When using CF card or USB storage, check the
restrictions identified in the following.
5.5.3 Restrictions on
External Storage Usage
-
Saving a sampling group to CSV, system settings
[Save Data] operation, and back up sampling data to a CF Card/USB
Storage cannot run at the same time. These save operations are run
in the order the display unit receives the requests.
-
Set [CSV Save Control Word Address] with no
overlap among each sampling group or System Settings' [Save Data]
control word address. If you set overlapped, it will not operate
normally and the status cannot be obtained.
Refer to the following for saving a CSV file with System Settings'
[Save Data] setting.
20.8.2 Control
Word Address for Data Save
System Settings [Display Unit] - [Mode] tab
-
You cannot run automatic save on multiple
sampling groups at the same time. You cannot run auto save of each
sampling group and sampling data auto save using [Save Data] from
System Settings. A write error occurs.
-
When you save automatically, and the sampling
cycle time is short (sampling frequency is short or number of times
is small), the sampling cycle may be complete while writing to the
CF Card/USB storage device. If so, the sampling operation continues
only after the writing process for the sampled data is
complete.
-
When you save automatically, do not set very
short sampling cycles (sampling frequency is short or the number of
times is small). This can cause increased writing of data and
shortens the life of the CF Card/USB storage.
-
When you access backup memory (SRAM) using
Pro-Server EX, the CSV file output process is on standby. For auto
save, the sampling operation continues only after the writing
process for the sampled data is complete.
-
If a CSV file with the same name exists in a CF
Card/USB Storage, data is added to the file.
-
The CSV file is output in a partially fixed
format, which will not completely match the [Display/Save as CSV]
settings. For more details, please refer to the following.
25.11.4.1 CSV File Format
-
In the sampling group's Address, if the [Bit
Length] or [Addressing] change, the [Display/Save in CSV] format
will be reset.
-
When changing the [Display/Save in CSV] settings
from [Custom Settings] to [Basic], all customized settings will be
reset.
-
Please use the same data format for the numeric
value and total fields. If the formats differ, then the calculated
value may not display correctly.
-
When using the [Set number of files in
destination folder on external storage] property, you cannot access
the CF card with the WinGP or Pro-Server EX device access API
"define file type".
-
Although files with the same name are
overwritten, if the destination folder changes due to a change in
the [Number of files per folder] property, overwrite save
operations are not possible.
Changing the [Number of files per folder] also changes the folder
structure. As a result, before running initialization or other
tasks, you should back up data on external storage to media that is
used exclusively for this purpose.
-
When using Pro-Server EX's MES application to get
from the CF card, set [CSV Date Format] to [yy/mm/dd]. Normal
operations may not be possible with other date formats.
