Sample data at constant cycles starting from when the display
unit is turned ON, but only when the designated bit is ON.
Execution Condition
Select the sampling action execution condition. Select [Constant
Cycle when Bit is ON].
Sampling Permit Bit Address
Select the address which will control whether or not sampling
will execute. While this address is ON, data will be read each
cycle.
Sampling Frequency
Frequency
Select the sampling frequency from [Constant] or [Address].
When you select [Address], you can change sampling frequency at
run time.
Sampling Frequency
When [Frequency]=[Constant], specify the sampling frequency at 1
second or 100 milliseconds.
Set 1 to 65535 when the unit is 1 sec and 1 to 9 when the unit
is 100 ms.
When [Frequency]=[Address], specify the sampling frequency with
a word address.
-
You can only set up an internal device
address.
-
Values are read using the decimal (unsigned)
format.
-
If you store a value outside the range
supported by the address, operates as follows.

The value in the specified address is cleared
(0) on the following timing. to avoid clearing to 0, please use the
internal device's backup feature.

-
The defined address is monitored every 50
milliseconds. Checks for changes in value in the specified address
before changing the sampling frequency. As a result, there may be a
delay in changing the sampling frequency. Plus, when the [Sampling
Permit Bit Address] turns ON the sampling frequency changes.
Occurrences
Select the number of times sampling will occur. The setting
range is from 1 to 65535.
Data Full Bit Address
After the designated number of data samples are completed, this
address will be used to confirm that the operation is finished.
Select whether or not to verify this bit address.
This bit tells when a data sampling cycle is complete. The
sampling operation will continue running even when this bit is
ON.
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.
Overwrite old data after finishing the
specified cycles
Data will be overwritten and stored, starting with the oldest
data, after data has been sampled the designated number of times.
This setting is fixed to enable.
Add Time Data
Select whether or not to store the sample time along with the
sampled data. If this is not designated, when displaying/saving in
CSV or printing, the date/time columns will be blank.
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.
