Периодическая потеря связи с модулями WB

Deemon · November 18, 2023, 5:22am

Здравствуйте. Есть WB-6 (A6AM6Z3X) обновил прошивку Release name wb-2310. Short SN AZ545RAR. Подключено 4 модуля WB по RS485 и влогах наблюдаю периодические обрывы связи. Скорость 9600. Попытался обновить прошивку модулей (wb-mcu-fw-updater update-all), пишет что модули устарели. И еще мне кажется стало очень долго открываться “Настройка драйвера serial-устройств#!//etc/wb-mqtt-serial.conf”. Раньше этот раздел открывался также быстро как и остальные. Что можно сдел

ать чтобы решить проблему с обрывами связи и обновлением модулей.

Насколько периодчические? Точнее - как часто? При выполнении опроса с помощью modbus_client - постоянной удачно опрашивается?

Ну и - как собрана шина, присутствуют ли терминаторы?

Скорость “открытия” интерфейса настроек определяется тем как быстро собирается файл схемы, да в актуальных релизах это занимает 3-7 секунд на WB7.

Устройства выпущенные до (примерно) конца 2019 года - не имеют bootloader и не могут быть обновлены.

Deemon · November 20, 2023, 5:59am

Все четыре модуля подключены витым проводом длинною 5-7 см на прямую с клемной колодки контроллера wb6, без использования промежуточных терминалов. Как точно узнать версию модулей, есть или нет bootloader?

Кусок лога я прикреплял в прошлом файле.

Тут лучше всего - фото подключения.

Например - написать сюда их серийный номер.
Я проверю - есть ли возможность обновления. Также пришлите, пожалуйста, архив с диагностической информацией контроллера. Создание архива описано в документации.

Шина должна быть витой парой, это обязательно.

Не ищется, проверьте номер.
судя п диапазону, если старшая часть 42646 - то начало 2021 года.

Переделал подключение. пропала связь с одним из модулей. Такое раньше тоже было. потом само появлялось. В чем может быть причина?

BrainRoot · November 21, 2023, 12:09pm

Отсутствие контакта, отсутствие питания. Это основное.
Покадите результаты опроса с помощью Утилита «modbus_client» — Wiren Board

Deemon · November 24, 2023, 5:34am

Контроллер WB был отключен пару дней. После подключение датчики температуры стали сами опрашиваться. При этом не чего не делал.
