Measured plant data in various forms are transferred to PRO/II through text files. Reconciled data files created by DATACON have .ADJ extensions, whereas unreconciled data files may have .RAW, .TDF, or .DAT extensions. The Tag Data file may be created using a text editor, or it may be generated by plant control-system software. See Import Tag Data for more details.
You may enter the date that the data were measured as the first line in the file. This entry is optional but it is strongly recommended. This line will have the keyword DATE followed by an integer number of up to 8 digits. You may use any format that is clear to you. For example, 02082001 would be 2nd August 2001 or you could have 08021030 for 10:30 am on 2nd August.
The subsequent lines of the file contain the measured variables - each on a separate line in the format:
tagid value
The tagid is a unique identifier of up to 12 characters. Value is the measured value in integer, floating-point or scientific (E) format.
Comments may be inserted in the file after a dollar sign ($) character, and blank lines may be entered.
