Structuring the Tag (.CSV) Import/Export File Format 8-5
The following examples show ALIAS records.
Specifying a
Comment Record
Each COMMENT record defines a comment about a component of a
TAG record. A COMMENT record follows this format:
COMMENT,”Scope”,”Name”,”Description”,”Datatype”,”Specifier”
The following examples show COMMENT records.
Example: Description:
ALIAS,,hot,””,””,”temp” There is no scope specified, so this is a controller scoped tag.
The alias tag is named hot.
There is no description.
There is no datatype for an alias, it is the same as the base tag.
The specifier is the name of the base tag.
ALIAS,recipe_b,start_value,”have this much at first”,””,”int_a” This tag is program-scoped to the program named recipe_b.
The alias tag is names start_value.
The description is “have this much at first.”
There is no datatype for an alias, it is the same as the base tag.
The specifier is the name of the base tag.
Example: Description:
COMMENT,,timer_1,”this is the enable bit”,,”timer_1.en” There is no scope specified, so this is a controller scoped tag.
The comment is associated with the tag “timer_1”.
The description is “this is the enable bit”.
There is no datatype for a comment.
The specifier is the tag member associated with the comment.
COMMENT,,ratio,”this is the bit to monitor”,,”ratio.3” There is no scope specified, so this is a controller scoped tag.
The comment is associated with the tag “ratio”.
The description is “this is the bit to monitor.”
There is no datatype for a comment.
The specifier is the bit associated with the comment.
COMMENT,recipe_b,table,”look at this element”,,”table[8]” This tag is program-scoped to the program named recipe_b.
The comment is associated with the tag “table”.
The description is “look at this element.”
There is no datatype for a comment.
The specifier is the element of the array associated with the comment.
COMMENT,,mask_1,”use this mask value”,,”” There is no scope specified, so this is a controller scoped tag.
The comment is associated with the tag “mask_1”.
The description is “use this mask value.”
There is no datatype for a comment.
There is no specifier because this specifies a description of a tag, not a
component of a tag.
Important: If you use the COMMENT statement for a tag, it overwrites
the description part of the TAG statement for that tag. The COMMENT
tag essentially defines a new description for the tag.
