Definition |
An expression containing point identifiers, constants, and either arithmetic or logical operators. The expression may be up to 78 characters in length. |
Note: If another Point ID is used in
the expression, it must be in the recognized format, or else the
Point ID must be enclosed in single quotation marks – for example,
'1 - this is a
point_id'. The recognized format is an alphabetic
first character followed by alphanumeric characters and/or an
underscore. If a Point ID contains embedded blanks or
non-alphanumeric characters (other than underscore) or does not
begin with a letter, its format is not standard.
