Sample data at constant cycles starting from the designated
time.
Execution Condition
Select the sampling action execution condition. Select [Set
Time].
Sampling Permit Bit Address
Select the address which will control whether or not sampling
will execute. When this address is ON, sampling will begin at the
designated [Start Time], and after that, read in data at each cycle
of the set [Sampling Cycle].
When this address is OFF, sampling will not occur even when the
[Start Time] is reached.
Start Time
Designate the sampling action's start time. Set the time from 0
to 23 (hour), and 0 to 59 (minute).
Sampling Frequency
Set the period that sampling will occur in 15-second increments
from 0 sec. to 23 hours, 59 minutes, 45 sec.
Occurrences
Select the number of times sampling will occur. If in the
[Extended] area the [Overwrite old data after finishing the
specified cycles] check box is selected, this can be from 1 to
65535 times. If the check box is cleared, the range is from 1 to
2048 times.
End Time
Set the [Start Time], [Sampling Cycle], [Occurrences], and the
sampling end time will be displayed.
Data Full Bit Address
After all the sampling is completed (after the designated
[Occurrences] * [Blocks], or [Occurrences] * [Number of Days]) this
bit address will turn ON to confirm that the operation is finished.
to confirm, set this address.
In the Extended area, when the [Overwrite old data after
finishing the specified cycles] check box is selected, this bit
tells when a data sampling cycle has been done. The sampling action
will continue running even when this bit is ON.
If not designated, the sampling action will end when this bit
turns ON. Please turn OFF the [Data Clear Bit Address] to
resume.
Data Clear Bit Address
Designate the bit address to control the clearing of the
sampling data. When this address turns ON, all the Sampling Group
data stored in the display unit will be erased. After clearing the
data, this bit will turn OFF.
Extended
Displays the [Extended] dialog box.
The contents is different depending on whether the [Overwrite
old data after finishing the specified cycles] check box is
selected or cleared.
Overwrite old data after finishing the
specified cycles
Select whether or not the data will be overwritten and stored,
starting with the oldest data, after data has been sampled the
designated number of times.
If this is set, even when all the data sampling has completed
([Occurrences] x [Number of Days]), sampling will continue and
data, starting with old data, will be overwritten.
If this is not set, previous data will not be overwritten. The
new rounds of data will be stored as separate blocks. After all
data has been stored ([Occurrences] x [Blocks]), sampling will not
occur until all stored data has been deleted.
Number of Days
Set the number of days of sampling data that will be maintained
in the display unit. Data from the designated number of days is
stored, and then overwritten in order, starting with data on the
first day. The setting range is from 1 to 2048. The setting range
is limited to ensure that the amount of [Occurrences] x [Number of
Days] is 65535 or less.
Blocks
The complete set of data collected in the designated number of
times is called a [block]. Designate the number of blocks to set
inside one Sampling Group. The setting range is from 1 to 2048.
The settings range is limited to ensure that the amount of
[Occurrences] x [Blocks] is less than 65535.
Block Completed Bit Address
After the sampling for one block of data (the designated
Occurrences) is completed, this bit address will turn ON to confirm
that the operation is finished. to confirm, set this address.
This tells that one block's sampling has completed. The sampling
action will still continue for the designated [Blocks].
Add Time Data
The sample time will be stored along with the sampled data. This
setting is fixed to enable.
Add Data Valid/Invalid Flag
Stores an observation flag along with the data which monitors if
the data has been saved properly. This setting is fixed to
enable.
Retain Sampling Data (SRAM)
Select whether or not to save the sampling data to the backup
memory (SRAM). If the sampling data is not saved, the data will be
deleted when the power to the display unit is turned OFF or
reset.
Back Up Sampling Data
Indicates whether data saved in the backup memory (SRAM) is
written to the location specified in [Save in]. The data is saved
in binary format.
25.11.1 Usage Capacity of Sampled
Data
Save in
Select the "Save in" location of the backup data, from [CF card]
and [USB storage].
Folders are automatically created for each sampling group in the
"Save in" location. The saved file name will be Time Stamp
(year/month/day/hour/minute/second when saved).
For example, when it is saved at 14:30:5 on July 2 in 2007
\SAMP**\T070702_143005#.bin
("**" represents sampling group number and "#" represents index
number)
Backup Count
Specify the number of times (1 to 500) to write the backup data.
The number specified here is the number of files that will be
created.
When Exceeding Backup Count
Select an action when the number of backup files exceeds the
value set in the Backup Count.
Delete the oldest file and add a new
file.
Stops backup. "1001" (number of files
exceeded) is stored in the status address.
Status Address
Indicates whether the saved operation status and error
information are stored in the specified address.
The error status indicates the following error codes.

Even if the error status is saved, retains the
save request. The save process runs the moment the error status is
released. If the [Data Full Bit Address] turns ON while still in
error status, the retained save request is discarded, and the save
request for the new backup data is now retained.
