When using CF card or USB storage, check the
restrictions identified in the following.
5.5.3 Restrictions on
External Storage Usage
-
Up to 8999 folders can be registered. Only one
folder can be stored in backup memory (SRAM).
-
The size of one folder can be up to the same size
as the total capacity of the backup memory SRAM when only recipes
are stored.
Even when filing data is stored on a CF Card/USB storage device,
regardless of the CF Card/USB storage memory capacity, one folder
must have a capacity equal to the backup memory's (SRAM) maximum
capacity.
-
Up to 2048 files can be set in one folder.
-
Up to 1650 blocks can be saved in one file. (The
maximum number changes depending on the Number of Files and Number
of Data Items.)
-
The maximum amount of data in one block is 10000
for 16-bit data, or 5000 for 32-bit data. (The maximum limit
depends on the number of files and number of blocks.)
-
The more data transferred to the device/PLC, the
more time it takes to complete the write operation. The time from
when transfer starts to when transfer is complete can vary from
several seconds to several minutes.
-
While writing to a device/PLC, the display of
Parts may not update properly or may become slow. Screen changes
and other operations may also become slow.
-
If a screen change occurs during transfer, in
order to read the screen information, it may take some time to
write to the device/PLC.
-
If data exceeding the device range of a
device/PLC is transferred, an error occurs and no transfer is
performed.
-
Wait until a transfer completes before initiating
another one. If a transfer is started before the previous one ends,
such as when an automatic transfer and manual transfer occur at the
same time, the second transfer operation may not be accepted.
-
If a project transfer or changing to offline mode
is perfomed while transferring data, the data may not be
transferred completely.
-
Data in backup memory (SRAM) is erased on:
-
Transfer Project (Send Project)
-
Offline mode's [Initialize User Memory]
-
Offline mode's [Initialize Backup SRAM]
-
Do not duplicate an ID Number for the Special
Data Display [Filing] on all screens
-
The generated filing data cannot be used with
other projects.
-
When the following actions are performed after
creating a filing data in CF Card or USB storage, please re-save
the filing data in the CF Card or USB Storage.
-
Save as a project name.
-
Change/Add/Delete Device/PLC
-
In Device-Specific Settings, add/delete
Individual Display Unit.
However, if the [Transfer CF Files] check box
is selected in the transfer settings, the latest data will be
transferred without re-saving the data in the CF Card.
