reference) differs depending on the display unit model.
1.5 Supported
Features
-
External storage you can use to save data in (or
reference) differs depending on the function.
5.6 Usable External Storage
-
While data is written to external storage,
changes in the display of parts and screens may slow down.
-
It may take several seconds to write data,
depending on the amount.
-
After the Status data is read from the display
unit, be sure to allow time equal to at least one communication
cycle*1 or one Display Scan Time
period*2, whichever is longer,
before the next command can be written.
-
When external storage is not attached to the
display unit, do not run screens that use external storage. It may
not work properly.
-
If a write error occurs, any file that has not
finished writing may remain on the external storage.
-
When overwriting, the required available space on
the external storage is more than the size of the actual data. If
the data is larger than the available space, a write error will
occur.
-
The display unit cannot detect NTFS formatted
external storage. Format the external storage using FAT or FAT32 on
your computer.
-
When saving data to external storage, the folder
(such as "\alarm") is automatically created if it does not already
exist. However, if external storage is not formatted properly, a
write error will occur as the folder cannot be created.
-
Please connect only one USB storage device to the
display unit. Even if multiple USB storage devices are connected to
the display unit, you can only use the USB storage that is first
recognized.
-
The display unit can use USB storage devices with
a maximum capacity of 2 GB.
-
Use a CF Card manufactured by Digital Electronics
Corporation (Pro-face). If a CF Card manufactured by another
company is used, the contents of the CF Card may be damaged.
-
The number of times that data can be written on a
CF Card is limited. (Approximately 100,000 times for rewriting 500
KB.)
-
When accessing external storage, do not power OFF
or reset the display unit, or disconnect external storage. You may
damage the external storage.
-
To ensure safe CF card usage, create special
application screens that prevent access to the CF card. Use the
screen when performing operations like turning the display unit
OFF, resetting the display unit, opening or closing the CF card
cover, or inserting and removing the CF card.
-
When ejecting a CF card, make sure the CF card
access lamp (LED) is OFF. Data on the CF Card may be damaged.
-
When installing external storage, please be
careful on the front and back position of the external storage and
its connectors. If the position is incorrect, you may lose your
data or damage the external storage and display unit.
-
Do not transfer screen data (Send Project) to the
display unit or enter OFFLINE mode while writing data to external
storage. This may result in an incomplete file or damage to
external storage.
-
Please back up the data on the external storage
device.
-
Please refrain from doing the following, as it
can result in damage to data and equipment:
-
Leaving it exposed to static electricity or
electronmagnetic waves
-
Leaving it exposed to high temperatures, such as
those caused by direct sunlight or heaters
-
Bending the CF Card
-
Dropping the CF Card
-
Spilling water on the card
