Assign Tags to Loops

In the Edit Loop window (refer to Loop Data), click Add Tag to display the Add Instruments to Loop window.

• The left hand list shows typical tags and descriptions for the Engineer's ISA tag catalogue built using the current Loop function prefix in the Edit Loop window.

• The right-hand list shows all tags assigned to the current loop (if any).

To assign a tag to the current loop use one of the two following methods:

• Build a Tag Number using the ISA tag catalogue (left list) by double-clicking on the required tag and the full tag number is added to the right-hand list.

  Note: If the tag being built does not exist in Engineer's Instrument List it will be added. If it does exist, AVEVA Instrumentation will reassign the tag to the current loop.

• Pick an existing tag number from the Instrument List by clicking the From Instrument List button, which displays the Select Instrument to add to Loop window, used for selecting tags not assigned to any loop. See Select Existing Tags for further details.
