Each input controls the state of the corresponding relay. | Each input controls the state of the corresponding relay. | ||
The inputs have two 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 — off. Details about the mode switching written in [[ Modbus Management | The inputs have two modes of operation: trigger mode (for control with buttons) and repeat mode (for control with switches).

The current flowing when the button or switch is closed is small, so the type of button or switch can be any. Despite the built-in protection against rattle, choose quality buttons and switches to avoid false alarms due to bad contacts. | The current flowing when the button or switch is closed is small, so the type of button or switch can be any.

If the device is the last one on the RS-485 line, a 120 Ohm resistor-terminator must be installed between its inputs A and B. Practice shows that in case of bench tests with a small length of the RS-485 line and a small number of terminator devices, it's not necessary to install terminator on the last device in the line. | |||
The module must be installed to meet the requirements of electrical safety and to prevent accidental contact of contacts under high voltage. The module must be operated under recommended environmental conditions. | |||

The choice of a quality power supply is very important for the operation of the module. A button with green wires connected to the module input 0 disconnects all channels simultaneously.]] | ||
== | == Control of the module via the Wiren Board web interface == | ||
The device uses the WB-MR6F template. Each channel corresponds to three switches that control three relays in the group: K1, K2, K3 belong to the first channel, K4, K5, K6 - to the second. | |||
The relay corresponds to the position of the outputs: | |||

Using virtual switches K1-K6 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 Input1 — Input6 checkboxes (they cannot be clicked to change the state). Press/enable counters are displayed in the Input 1 counter – Input 6 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). | |||
A button connected to input 0 allows you to turn off all the relays included in the module with a single press. Pressing again will turn on all the relays that were switched on initially. The status of the relay is stored in memory, so if you press the button again after a power failure, the restoration of the relay will not happen. The ability to restore relay status after power supply interruption as described in section [[#Relay operation mode in case of power failure| Relay operation mode in case of power failure]]. | |||
== | == Relay operation in case of power failure == | ||
Depending on the value written to the storage register 0x06, after the power is turned off and restored, the relays will remain off (if the value is 0, or turn on those that were turned on before the power interruption if the register has a value of 1). This feature appeared in the modules with the firmware, starting with version 1.5.3. | |||
== | ==Modbus Control== | ||
Details of the work with the module via Modbus Protocol is written in [[Relay Module Modbus Management/en| Relay Modules Modbus Management ]]. | |||
There you can also find a map of the device registers. | |||

== | == 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]]. | |||
