Chapter 1 Introduction to CBEH Multifunction Ethernet
Communication Module
1.1 Summary
FBs-CBEH series is a compact communication expansion board that does not take up
additional module space. Through this expansion board, the FBs-CPU module can
communicate actively (client mode) or passively (server mode) with the controllers
through Ethernet. This expansion board is compatible with all FBs-CPU modules.
Through this expansion board, the goal of remote PCL monitoring and diagnostics
can be easily accomplished.
Communications Port1 and Port2 will be used when this expansion board is applied.
Port1 is fixed as FATEK Slave operation mode and can be used for the editing and
debugging of ladder programs. Port2 is used to support the Modbus-TCP or FATEK
client operation mode. When operating, the parameters of communication ports
Port1 and Port2 will be configured automatically according to the work mode set.
In addition to the functions mentioned above, this product also provides a web
server function; besides providing the function of setting the module’s configuration
contents through a web browser, it also provides user with the ability to custom
design a webpage that is easy to operate. Through this function, the user can use the
customized webpage to easily browse or control the status within the PLC.
The difficulty to grasp and the too-specialized internet firewall setting of dynamic IP
have always been problems faced by internet remote maintenance applications.
This product provides an active remote service call back function that can completely
eliminate these problems. If only used for remote maintenance, under most
circumstances, it can be immediately used without the need to setup.
When a situation arises on-site, the Email sending function of this expansion board
can be used to notify the remote maintenance personnel, or use the Email to SMS
internet service to provide a more real-time SMS(Text) messaging to notify the
maintenance personnel.
1.2 Main Product Functions
PLC internet data communication
The FBs-CBEH series expansion board provides a PLC internet connection solution,
achieving Fatek or Modbus protocol data communication applications through this
expansion board’s Port1 and Port2.
Customized web page design
The FBs-CBEH series expansion board provides a web server function; in addition to
the built-in system webpage, it also allows user to easily browse or control the status
within the PLC through a customized web page. This customized web page can be

6
easily designed by using the companionate software “Easy Web Designer”; it does
not require any knowledge of HTML language or programming skill used for web
pages design.
Email sending
For a more responsive maintenance requirement, the FBs-CBEH series expansion
board provides the Email sending function. When special situations occurred on the
workstation, the ladder program can issue the “send Email command”to the CBEH
and further send an Email to notify the maintenance personnel. In addition, through
Internet service provider that provides “Email to SMS”sending functions, real-time
notifications by SMS also can be achieved.
Internet clock Synchronization (SNTP, Simple network time protocol)
The FBs-CBEH series expansion board provides the internet clock synchronization
function, eliminating the trouble of manually correcting the time on a regular basis.
Remote maintenance-Active call back
