4. One of the two ports will be used for connection, depending on the MANU/AUTO mode.
5. The port will be enabled at the following intervals:
 When the initialization after power ON reset is complete
 When no IAI protocol serial-communication message has been received for approximately five
seconds after the completion of controller initialization
6. The port will be disabled at the following intervals:
 Upon reception of an IAI protocol serial-communication message (serial communication having
priority. If the PC software is connected via serial communication, Ethernet connection will be cut
off.)
 Upon mode change
 Upon software reset
7. If the controller is used as a client, a connection retry will be initiated within approximately two seconds
after the recognition of a connection failure (refused, timed out, failed, etc.).
8. For details on the message format, refer to the attached “X-SEL (Cartesian/IX SCARA) Serial
Communication Specification (Format B).”
[Example of operation check procedure when the controller is used as a server]
Set the port number for the host computer and utilize the telnet tool included with your windows operating
system to communicate to the host controller. Also, set the port on the X-SEL controller side to match by
setting I/O parameter #144 (MANU mode) or No. 159 (AUTO mode). Then perform data transfer in
accordance with the format defined in the Serial Communication in order to test communication.
The following is an example of a simple check using “telnet”:
“!992001234567890@@” + Enter = Send a “test call”
 Receive a response, “#99200123456789034”
CR/LF is appended at the end of the sending message by “telnet.”
Using “telnet” with “Local echo enabled” will make the operation easier.
