Instrument Data

Designer provides access to the Instrument Engineering data normally created by the Instrument Engineer module.

1. Open the Edit window for instruments by accessing it from the Loop Edit window (refer to Loop Data).

2. In the Loop Edit window, double-click on any tag listed in the Loop Instruments list.

   The Edit window for instruments is then displayed. For example:

   

3. The two important fields for loop drawing generation are found on the Detail tab:

   

   • Wiring Config - this applies the selected Wiring Rules to the instrument. Refer to Wiring Rules Overview.

   • Loop Dwg Code - this is the code number used when Designer creates Datalinks. In the example above the Loop Dwg Code is 1 meaning that all tag Datalinks will be created prefixed '{TAG1'. If the code was 51 then all Datalinks would be created prefixed '{TAG51' This field is only used for generation of Datalinks used to create loop drawings from templates.

     Note: AVEVA Instrumentation recommends using the same Loop Dwg Code for each instrument type. For example, always use 10 for transmitters, 50 for Control Valves etc. This means the Datalinks users embed into the CAD symbols can be copied without to much thought since it is likely that users will use the same CAD symbol for each transmitter, control valve etc.

4. Click on this link to view information on Edit Tag Details - Tabs.

5. Many field options have a user definable PickList associated. Clicking on the # command button next to a combo box displays the PickList Management window.

6. The Last Edit field displays the date and time when the instrument data was last edited. The user name of the individual that performed the edit is displayed in a tool-tip when the mouse cursor is hovered over the field. Click the button in the field to display the Audit Manager, which will display a list of all the changes to the instrument data.
