The following is a suggested flow of activities for HART instrumentation in Smart Instrumentation. Note that you can carry out some of the procedures in a different order, depending on your preferences or requirements.
-
Define the appropriate instrument types for HART instruments. When defining the profile for HART instrument types you must select HART AI or HART AO as the I/O type. For more information, see Define Instrument Type Profiles for HART Instruments.
-
Create your HART instruments. HART instruments can be HART transmitters, HART IP converters, and so on. For details, see Create a HART Instrument.
-
Create a virtual digital tag. Each HART instrument has a different set of digital signals. The digital signals depend on the I/O type (AI or AO) and on the instrument manufacturer who supplies the HART instruments with a specified variety of possible digital signals. For more information, see Create a Virtual Digital Tag.
-
Create I/O cards compatible with HART instruments. For details, see Create an I/O Card Compatible with HART Instruments.
-
Connect the HART instruments to the appropriate HART I/O cards. You make this connection by right-clicking an I/O card in the Domain Explorer and then selecting Actions > Connection.
-
Effect I/O assignment for HART instruments. For details, see Effect I/O Assignment for HART Instruments.
