Create a HART Instrument - Intergraph Smart Instrumentation - Help

Press F7 to open in the Domain Explorer.

1. Expand the plant hierarchy to display the Instruments and Loops folders.

2. Do one of the following:

   • To create an instrument not associated with a loop number, right-click the Instruments folder, and then select New > Instrument.

   • To create an instrument that is associated with a specific loop number, expand the Loops folder, right-click a loop, and then select New > Instrument.

3. On the New Tag Number dialog, do the following:

   1. From the Tag class list, select HART.

   2. Type the name of the new tag number.

   3. Select OK.

4. On the Select Instrument Type dialog, select the instrument type you want to associate with the current hart instrument, and then, select OK.

5. Select OK.

   

   • Remember that you need to define appropriate instrument type profiles for your HART instruments prior to creating them. These instrument type profiles must include an I/O type which is either HART AI or HART AO. For details, see Define Instrument Type Profiles for HART Instruments.

   • If the tag number does not correspond to an existing loop name, Smart Instrumentation prompts you to enter a loop name based on the tag number you have entered. If the loop identifier already matches an existing loop, the software will automatically associate the new tag number with the loop.

   • If the loop convention includes the loop function parameter, the prompt will always appear. In this case, you have to complete the loop number.
     If a profile exists for the selected instrument type, any new tags for that instrument type will be created with the selected reference items.

   • For DeltaV compatibility, you must select an instrument type that you associated with a DeltaV device type during the downloading process. To display the Associate Foundation Fieldbus Device Types with Instrument Type supporting table of associations that you built among DeltaV device types, instrument manufacturers, and Smart Instrumentation instrument types, see Associate Device Types for DCS Vendors.

6. On the Loop Name dialog, do one of the following:

   • Type the loop number that the new tag is associated with.

   • Accept the displayed loop number.

   • Select Cancel to create the tag number without a loop association. Note that if a loop with the same name exists, the tag number is automatically associated with it, without creating a new loop.

7. Select OK to create the loop number.

8. On the Loop Number Properties dialog, accept the loop number properties or modify them as you require and then select OK.

9. On the Tag Number Properties dialog, on the General tab, enter the tag number attributes that you require.

   For DeltaV compatibility, make sure that the value that you select from the Manufacturer list is among the acceptable values for the instrument type that you selected for the current tag. For details, see Crucial Fields for the DeltaV Interface.

10. To enter power supply properties, see Enter Power Supply Data for Panels and Instrument Tags.

11. Select the HART tab to define the instrument parameters and create virtual digital tags.

12. Select a signal type and linearity type values if needed.

13. From the Analog signal parameter list, select a parameter that is appropriate for the analog signal of the current HART instrument.

    This selection is available only if the I/O type of the current instrument is HART AI.

14. Enter the required DC consumption, capacitance, minimum transmit level, and operating voltage.

15. Create the required virtual digital tags. For details, see Create a Virtual Digital Tag.
