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).
B.5 Net Services tab
B.5.1 Telnet
Enables/Disables the telnet service.
B.5.2 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).
B.5.3 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).
B.5.4 Ping (ICMP)
The NL241 will not respond to Ping requests if this setting is disabled.
B.5.5 PakBus Address
This setting specifies the PakBus address for this device. The value for this setting must be chosen
such that the address of the device will be unique in the data logger network. Duplication of
PakBus addresses in two or more devices can lead to failures and unpredictable behavior in the
PakBus network. When a device has a neighbor list or neighbor filter setting filled in for a port,
any device that has an address greater than or equal to 4000 will be allowed to connect to that
device regardless of the neighbor filter.
B.5.6 PakBus/TCP Service Port
This setting specifies the TCP service port for PakBus communications with the data logger.
Unless firewall issues exist, this setting probably does not need to be changed from its default
value.
