(Новая страница: «In templates for devices that support fast Modbus, event handling is enabled for all registers where event generation makes sense. In some cases, it may be necessary to disable events, for example, if the use of non-standard protocol functions is prohibited by the company's security policy. There are currently no specific tools for working with events in the controller's web interface. To disable events, you can do the following: #In the device template, cha...»)

Only one device can respond to an event request at a time. Therefore, if multiple devices generate events, the one with the lower slave ID will be the first to respond to the request. Devices perform arbitration to determine this, which is described in detail on [https://github.com/wirenboard/wb-modbus-ext-scanner/blob/main/protocol.md GitHub].
На запрос событий одновременно может ответить только одно устройство. Поэтому если события сгенерировали несколько устройств, то первым на запрос ответит то, у которого меньше slave ID. Чтобы это выяснить устройства проводят арбитраж, который подробно описан на [https://github.com/wirenboard/wb-modbus-ext-scanner/blob/main/protocol.md github].
