Modbus TCP can be used to both '''get''' and '''set''' certain router parameters. First lets do an overview of how to obtain parameters via Modbus TCP. Please keep in mind that in order to get routers parameters when using '''[https://wiki.teltonika-networks.com/view/{{{name}}}_Modbus#Requests_configuration Request Configuration]''' you need to use '''Register Number''' instead of '''Register Address'''.{{#ifeq:RUTX12| RUTX12| To get data from the second modem, you need to execute this command:

For the first example, lets use a modbus read command to attempt to obtain 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:

'''-w''' specifies the data type. In this case, unsigned 16 bit integers.

'''{{#ifeq:{{{series}}}TRB14X|192.168.2.1|192.168.1.1}}''' - the router's LAN IP address.

'''{{#ifeq:{{{series}}}|TRB14X|192.168.2.1|192.168.1.1}}''' - the router's LAN IP address.

'''%MW001''' specifies the register address.

'''%MW001''' specifies the register address.

Lets examine a different, more complex example by issuing a request for the router's '''WAN IP address'''. If you look at the '''[[Monitoring_via_Modbus#List_of_parameters|table]]''' above, you will see that the WAN IP address value is contained within the 139th and 140th registers. Therefore, we should specify the 139th address and read 2 registers from that address:

Some values like Hostname, Router name, Network type are represented as text in their original form, but are stored in registers as numbers. You can interpret these values the same way as all discussed before (by converting them to binary and then to text), but a simpler way would be to get them in '''hexadecimal''' form and then convert them to text. To do so, we'll have to add the '''-D''' parameter to the command. Lets do it by asking for the router's Hostname:

As you can see most of the values are '''0''' and '''1''', 0 meaning OFF and 1 meaning ON. For example, if you want to turn '''WiFi OFF''', this command should be used:

In the case of '''SIM switch''' there are three values - '''0''', '''1''' and '''2'''. 1 makes the first SIM card slot in use, 2 makes the second SIM card slot in use and 0 initiates a switc from the SIM card in use to the opposite SIM card. For example, to initiate a switch to the second SIM card the command should look like this:

The '''reboot''' function only takes one value: '''1'''. It simply reboots the router. To initiate a reboot, use this command:
