Appendix C. NL200/201 Settings
C-6
This setting specifies, for a given port, the explicit list of PakBus node addresses
that the NL200/201 will accept as neighbours. If the list is empty (the default
value), any node will be accepted as a neighbour. This setting will not affect the
acceptance of a neighbour if that neighbour’s address is greater than 3999. The
formal syntax for this setting follows:
neighbour := { "(" range-begin "," range-end ")" }.
range-begin := pakbus-address. ;
range-end := pakbus-address.
pakbus-address := number. ; 0 < number < 4000
RS-232 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)
RS-232 TCP Serial Client IP Address
This setting specifies the IP address of the outgoing TCP Serial client connection
that the device should maintain. If the connection fails, the device will retry until
the connection succeeds. No entry specifies that no client connection will be
made.
RS-232 TCP Serial Client Port
This setting specifies the TCP port of the outgoing TCP Serial Client
connection.(range 1..65535)
C.3 CS I/O Tab
CS I/O Configuration
This setting controls which process will be associated with the CS I/O port. The
following values are defined:
TCP Serial Server
The device will listen for an incoming TCP connection from a remote client.
The port number of the listening connection is specified in the “RS-232 TCP
Port Number” setting. Data received on the TCP connection will be
forwarded to the RS-232 port, and data received on the RS-232 port will be
forwarded to this TCP connection.
PakBus
This port uses the PakBus protocol.
Modbus/TCP Gateway
The device will listen for incoming MODBUS/TCP connections from a
remote client. The port number of the listening connection is specified in the
“RS-232 TCP Port Number” setting. The device will convert incoming
MODBUS/TCP frames to MODBUS/RTU and forward them to the RS-232
port. The device will wait for a response from the MODBUS/RTU device
and forward the response back to the remote MODBUS/TCP client over the
established TCP connection.
Disabled
This port will not be used.
