7.3.2.2
Fill-and-Stop Mode
The following program outputs a sample of the panel temperature to the card once
a second. The first parameter of the
CardOut()
instruction is 1, which sets the
table on the card to fill-and-stop mode. The second parameter (1000) is the
number of records which will be written before the table is full and data storage
stops. Once 1000 records have been stored, data storage to the specified table on
CRD: and CPU: datalogger memory drives will stop.

To restart data storage to the fill-and-stop table, the table must be reset.
To reset a table after a fill-and-stop table has been filled and stopped, either use
the reset button in LoggerNet (LN Connect | Datalogger | Station Status | Table
Fill Times, Reset Tables) or use the CRBasic
ResetTable()
instruction.
7.3.2.3
Mixed Modes
The following program stores four data tables to the card. The first two tables will
output samples of the panel temperature and battery voltage to the card once a
second. The first parameter of the
CardOut()
instruction is 1, which sets the
tables on the card to fill-and-stop mode. The second parameter is 1000, so 1000
records will be written to each table before stopping.
Tables 3 and 4 will output the maximum and minimum of the panel temperature
and battery voltage to the card every five seconds. (The tables will be called once
a second. The
DataInterval()
instruction causes data to only be stored every five
seconds.) The first parameter of the
CardOut()
instruction is 0, which sets the
tables on the card to ring mode. The second parameter is negative, so all available
memory on the card will be allocated to these tables, once space for the fixed-size
tables has been allocated. The datalogger will attempt to size the tables so that
both will be full at the same time.
