interface » serial » {interface} » protocols » tcpmodbus » settcpmodbus
, where
{interface}
is
the serial port.
3. Configure the following parameter(s) as required:
Parameter

Synopsis:
A 32-bit signed integer between 50 and 10000
Default:
100

first character of the response. If the RTU does not respond in this time, the poll will have
been considered failed.
pack-timer { pack-timer }
Synopsis:
A 32-bit signed integer between 5 and 1000
Default:
1000
The maximum allowable time to wait for a response to a Modbus request to complete
once it has started.
turnaround { turnaround }
Synopsis:
A 32-bit signed integer between 0 and 1000
Default:
0
The amount of delay (if any) to insert after the transmissions of Modbus broadcast
messages out the serial port.
retransmit { retransmit }
Synopsis:
A 32-bit signed integer between 0 and 2
Default:
0
The number of times to retransmit the request to the RTU before giving up.
max-connection { max-connection }
Synopsis:
A 32-bit signed integer between 1 and 32
Default:
1
The maximum number of incoming connections.
local-port { local-port }
Synopsis:
A 32-bit signed integer
Default:
502
The alternate local TCP port number. If this field is configured, a single connection
(per serial port) may be made to this alternate port number. Note that Modbus TCP
uses a default local port number of 502. There is no limit imposed on the number of
connections to the default TCP port.
