Features
Logic Engine®
The Web server CPU module features the Logic Engine® to achieve fast execution of instructions — 0.056 μs for a basic
instruction (LOD) and 0.167 μs for an advanced instruction (MOV). This improves real-time performance for executing the
user program.
Basic Functions
The Web server CPU module is fully equipped with functions as a programmable logic controller to achieve the best
system.
USB Port
The Web server CPU module has a built-in Mini-B type USB port as standard. By connecting your PC to the Web server CPU
module with a USB cable, it is possible to switch the operating status of the Web server CPU module, confirm the I/O status,
change register values, update programs, and perform system program updates.
Powerful Functions with the Ethernet Port
Various communication functions, such as server/client communications, Web server, E-mail, and SNTP, are possible
through the built-in Ethernet port.
An overview of each function is shown in the table below.
Optional Modules
The Web server CPU module can be expanded with a variety of optional modules and function modules, enabling you to
add functions to match your application. If the optional modules and function modules are installed to the Web server
CPU module, the following functions can be expanded.
Memory Cartridge
A user program can be stored in an optional memory cartridge using WindLDR. The memory cartridge can be installed on
another CPU module to replace the user program without the need for connecting to a computer. The original user
program in the CPU module is restored after removing the memory cartridge. The user program can also be downloaded
to the CPU module so that the user program in the memory cartridge is retained in the CPU module even after the
memory cartridge is removed.
Clock Cartridge
An optional clock cartridge can be installed on the CPU module to store real time calendar/clock data for use with
advanced instructions to perform time-scheduled control.
Function Description
Maintenance Communication
Server
The user program can be downloaded, uploaded, or monitored using WindLDR via Ethernet.
Server Connection
Modbus TCP server, user communication server, or maintenance communication server can
be selected and used with each server connection. A maximum of eight server connections
are available.
Client Connection
Modbus TCP client or user communication client can be selected and used with each client
connection. A maximum of three client connections are available.
SNTP (Obtain current time)
The current time can be obtained from an SNTP server. The time obtained from the SNTP
server can also be written to the clock cartridge to adjust the time. The time zone can be
configured within the range of GMT-12:00 to GMT+13:00.
Send E-mail
A maximum of 255 e-mails can be configured and each e-mail can be sent using EMAIL
instructions. English, Japanese, Chinese, Western European, and Unicode are supported so
that you can use a variety of languages to configure e-mails.
When using English, the length of the e-mail subject can be up to about 180 characters, and
the e-mail message body can be up to about 1500 characters.
Data register values can be embedded in the e-mail message body.
Web Server
The status and data register values of the Web server CPU module can be monitored, and
data register values can be modified in the Web browser.
Web pages created by the user can be imported to WindLDR and downloaded to the CPU
module. The maximum capacity of the user web page is 1MB.
Data register values can be displayed and modified in the user web page.
PING PING can be sent using PING instructions to confirm if the specified remote host is active.
