Compatibility and Speed
Various Protocols Available on Ethernet
Improved FINS Message Communications
Use Web Function to Read Ethernet Option Board Settings and Status
Full Range of Functions for Handling Troubles
The transmission medium of Ethernet side has been upgraded to 100Base-
TX, while compatibility with some functions and application interfaces of the
existing Ethernet Unit models for CS/CJ series has been maintained.
Limited by the Toolbus protocol used on the serial side, the processing speed
is only 115.2kbps, slower than the existing Ethernet Unit. The FINS frame
length is less than 1,004 bytes, so the system response performance for the
same FINS message applications is longer than the existing Ethernet Unit.
A variety of protocols make a wide range of applications for use on an Ether-
net network. The protocols that can be selected include receiving commands
by OMRON's standard protocol FINS and reading Ethernet Option Board set-
tings and status by HTTP.
A communications service can be selected according to need, allowing the
PLC to be flexibly integrated with the Ethernet information network.
The following functions have been maintained according to the existing Ether-
net Unit models for CS/CJ series.
• The maximum number of nodes is 254.
• Communications are enabled even if the host computer's IP address is
dynamic.
• An automatic client FINS node address allocation function makes it possi-
ble to connect online to the PLC even if no FINS node address has been
set for the host computer.
• FINS message communications are enabled in both UDP/IP and TCP/IP,
but it are only enabled in TCP/IP with up to 2 simultaneous connections .
→
Previously it are enabled in TCP/IP with up to 16 simultaneous connec-
tions and all can be set to client.
• Multiple FINS applications, such as the CX-Programmer, on the same
computer can be connected online to the PLC via Ethernet.
A Web function is provided in Ethernet Option Board.
This enables use of a Web browser to read the Ethernet Option Board's sys-
tem settings and statuses.
A full range of functions is provided for promptly handling any troubles.
• Self-diagnostic function when power is turned ON.
• Error log for recording error information when an error occurs.
