Every 50 ms, the master sends a broadcast request on the bus, which is received by all devices on the bus. If a device generates an event, it sends a response containing the event identifier, its type, and additional data. If there are multiple devices that generate such events, they engage in arbitration, in which the device with a lower Slave ID wins. For more information about arbitration, please refer to [https://github.com/wirenboard/wb-modbus-ext-scanner/blob/main/protocol.md github]. | Every 50 ms, the master sends a broadcast request on the bus, which is received by all devices on the bus.
