Data collection and file storage timing
Collects and stores data to a specified bit device leading edgelfalling
edge, at the sampling interval (every 0.1 to 3600 sec), or at a specified
time.
I
(3) Storage target of collected data
Data collected using the logging report is stored to a file area in the
memory card (RAM type) installed in the AD57G.
The collected data is stored to the corresponding file in the memory card.
When the logging report function is used,
a RAM-type memory card is necessary.

The capacity of a report data file depends on the collection freq. set in
the set report parameter and the logging data set for each report canvas
screen.
The capacity of a report data file can be estimated as shown below:

How to print out data stored to a file
Print out the data in a report canvas format by satisfying the printing
trigger condition set in the AD57GP set report parameter.
After printing has started, the printout cannot be interrupted.
If the printer is not connected, a time out occurs about 30 seconds after
the operation starts.

(In the meantime, other monitoring continues.)
The occurrence of the time out can be confirmed by using the AD57G
system/system alert screen (see Section 6.8).
However, if the PC CPU is not equipped with a clock function,
"00"
appears in the place where the time would be printed out.

How to delete data stored to the file
Data can be deleted by satisfying the data delete timing condition set in
the AD57GP set report parameter.
(The file remains unchanged.)
