Overview of the Communication Functions
1.1 Relationship between the Communication
Function and the Ethernet and Serial Interfaces
The XL100 comes standard with an Ethernet interface for connecting a LAN cable and a
serial interface (RS-232/RS-485 and USB). To use the communication function of the
XL100, the Ethernet or serial communication settings must be configured in advance.
The following figure shows the relationship between the communication function of the
XL100 and the Ethernet and serial interfaces.

1.2 Explanation of Functions
This section gives an overview of the communication function that can be used to control
the XL100.
Modbus Communication
Modbus Slave
• The Modbus protocol can be used to read the measured/calculated data written to the
input register of the XL100 from a PC or write/read communication input data from the
hold register of the XL100.
•For details on the Modbus function codes that the XL100 supports, see section 4.1.
•This function can be used only when communicating via the serial interface.
•For a description on the settings required to use this function, see sections 4.2 and
4.3.
Modbus Master
• Loads the measured data and other types of data of other instruments using the
Modbus protocol as communication channel input. The loaded data can be scaled
and displayed with a unit that you assign. The data can also be handled on a
calculation channel.
•Function for writing data to other instruments is not supported.
•For details on the Modbus function codes that the XL100 supports, see section 4.1.
•This function can be used only when communicating via the serial interface.
•For a description on the settings required in using this function, see section 4.4.
Setting/Measurement Server
• This function can be used to set almost all of the settings that can be configured using
the front panel keys. This function cannot be used to (1) turn the power switch ON/
OFF, (2) set the user name/password for communications, (3) set the user name/
password for key login, and (4) set the destination of the FTP client function.
•The following types of data can be output.
•Measured/calculated data.
•Data in the internal memory or files in the external storage medium.
•Setup data.
•Log data of operation errors and communications.
•The commands that can be used through this function are setting commands and
output commands.
•This function can be used when communicating via the Ethernet or the serial
interface.
Maintenance/Test Server
•This function can be used to output connection information, network information, and
other information regarding Ethernet communications.
•The commands that can be used through this function are maintenance/test
commands.
•This function can be used only when communicating via the Ethernet interface.

Overview of the Communication Functions
FTP Server
• You can use a PC to access the XL100 via FTP. You can perform operations such as
retrieving directory and file lists from the internal memory or the external storage
medium of the XL100 and transferring and deleting files.
•This function can be used only when communicating via the Ethernet interface.
Note
Do not use this function while logging. Logging may be aborted due to file access.

FTP Client
•Automatic File Transfer
•The display data file and log data file that are created in the internal memory or
external storage medium of the XL100 can be automatically transferred to a remote
FTP server. The result of the transfer is recorded in the FTP log. The FTP log can
be shown on the XL100’s display or output to a PC using commands.

FTP client
You can specify two destination FTP servers, primary and secondary. If the primary
server is down, the file is transferred to the secondary server.
•This function can be used only when communicating via the Ethernet interface.
•FTP Test
•The file transfer can be checked by transferring a test file from the XL100 to a
remote FTP server.
• The result of the FTP test can be confirmed on the FTP log display.
•This function can be used only when communicating via the Ethernet interface.
1.2 Explanation of Functions

Login
•This function can be used only when communicating via the Ethernet interface and
when using the setting/measurement server, maintenance/test server, and the FTP
server functions.
•User Authentication
This function allows only registered users to access the XL100 in order to prevent
third party access from the network.
•Up to seven names can be registered. One of the names is fixed to administrator
privilege. For the other six names, you specify the access privilege when you
register the name.
•There are limitations on the number of simultaneous connections and the number
of simultaneous users accessing the XL100 from PCs (see section 2.1).
•Login to the FTP server is allowed only by an administrator or through anonymous
login (see section 2.7).
•Granting Access Privileges
This function grants access privilege (user level) to operate the XL100 for the
registered users. For example, this prevents user B (user level) from changing the
measurement conditions that were set by user A (administrator level).
• There are two user levels on the XL100, user and administrator.
• Administrator
An administrator has privileges to use all setting/measurement server functions,
maintenance/test server functions, and FTP server functions.
•User
A user has limited privileges to use the setting/measurement server functions,
maintenance/test server functions, and FTP server*1functions.
•Limitations on the use of the setting/measurement server
A user cannot change settings that would change the XL100 operation. A
user can output measured data and setting data.
• Limitations on the use of the maintenance/test server
A user cannot disconnect a connection between another PC and the XL100.
A user can disconnect the connection between the PC that the user is using
and the XL100.
•Limitations on the use of the FTP server
You cannot save files to the external storage medium of the XL100 or delete
files on it. You can load files.
*1User level access to the FTP server is allowed only by an anonymous user (see
section 2.7).
•Communication Timeout
This function drops the connection with the PC if there is no data transfer for a given
time at the application level. For example, this function prevents a PC from being
connected to the XL100 indefinitely which would prohibit other users from making new
connections for data transfer.
Web Server
•This function can be used only when communicating via the Ethernet interface.
•The XL100 display can be shown on a Web browser (for Web browsers that have
been tested for compatibility, see section 2.10).
•The following two pages are available.
•Monitor page: Monitoring screen (switching is possible among measurement
data displays, alarm summary display, and log displays)
