The options on this tab allow you to define HART instrumentation properties and create virtual tags for the current instrument. Note that this tab is available only for HART instruments.
If you are creating or editing items that have to be compatible with Emerson DeltaV, see Crucial Fields for the DeltaV Interface.
Tag number
Displays the name of the current tag number.
Segment name
Displays the name of the associated segment.
Analog signal parameter
Allows you to select an appropriate analog signal parameter for the current instrument.
HART instrument properties
The options in this group box allow you to define HART instrument properties of new or existing tag numbers. Also, allows you to add new virtual tags to the current HART instrument. Note that all the properties in this group box are optional.
The SmartPlant Instrumentation Calibration module supports only conventional analog
signals for HART instruments. Digital signals for HART are not supported.
Fieldbus tag name
Not available for HART instruments.
Fieldbus device address
Not available for HART instruments.
Device identification
Not available for HART instruments.
Signal type
Allows you to select an appropriate signal type. Select 
if the value you need is not on the list.
Linearity type
Allows you to select a linearity type. Select if the value you need is not on the list.
Standard
Not available for HART instruments.
Fieldbus device revision
Not available for HART instruments.
DC consumption
Allows you to enter the current consumption in milliamperes.
Capacitance
Allows you to enter a capacitance value and select the appropriate unit of measure.
Minimum transmit level
Allows you to enter the minimum transmit level in volts. This is the minimum signal voltage in volts that is expected at the host port terminals.
Operating voltage
Allows you to enter the minimum and maximum operating voltage in volts.
Virtual tags
Displays the existing virtual tags for the current HART instrument. Also, allows you to create new virtual tags and edit the properties of a virtual tag you select in the data window.
Data Window
Displays the virtual tags and their properties.
Name
Displays the name of a virtual tag.
Digital Signal Parameter
Displays the digital signal parameter of a virtual tag.
Service
Displays the service of a virtual tag.
New
Opens the New Virtual HART Tag Number dialog that allows you to create a new virtual tag for the current HART instrument. Note that if the system I/O type of the current HART instrument is HART AI, the New button becomes available only after you select an analog signal parameter.
Delete
Allows you to delete a virtual tag that you select in the data window.
Properties
Allows you edit the properties of a virtual tag that you select in the data window.
