Data is collected every time the designated bit turns ON.
Execution Condition
Select the sampling action execution condition. Select [Bit
ON].
Sampling Trigger Bit Address
Select the address which will control the sampling's timing. The
sampling will execute every time this address turns ON.
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.
Data Full Bit Address
After all the sampling is completed (the set [Occurrences] *
[Blocks]) this address will be used to confirm that the operation
is finished. Select whether or not to verify this bit 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
operation will continue running even when this bit is ON. If not
designated, the sampling action will end when this bit turns ON.
Please turn ON 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.
ACK Bit Address
Select the address which will confirm when the data reading is
finished. When the data reading is finished, the display unit will
turn this bit ON.
When this address receives a [Bit ON] state, please turn OFF the
device/PLC [Sampling Trigger Bit Address]. When the [Sampling
Trigger Bit Address] turns OFF, this bit will turn OFF.
Extended
Displays the [Extended] dialog box.
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.
When this is selected, sampling will continue even after the
number of times has completed. Old data will not remain.
If this is not set, previous data will not be overwritten. The
new rounds of data will be stored as separate blocks. After data
from ([Occurrences] x [Blocks]) has been stored, sampling will not
occur until all stored data has been deleted.
Blocks
All the data collected in the sampled in the designated number
of times is called a [block]. Designate the number of blocks to set
inside one sampling group, only if [Overwrite old data after
finishing the specified cycles] is not set. 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 number
of times) 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
Select whether or not to store the time when the data read
finished, along with the sampled data. If this is not designated,
when displaying/saving in CSV or printing, the date/time columns
will be blank.
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.
