modbus_ports PORT_NUMBER slave_response_timeout TIMEOUT
Set response timeout (serial slave) in ms. When this timeout expires, delayed frames are dropped.
Example:
modbus_ports 1 slave_response_timeout 2000
If a subcommand that normally sets a value is not given an argument, it will print the current value.
Example:
modbus_ports 2 baud
Set baud rate is 115200
PORT_NUMBER is a number of ports in modbus gateway and it is counted from 0.
modbus_routing
modbus_routing help
Print routing's help.
modbus_routing show
Display all active routing table in system.
[LP]: [SLAVES NUMBERS] [IP/HOSTNAME] [PORT] [TIMEOUT]
modbus_routing add SLAVE_ADDR HOSTNAME PORT TIMEOUT
SLAVE_ADDR with HOSTNAME PORT is used by uarts working in Modbus router mode. TIMEOUT (in ms) is used to close the connection if a slave is not responding. The maximum records is 8. One record for one address/ip.
Example:
modbus_routing add 18 192.168.0.10 502 2000

Example:
modbus_routing add 18-25;* 192.168.0.10 502 2000
Example:
modbus_routing add 18-25 modbus.local 502 2000
modbus_routing remove [HOSTNAME_NUMBER/all]
Remove Modbus Routing Table record. HOSTNAME_NUMBER is line number from /show/ command.
Example:
modbus_routing remove 2
Example:
modbus_routing remove all
