(a) Precautions on Telnet connection
If the line is disconnected during use of Telnet, it cannot be reconnected until TCP
connection including the Telnet on the C Controller module side times out.
If line disconnection occurs during Telnet connection, reconnect it after timeout.
The timeout time for the C Controller module side Telnet (TCP) connection can be
changed by setting the values in the calculation formula and using one of the
setting methods introduced for each model.

[Calculation for the Q12DCCPU-V]

The timeout time is determined by the following calculation formula.
Timeout time = net.inet.tcp.keepidle
+ ( net.inet.tcp.keepintvl

Initial value for VxWorks: 7800000 (2 hours and 10 minutes)
