Precautions

■1. Handling data strage during the access
Do not remove the data strage and do not open the SD card slot during the access.
Doing so may damage files in the GOT or in the data strage.
■2. Connection to the PLC CPU
To use the log viewer function using the PLC CPU, the FTP setting is required on the PLC CPU.
The FTP setting methods for GX Works3 and GX Works2 are described below.
• In case of GX Works3
Display the module parameter window of the CPU used, and select [FTP Server Setting] from the [Application
Setting] tree.
Select [Use] in [FTP Server Use or Not].
• In case of GX Works2
Display the parameter setting window of the CPU used, and select the [Built-in Ethernet Port setting] tab.
Click the [FTP Setting] button and select [Use] in [FTP].
For the details of GX Works3 and GX Works2, refer to the following.
➠
■3. Access to storing files
[Storing file] is for use in temporarily storing the data currently collected by the high speed data logger module, the PLC
CPU, or the BOX data logger.
Precautions for accessing to [Storing file] are different according to the controller.
(1) High speed data logger module and BOX data logger
• During the file switching from [Storing file] to [saved file], [Storing file] and [saved file] may not exist temporarily.
• When [Storing file] is selected and an error message saying that the file cannot be found appears, select [Storing
file] again.
• Since data is stored in [Storing file] as needed, the copied file size may be larger than the size of when [Storing file]
is selected.
• The data is also stored as needed even when [Storing file] is being copied, so the copying file size may appear
larger than the file size of when selected.
➠
(2) PLC CPU
Reference and copying are not available since [Storing file] cannot be selected.
When [Storing file] is full, the data cannot be browsed until the file is switched to [saved file].
➠
The following shows the storage location of [Storing file] and [saved file].
