-
The FTP Server timeout is 75 seconds. An error
will occur if a connection to the FTP Server does not occur within
the timeout period.
The time stamp is applied to the file name.
For example, when the file is saved on 2006/05/27, at 15:23:46, the
filename is CP060527_152346.jpg.
Hard Copy File Number
When taking screen captures, defines the
***** portion of the file name [CP*****.jpg] as a value from 0 to
65535. When [Auto Increment File Number] is used, the file number
is automatically stored in this address.
The file number of the screen-captured file
uses the time stamp and does not refer to the [Control Address]+2
value.
In the file output completion bit, the status
address Bit 1 turns ON when the capture process was completed.
After the capture process is complete, confirm that the file output
completion bit is ON and then turn OFF the file output bit from the
device/PLC. If the file output bit is turned OFF, the display unit
turns OFF the file output completion bit. The timing of the control
and status during capture is as follows.
-
If you turn OFF the file output bit (control)
before the file output completion bit turns ON, the file output
completion bit is automatically turned OFF.
-
If an error occurs while processing screen
capture, the status area is not cleared when the control address
trigger bit is turned OFF. It will be cleared next time the process
is completed successfully.
Reverse Black/White
Specifies whether to save the screen captured on a CF Card in
black and white reverse display.
-
On a monochrome or color model, the black/white
reverse states are displayed as follows.
-
You can reverse only black or only white.
-
Color inversion is not available.
Auto Increment File Number
When a screen is captured, a new file is created with a file
name automatically assigned by adding 1 (numbering) to the highest
number of the existing files. The feature is available when saving
to [CF Card] or [USB Storage].
The automatically numbered file number will be written to
designated [Control Word Address] +2.
Numbering occurs to a maximum of 65535. After that screen
capture will not function. to continue, use [Auto Delete File] or
[Loop].
-
The display unit searches for the highest file
number upon power-up, upon opening o rclosing of the CF Card hatch,
and upon insertion or removal of the CF Card or USB storage.
-
When using this function, file numbers
specified to the designated [Control Word Address] +2 are
ignored.
Auto Delete File
Deletes existing files and allows new files to be saved when the
file number exceeds the maximum of 65535 or the CF Card/USB storage
does not have sufficient free space.
When a file with the maximum file number
exists
If the CF Card/USB storage already has the maximum number
(65535) file, it deletes all the existing files and creates new
files starting with file number 0.
For example, when "CP65535.JPG" exists in the CF Card
All screen capture files in the CF Card "CP*****.JPG" are
deleted, then saves "CP00000.JPG".
When the CF Card/USB does not have
sufficient free space
This feature deletes the file with the lowest file number and
creates a file with the highest file number + 1.
For example, files with file numbers CP00100.JPG to CP00300.JPG
are saved on the CF Card.
The file with the smallest number, "CP00100.JPG", is deleted and
the new file "CP00301.JPG" is created.
Loop
During screen capture, a new file is created with the file
number assigned by adding 1 to the file number with the most recent
time stamp among file numbers in the CF Card/USB storage. 00000
through 65535 exist on the CF Card, the files will be overwritten
sequentially from file Number 00000 and the screen captures will
continue.
The latest file has the maximum file
number
When the latest file number is 65535, a new file is created with
file Number 00000.
For example, files with file numbers "CP65531.JPG" to
"CP65535.JPG" are saved on the CF Card.
A new file, "CP00000.JPG", is created.
When the CF Card/USB does not have
sufficient free space
During screen capture, the oldest file is deleted and the new
file is saved with a file number 1 larger than the latest file.
For example, when the latest file is "CP00000.JPG"
The oldest file, "CP65531.JPG", is deleted and the new file
"CP00001.JPG" is created.
-
When a file is deleted due to insufficient free
space on the CF Card or the USB storage, the oldest file is deleted
in order to create a new file. In such a case, it may take twice as
long to save a file compared to saving when there is sufficient
free space.
FTP server
It is displayed only when you select [FTP Server] for the Save
in location. Select the FTP server number to use. (FTP server
number is the number that you registered in the system settings
[FTP Server Settings].)
Capture Image Quality
Specify the capture image quality from 1 to 100. You can also
specify by directly inputting numeric values.
1: Low-Quality Image, High Compression
100: High Quality Image, Low Compression
