When you prepare a Smart Instrumentation domain for publishing to DeltaV, you must be careful to enter values with limitations according to the table that follows. In most cases, the software validates the data; however, it does not validate data that you merge in the database or data that you enter via an EDE view; in these cases, it is up to you to check that the values comply with these limitations.
-
Smart Instrumentation validates the data only if the DCS manufacturer name is Emerson Process.
-
If you intend to publish fieldbus data, set the relevant option on the Preferences dialog. For details, see Interfaces > DCS Vendors (Preferences).
-
Spaces are not allowed in DeltaV tags, therefore, when publishing data, Smart Instrumentation removes spaces in instrument and Control System tags. You can specify a substitute character, such as an underscore, to replace the spaces; to do so, you must add the following line in the Intools.ini file under the [API] section:
NameSpacesReplacement = "_"
It is recommended not to select any character that appears in the tag names as the substitute character because when retrieving data back from DeltaV, Smart Instrumentation replaces that character with spaces again.
Item Type |
Limitation |
---|---|
I/O Card |
The DCS manufacturer name is Emerson Process and this must not be modified. |
I/O Card |
The card name must begin with an uppercase 'C' followed by a numeric value, for example C16. |
Rack |
The rack name must be a numeric value. |
Slot |
The slot name must be a numeric value between 1 and 8 characters. |
Controller |
The controller name must be unique in the domain. |
Controller |
The controller name must be uppercase and between 1 and 16 characters. |
Units of Measure Limitations
To avoid errors when publishing data, only those units of measure that are supported by DeltaV should be available for selection. To set the available units of measure, select Tools > Units of Measure Codes, and clear the Enabled check boxes for all units of measure except for those that appear in the following table.
