String Operators in Import Links - Intergraph Smart Instrumentation - Help

'...'

Single quotes. You must enclose any fixed string in single quotes if you do not want to link the source data directly.

'101-FT-100' — Imports a specific tag number.

(n,n)

Sub-string operator. This operator allows you to transfer a sub-string of a source field value by adding in parentheses the string parameters: the starting character and the string length.

cab_name (3,2) — Indicates that you want to transfer two characters from the cab_name field, starting from the third character.

&

Ampersand character. This character allows you to trim any leading or trailing spaces in the imported value. You must add the & character before the field value in the link.

&tag_name (5,5) — In this example, the source field (tag_name) is a string representing an entire tag name such as 101-FT -100 (where the instrument type segment can be up to 5 characters long and includes trailing spaces). This example includes a sub-string of 5 characters in length starting from the 5th character, which in this case is 'FT ' (with 3 trailing spaces). The '&' character preceding the string ensures that these trailing spaces are trimmed, so that the imported string will be 'FT'.

#

Pound character. The # character, preceded and followed by a + character (...+#+...) indicates the end of the current line so that the imported value following #+ appears on the next line.

spec_note1+#+spec_note2 — Imports two spec note from a predefined source fields and displays the second note on a new line.
