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: | |||

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. | |||

Since firmware version 4.0.0, the WB-M1W2 Converter allows you to configure each of the two inputs as a discrete input. The input mode is set in registers 275-276 (see the table above). In Wiren Board controllers this mode is configured through the Setup-section of the driver. | |||
To display the registers corresponding to the discrete inputs, select the template "WB-M1W2 DI": | |||

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 we are connected to the module of the desired type. (Module wb-mqtt-serial should 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 answer from hexadecimal digits into a character string: | |||
<syntaxhighlight lang="bash">echo -e `modbus_client --debug -mrtu -pnone -s2 /dev/ttyAPP1 \ | <syntaxhighlight lang="bash">echo -e `modbus_client --debug -mrtu -pnone -s2 /dev/ttyAPP1 \ | ||

As a result of the command, we receive string '''WBM1W2'''. The WB-M1W2 module in the example has Modbus address 1. | |||
== | == Device firmware update == | ||
Starting with the new firmware versions of the device, the firmware update functionality (firmware) via the Modbus Protocol is supported. This makes it possible to extend the functionality of the devices and eliminate errors in the firmware directly at the installation site. Read more about flashing devices described in the article [[WB-MCU-Flasher|Download firmware to Wiren Board devices]]. A list of firmware versions that support the update, as well as devices for which this feature is implemented, can be found in [[Firmware_Changelog/en| Firmware Changelog]]. | |||
