CSV File Format
The CSV file is formatted according to these considerations:
- Within each record (that is, each line), each field is separated by a comma
- Each record or component is separated by a carriage return
- The first line in the file contains a version number, followed by a set of component blocks
- Each component block consists of a schema line and a set of records. A schema line is a block separator that indicates the end of the previous block and the beginning of the next block. Any line whose first column is "Type" is interpreted as a schema line.
- Any line whose first column is Remark is ignored by the import process
Note that special characters in the .CSV file may fail to import. The Import Tags command may fail if special characters (for example, =, +, ", ', -) are included in the tag description and the .CSV file was edited using Microsoft Excel software. The .CSV import process requires and verifies that all descriptions adhere to the IEC-61131 Name Standard. The IEC-61131 Name Standard is an identifier that is a string of letters, digits, and underline characters that begin with a letter or underline character. Underlines are significant in identifiers (for example, A_BCD is interpreted differently than AB_CD). Multiple leading or multiple (consecutive) embedded underlines are not allowed, trailing underlines are not allowed, and letter case is not considered significant. (The names are composed per IEC-61131, section 2.1.2.)
TIP:
In
Logix Designer
, most component names are limited in length to 40 characters or less.In the file imported, the sequence "= is not allowed.
Also note that when importing or exporting to a CSV file, Microsoft Excel software can only display Arabic characters. If using an Asian character set, use the .txt format to import or export.
