Appendix C. NL200/201 Settings
C-7
CS I/O Serial Server Port Number
To communicate with a TCP/IP server, the client application must open a socket
to that server. The socket of a specific server is uniquely identified by an IP
address of the host where the server is running and a port number associated with
the server application on that host. This entry is where the port number of the
serial server is set. Typically, it is not necessary to change this entry from its
default. (range 1..65535)
SDC Address
Communication with the datalogger via the CS I/O port is done using SDC
(Synchronous Device Comms). The datalogger will address the devices with
which it wishes to communicate using an SDC address. The CS I/O port can be
configured to respond to SDC address 7, 8, 10, or 11.
CS I/O TCP Timeout
This setting, in units of seconds, will determine how fast the device will time out
on the open TCP connection. For Serial Server and MODBUS/gateway
configurations, the device will close the TCP connection if no activity is detected
for the timeout period. Set to 0 for no time-out (not recommended). (range 0..999)
CS I/O PakBus Beacon Interval
This setting, in units of seconds, governs the rate at which the NL200/201 will
broadcast PakBus messages on the associated port in order to discover any new
PakBus neighbouring nodes. It will also govern the default verification interval if
the value of the Verify Interval setting for the associated port is zero.
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 NL200/201 will attempt to start a hello
transaction with a neighbour if no other communication has taken place within the
interval.
CS I/O Modbus Timeout
This setting determines how long the MODBUS/TCP to MODBUS/RTU gateway
will wait for an answer from the MODBUS slave device(s) attached to the RS-232
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). (milliseconds)
C.4 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.
