This option allows you to change the instrument type and process function of an instrument tag. You make this change when editing instrument tag number, this can be done in single or multi-mode.

1. Open the Tag Number Properties dialog.

2. On the Tag Number Properties dialog, from the Instrument type list, select the instrument type that you require.

   OR

   Select to open the Instrument Type dialog, where you can modify the existing instrument types or add a new instrument type to the list.

3. On the Tag Number Properties dialog, select Apply.

   Instead of selecting Apply, you can select Rename to rename the current tag number as required.

4. If the selected instrument type belongs to a different process function, in the Tag Number Renaming Options dialog do one of the following:

   • Select Keep general process data to delete only specific process data associated with the tag whose instrument type you are changing.

   • Select Delete process data to delete all the process data associated with the tag whose instrument type you are changing.

5. If you want to rename the associated control system tags, do the following:

   1. Select the Rename CS tag check box.

   2. On the New Control System Tag data field, modify the control system tag name as required.

   3. Select OK, to return to the Tag Number Properties dialog.

• If you have connected several CS tags to the current tag number, the system automatically assigns the same new name to all the CS tags. You must rename the new CS tags manually to make the names unique.

• Before selecting OK, note that all the wiring items that were associated with the old CS tag will be renamed according to the new control system tag name, and the associated specification will be deleted. Verify whether the appropriate loop blocks and hook-ups are associated with the new tag number.
