For example, lets use this command to get the router's uptime value. If you look back at the table above, you will see that the uptime value is stored in two registers starting from the first register, therefore:
For example, lets use this command to get the router's uptime value in seconds. If you look back at the table above, you will see that the uptime value is stored in two registers starting from the first register, therefore:
$ modbus read -w -p 12345 192.168.1.1 %MW001 2
$ modbus read -w -p 12345 192.168.1.1 %MW001 2
