12 Documentation
The sequence controller AST11 provides a wide variety of documentation possibilities.
12.1 Final values
If the command 'save value' is used on the screwing program, then the screwing results
are stored in a CSV data and can be loaded by the sequence controller via the web inter-
face (see also 8.3.4.7 Process Data Final ValuesProcess Data ). The command
"save values" can be used as often as you like within the screwing process, however, only
the three last values are saved. In case of a fault these values are always saved.
IMPORTANT
The data is only available if the screwing program has received the com-
mand "save final values" or if a faulty screwing application is present.
One CSV data per day is saved. The last data of the last seven days is always available.
The final values of the screwing application that are older than seven days are overwritten
by new final values.
The final value data of the last screwing application are also saved in the file "actual.csv".
The files are subject to the same limitations as described in chapter 12.2 Curve Represen-
tation for the curve data.
The CSV file is structured as follows:
• First line: Title bar with caption of the values
• Following line: results of a screwing application per line
