When using external storage, verify the restrictions identified below.5.6.3 Restrictions on External Storage Usage
Only one Special Data Display [Show CSV] can be placed per screen.
When you place a Special Data Display [Show CSV] on a Window Screen, you cannot edit the data. (The editing screen cannot be triggered.)
Do not draw a Special Data Display [Show CSV] on the same screen as a Sampling Data Display with [Edit Data] selected or a Data Display with [Allow Input] selected.
You cannot update CSV data by transferring from the device/PLC to the external storage device, while the CSV data is being edited. A write error is written to the [Status Address].
If the cover of the CF Card slot is open or the external storage device is removed while CSV data is displayed, the display is cleared.
If the screen changes while CSV data is displayed, the display is cleared.
There are two valid data formats for CSV data displayed in a Special Data Display [Show CSV]. Data separated by commas [,]. And data in double quotation marks [""], separated by commas [,].
For example, CSV format (Sampling data)
Special Data Display [Show CSV] does not support the multiple line display. Data containing line feed will not be displayed correctly.
Only one Special Data Display [File Manager] can be placed per Base Screen. It cannot be placed on a Window Screen.
The Special Data Display [File Manager] cannot be scaled up or down.
When using the GP3000 Series, LT3000 Series, or ST3000 Series, set both the X-coordinate of the position of the Special Data Display [File Manager] and the width of the Special Data Display [File Manager] in 4-pixel increments. If not set properly to 4-pixel increments, the position is automatically adjusted to 4-pixel increments.
You can display the Special Data Display [File Manager] part using a Special or Local Window. If the maximum number of windows are already displayed, the File Manager does not appear. Close other windows to display the [File Manager] display part. 12.9 Displaying Multiple Windows on a Single Screen
When a text table changes, the Special Data Display - File Manager is closed.
If there is more than one display switch for a Special Data Display [File Manager], and if you touch another display switch while a File Manager is already displayed, the [File Manager] window that is currently displayed closes.
Files currently displayed on a Special Data Display - Show CSV cannot be deleted with a Special Data Display [File Manager].
If a full path (a folder name and a file name) exceeds 99 characters, files or folders may not be displayed correctly in the Special Data Display [File Manager].
If a file name or folder name contains a character after ASCII code 0x80, files or folders may not be displayed correctly in the Special Data Display [File Manager].
The Special Data Display [File Manager] display depends on the [System Settings], [Display Unit], [Display Settings] tab's [System Language] setting. Depending on the language, file names or folder names may not appear correctly. An error occurs if you transfer a file to a folder that is not displayed correctly or if you try to perform a file operation in that folder.
When using the IPC Series or SP5000 Series Open Box, the file manager list display will automatically revert back to the root folder or specified default path if the contents of the folder or file displayed in the file manager is updated.
Editing Restrictions
The editing screen for a Special Data Display [Show CSV] displays via a Special or Local Window. If the maximum number of windows are already displayed, the editing screen cannot be activated. Close another window before editing the data.12.9 Displaying Multiple Windows on a Single Screen
On the same screen, do not draw a Special Data Display [Show CSV] with [Edit Data] selected and a Historical Trend Graph with [Selected Time]. When drawn on the same screen, only the first drawn part will work.
You can edit up to 56 characters in a Special Data Display [CSV Display]. This limit depends on the model and orientation.
You cannot update CSV data by transferring from the device/PLC to the external storage device, while the CSV data is being edited. A write error is saved to the [Status Address].
When a text table changes, the editing screen will be automatically closed.
Even when the [Interlock Address] state matches the [Touch Enable Condition] during editing, editing can be performed. However, if editing is attempted again, the screen will not enter Edit mode because the Interlock feature is enabled.
Numeric values displayed on a Special Data Display [Show CSV] are displayed as text. Therefore, the inputs are edited regardless of properties such as the number of display digits, data length, and data type.
Special Data Display [Show CSV] does not support a multiple line display. If the data contains a line feed, it will become invalid on editing.
While the edited data is being output to a CSV file, printing and editing modes are disabled. Also, the system cannot be moved to off-line mode.
Regardless of the Show Column settings, the column portion cannot be edited.
When editing data, a temporary file is created on the external storage device. As a result, free space equivalent to the size of the edited file must be available. You cannot edit the file if this capacity is not available.
When editing data, the internal processing updates the file as follows.
For example, when editing "ZR00001.csv"
After pressing the [ENT] key, a temporary file (a file that reflects the editing results), "_CSV$$_0.tmp" is created.
The original file name is changed from "ZR00001.csv" to "_CSV$$_1.tmp"
"_CSV$$_0.tmp" is changed to "ZR00001.csv"
"_CSV$$_1.tmp" is deleted.
If the power turns OFF during editing or if editing fails, temporary files may remain on the external storage.
When a Special Data Display [Show CSV] is rotated by 90 or 180 degrees, the editing screen characters are not displayed properly. To place a rotated [Show CSV], set rotation to 0 or 270 degrees.
Restrictions for Printing
The horizontal lines are not printed.
You can print up to 160 characters per line. Characters that exceed the maximum are not printed.
The number of characters that can be printed on one line depends on the printer and paper size. When the characters in a single line do not fit onto the paper width, the outputted results will differ depending on the font and printer.
Standard Font
When text does not fit the paper width, there are printers that do not print text outside the paper width, printers that automatically insert line breaks to print all text from each line, and printers that do not print properly.
Stroke Font
Text that does not fit the paper width does not print.
Regardless of the Show Column settings, the column portion will not be printed.
When printing only the displayed portion, if the data in the right most cell extends beyond the screen and is cut off on the Show CSV Display, that portion is also cut off on the printout.
While printing, the data cannot be edited or printed. Also, the system cannot be switched to off-line mode.
