1.3 Data Management Limits

Data are stored in the following directories:
• Workpieces
• Part programs
• Subroutines
• User cycles
• Standard cycles
• Manufacturer cycles
The data management directories can contain a combined total of 100,000 files,
whereby each directory (each *.WPD workpiece directory for workpieces) is limited
to 1,000 files. Files in other directories do not count toward the total limit of 100,000
files. However, each of these directories is also limited to 1000 files, e.g., a
maximum of 1000 archives in the archive directory. The following limit applies to
network drives: maximum of 1,000 files per directory.
In practice, the number of files available also depends on the file sizes and the
available memory space. A large number of files slows down the display generation
for directory displays.
A total of 5,000 customized alarms/messages can be created in each language

1.4 Protection Level Concept

Overview
A protection level concept for enabling data areas is implemented in SINUMERIK
840D. Protection levels 0 to 7 are available, where 0 represents the highest
protection level and 7 the lowest protection level.
Protection levels
•
0 to 3 are locked by means of a password
•
4 to 7 are locked by means of keyswitch positions
The operator only has access to information corresponding to this particular
protection level and the levels below it. Machine data are routinely assigned
different protection levels.
Protection level 4 (keyswitch position 3) is the minimum level required to display
machine data. For system startup, the appropriate protection level can generally be
enabled by entering the password "SUNRISE".
