Precautions when accessing the high speed data logger module
(1) Web browser operations, settings
In the local area network (LAN) setting of the Web browser, do not set a proxy server
for the local address. ( Section 5.3.1)
(2) FTP server function
(a) Because of FTP client side application restrictions, if the user name or password
is input incorrectly, end the FTP operation and redo the FTP connection from the
beginning.
FTP may not operate correctly by reentering the correct user name or password
with the 'user' FTP command.
(b) The maximum number of simultaneous connections to the FTP server is 10.
However, depending on the FTP client, it may make multiple simultaneous
connections, so an FTP client may not be able to login even if 10 clients are not
connected.
In this situation, shutdown all the FTP clients, then restart and connect them.
(c) If transferring many files at once with FTP, a 426 (Data connection error) may
occur.
In this situation, split the files up over multiple transfers and retransfer them.
(d) When using Internet Explorer as an FTP client, the user authentication screen
may not be displayed because of the Internet Explorer specification.
To enable the high speed data logger module's access authentication function,
enter the address in the following format.
ftp://<user name>:<password>@<high speed data logger module's address or
hostname>/
(e) When using Internet Explorer as an FTP client, data logging files, event logging
files, report files, and recipe files may not be opened directly because of the
Internet Explorer specification. Open those files after saving them to a personal
computer.
(f) When using Internet Explorer as an FTP client, because of the Internet Explorer
specification, errors may not be displayed even if the transfer failed when files are
transferred to the CompactFlash card which does not have enough free space.
Update the display and check if the files are transferred normally.
(3) Replacing old version module with new one
When a high speed data logger module is replaced, make sure to delete the
temporary Internet files of Web browser (cache) before accessing the high speed data
logger module. ( Section 10.3 POINT)
(4) Connecting GX LogViewer
The maximum number of connections for GX LogViewer to access high speed data
logger modules simultaneously is 2.
