K. DEFINING HIS FUNCTION
the previous day may be specified, and the daily closing time may be
adjusted within the range of 0:00 to 23:00 (in hour units).
♦ Monthly Closing
In the monthly closing process, the daily closing data of the previous one
month are gathered, and the monthly closing data are calculated for the
month, including the average, total, maximum and minimum values. The
calculated monthly data are stored into the monthly data files created for
each trend gathering pen. Monthly closing processing is performed after
the daily closing processing on the last day of each month.
♦ Disk Space Used
Each type of closing data may be saved for the following period:

K.2.4 LONG-TERM DATA SAVE
♦ Historical Message, Hourly Closing, Daily Closing, Monthly Closing.
After trend data, closing data and historical messages are saved using the
HIS standard function, they are automatically stored via the long-term data
archive. The storage period in the long-term archive depends on the data
type and data storage unit defined on the Trend Acquisition Pen
Assignment Builder or on the HIS Constants Builder. When the storage
period is defined, the required total hard disk space is calculated
automatically. So long the 5 % free space is reserved in the hard disk, the
data storage may take as much space as desired.
