[Calculation for the Q06CCPU-V(-B)]
The timeout time is determined by the following calculation formula.
Timeout time =
tcp_keepidle + (tcp_keepintvl
Initial value: 15000 (4 hours and 10 minutes)
tcp_keepidle: Time from line disconnection to the first retry (s)
Initial value: 14400
tcp_keepintvl: Retry interval (in 0.5s units)
Initial value: 150
tcp_keepcnt: Number of retries
Initial value: 8
[Settings methods for the Q06CCPU-V(-B)]
The following explains how to set the initial value to 4 hours and 10 minutes.
• Setting while the C Controller module is in operation
1) Connect the line to the C Controller module with the Telnet tool.
2) Set the following three external variables with the Telnet tool to change
the timeout time to the initial value.
tcp_keepidle = 14400
tcp_keepintvl = 150
tcp_keepcnt = 8
3) Close the Telnet connection.
• Setting at the timing of starting the C Controller module
1) Describe the following three external variable settings on the script file,
"STARTUP.CMD".
tcp_keepidle = 14400
tcp_keepintvl = 150
tcp_keepcnt = 8
2) Write the above script file, "STARTUP.CMD" to a CompactFlash card,
and insert it into the C Controller module.
3) Upon start of the C Controller module, the timeout time is set to the
initial value.
