Used in conjunction with the Archive option, the Max Number of Archive Files allows only the
specified number of archived log files to exist on the System 5000
™
. Once the limit has been
reached, the oldest log file is removed and the process continues. This enables the system to
properly guard its internal memory as well as manage the potentially numerous log file
generation.
The Estimated File Size calculates the approximate amount of space the current log file will fill
over the space of a year. The Estimated Days to Fill Memory takes into account all current Log
Files and the amount of free space currently on the system.
GOES
Adding Tasks to a GOES setup can either be
done through the Add Output selection screen of an existing Task or through the System Setup
- Communications > GOES Configuration screen. The following sections will cover all aspects of
the GOES setup, with special consideration given to the Add Output screen options. The GOES
Configuration, as it is directly accessible from the GOES Output Properties screens, is explained in
full detail in this section as well.
From the Add Output screen, the GOES Self-Timed and GOES Random options are available.
Both GOES Output Properties screens are very similar. Adding Tasks to GOES transmissions
(whether Self-Timed or Random) is done within the respective Output Properties screens.
The rate of each GOES Self-Timed Output directly affects how much data will be sent with each
transmission. For example, if transmissions are scheduled for every hour, having an Output Rate
of 15 minutes (00:15:00) will allow the past four values (60/15 = 4) to be sent each transmission.
Changing the Output Rate to every 5 minutes (00:05:00) would allow the past 12 values (60/5 =
12). In the above screen, through the Task is scanning every minute (indicated by the Input
Rate), a much slower Timed Rate (such as 15 minutes) would be preferable to fit within the
allowed GOES transmit buffer. Timed Rates should always be a multiple of the Input Scan Rate.
The GOES Radio is capable of sending
data at regular timed intervals called
Timed Transmissions or Self Timed Mode,
and at random intervals called Random
Transmissions or Random Mode. Both
types of transmissions can be in operation
at the same time. The System 5000
™
will
check if data is to be sent to the GOES
Radio data buffer after each scan interval.
If data is in the GOES Radio timed data
buffer, it will be transmitted at its normal
interval. Data in the random buffer will be
transmitted at a random time based on the
random transmit window.
