Appendix C.  NL241 Settings 

C-12 

CS I/O TCP Timeout  

This setting, in units of seconds, will determine how fast the CS I/O serial 

server will time out if no activity is detected. Set to 

0

 for no time-out (not 

recommended) (range 0 to 999). 

CS I/O PakBus Beacon Interval  

This setting, in units of seconds, governs the rate at which the NL241 will 

broadcast PakBus® messages on the CS I/O port in order to discover any new 

PakBus neighboring nodes. It will also govern the default verification interval 

if the value of the 

CS I/O Verify Interval

 setting is set to

 0

CS I/O PakBus Verify Interval  

This setting specifies the interval, in units of seconds, that will be reported as 

the link verification interval in the PakBus® hello-transaction messages. It will 

indirectly govern the rate at which the NL241 will attempt to start a hello 

transaction with a neighbor if no other communication has taken place within 

the interval. 

CS I/O Modbus Timeout

 

This setting determines how long, in milliseconds, the MODBUS/TCP to 

MODBUS/RTU gateway will wait for an answer from the MODBUS slave 

device(s) attached to the 

CS I/O

 port. If no answer is received within the 

timeout period, the MODBUS/TCP server will reply to the MODBUS/TCP 

client with error code 0x0B (Target Device Failed to Respond).  

C.5  Net Services Tab 

Telnet  

Enables/Disables the telnet service. 

Telnet Port Number  

The default TCP port number for the configuration monitor telnet session is 23. 

This entry makes it possible for the user to change the telnet session port 

number if desired. Typically, it is not necessary to change this entry from its 

default (range 1 to 65535). 

Telnet Timeout 

This setting, in units of seconds, will determine how fast the configuration 

monitor telnet session will time out if no activity is detected. Set to 

0

 for no 

time-out (not recommended) (range 0 to 999). 

Ping (ICMP)  

The NL241 will not respond to Ping requests if this setting is disabled.
