loop and click the Assign command button.

6. To assign the current Instrument to a new loop, click New Loop button to display the Add New Loop window, refer to Add a Loop to the Loop List. Enter the loop details in the window and save the new loop.

   AVEVA Instrumentation will return to the Assign Tag to Loop... window, in which the new loop will now be listed. You can then assign the current Instrument to the new loop.
