== Device signature ==

The 6-byte module signature is stored at address 200. The signature is unique for each model of Wiren Board devices and allows to identify the model by Modbus:

! style="font-weight: bold;" | Module

! style="font-weight: bold;" | Signature

To get the signature of a device you need to run command READ_HOLDING_REGISTERS at 200 (length of 6 registers). Writing to this area of memory is not supported, and error 3 is returned when attempting to write to an invalid location. Empty spaces in the signature text are clogged with the value 0x00.  

Starting from register 220, the firmware build date is recorded, in the format ''number'''x00'''time'''x00''''' as a string (example: 'Jan 27 2017 17:01:13'). The length of the record is 21 registers.

== Command-line device management ==

The Wiren Board controller software includes  modbus_client utility to work with devices connected to the RS-485 outputs, via Modbus Protocol, the detailed description of the command is on the page [[Modbus-client/en| Modbus client]]. Access to the command line is described in [[SSH/en| SSH]].

=== Register reading example ===

Let's check whether it is true that we are connected to the module of the desired type. (Module wb-mqtt-serial needs to be stopped). At address 200, a unique signature of 6 registers is stored. Let's read 6 registers, starting with the address 200, and convert the received hexadecimal answer into a character string:

<syntaxhighlight lang="bash">echo  -e `modbus_client --debug -mrtu -pnone -s2 /dev/ttyRS485-1 \

As a result of the command we receive string  '''WBMS'''. The WB-MS module in the example has Modbus address 1.
