■ No-response timeout
If no-response has come back from the client, packets (keep-alive packets) can be sent at fixed
time intervals to verify if the other party is present. This parameter sets the time interval between
transmissions of these packets.
If no-response state continues for a specified time (setting time × 3 [Default is 15 seconds]), then
the robot controller determines that an error has occurred and automatically cuts the TELNET
connection. Setting to "0" (zero) will not send keep-alive packets so the connection with the client
is not automatically cut even if no-response state continues.

* Depending on the network, response time may be longer and an apparent "no-response" error
detected. If this happens, change the setting as needed. (Internet, etc.)
* The controller automatically sends keep-alive packets. These packets do not affect the user
transmit/receive data.
