Disk Space Analysis
AnaWin examines your hard drive and displays the amount of disk
space available for data storage and how many days of data can be
collected based on current hard disk space for current recording rate.
Recording Rate
Use the Recording Rate field to specify how frequently data is collected
for defining data points on the plot screen. The number of seconds you
enter here will directly affect how much disk space is required. For
instance, one day of data saved at a recording rate of 5 seconds requires
twice as much disk space as it would at a recording rate of 10 seconds.
Maximum Days Stored on Disk
Use the Maximum Days Stored on Disk field to set the number of days
of historical data collected for plotting. AnaWin does not maintain trend
plot data indefinitely, but you can save data for any number of days
allowed (as determined by available disk space). The available disk
space will also be impacted by the recording rate, as described above.
NOTE
If you wish to preserve data indefinitely, you can export the data
using the Export Database option from the File menu. If you antic-
ipate the need to store data for a long period of time, you can enable
the Data Logging feature by selecting Data Log Setup from the File
menu.
