The WB-MRM2-mini v.1 featured all-in-one terminal blocks and a lower height (46 mm). The module is mnaged from the controller [[Wiren Board 6/en|Wiren Board 6]] or a computer via the bus [[RS-485/en| RS-485]] via [[Relay Module Modbus Management/en |Modbus Protocol]], as well as via external buttons connected to the module. Miniature dimensions of the module allow you to mount it next to the load in the cable channels, bowls lamps, deep installation boxes for sockets and switches. | ||

The screw-free terminals b1 and b2 of the module have 2 inputs of the dry contact type, not isolated from the power supply. RC chains are used on each input line to eliminate contact chatter. The inputs are pulled up by resistors to the +3.3 V power line. Buttons or switches with locking are connected between the GND pin and the corresponding b1 or b2 input. The inputs can be used as general-purpose inputs, for counting signals and for direct control of relay channels. | The screw-free terminals b1 and b2 of the module have 2 inputs of the dry contact type, not isolated from the power supply.

The inputs have several modes of operation: trigger mode (for control with buttons) and repeat mode (for control with switches). In the trigger mode, to change the state of the relay, it is enough to close and open the input once. The change of state occurs on the rising edge (that is, when the circuit). In the repeat mode, the relay state is determined by the input state: the input is closed — the relay is on, open — the relay is off. Details about the mode switching are written in [[ Modbus Management | The inputs have several modes of operation: trigger mode (for control with buttons) and repeat mode (for control with switches).

The new device is added to the web interface in the section of the corresponding RS-485 port. In the web-interface on the right panel select Configs -> Serial Device Driver Configuration. In the /dev/ttyAPP1 port settings, add a new device (WB-MRM2 or WB-MRMR2-old, see below) by clicking on the '+ Serial device' button in the List of Devices section. Then specify the address of the device and select its type.

Note: the green Status led on the back of the WB-MRM2 module has started to flash intermittently, which means that the Wiren Board is communicating with the module. | Note: the green Status led on the back of the WB-MRM2 module has started to flash intermittently, which means that the Wiren Board is communicating with the module. | ||
The WB-MRM2 device is standard, so its description is specified in the template that is stored on the Wiren Board controller in the file /usr/share/wb-mqtt-serial/templates/config-wb-mrm2.json. | |||
In modules with firmware version up to 1.5.4 inclusive, another register card was used, where the state of the inputs was described by the discrete registers 0 and 1, in newer devices the holding registers 7 and 8 are supposed to be used. If you are using an older device, use the /usr/share/wb-mqtt-serial/templates/config-wb-mrm2-old.json. template to work correctly. | |||
== | == Module Control via the Wiren Board web interface == | ||
An example of controlling a WB-MRM2-mini relay module with a Wiren Board 6 controller and programming control scenarios will be discussed in a simple layout, where the relay module is the only device connected to the controller (see the diagram in [[#Mounting|Mounting]]). Normally open button without fixation is connected to input 1 and GND. 12 V power is supplied to the V+(+) and GND (- ) inputs. The RS-485 A and B inputs/outputs of the first controller port and the WB-MRM2-mini module are connected. | |||

Using virtual switches Relay1 and Relay 2 in the web-interface, you can control the corresponding outputs of the module and monitor their status. If the relay is turned on or off via the external input, it will be reflected in the web-interface. | |||
The current state of the inputs is indicated by the Button 1 and Button 2 checkboxes (they cannot be clicked to change the state). Press/enable counters are displayed in the Button 1 counter – Button 2 counter fields. The meter values are stored in the memory of the relay module microcontroller and are reset when the power is turned on/off and reset. | |||
The Safety Timer slider allows you to set the shutdown time (in seconds) of all outputs when there is no communication with the Wiren Board (0 – the safety timer is disabled). When communication with the controller is resumed, the switched-off relays will remain switched off. The slider is easy to control with the arrow keys, previously focusing on it with the mouse: moving the slider with the mouse does not provide sufficient accuracy. The safety timer allows stopping technological processes in case the control over the module is lost (for example, the RS-485 cable is broken). Always consider the possibility of losing communication with the controller when designing control systems. | |||

Details of the work with the module via Modbus Protocol are written in [[Relay Module Modbus Management/en|Управление модулями реле Wirenboard по протоколу Modbus]]. | |||
== | == 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 | Firmware Changelog]]. | |||
