Wb-mqtt-serial: terminate called after throwing an instance of 'TRegisterValueException

1

Добрый день.
После установки последнего апдейта (apt update && apt upgrade && wb-mcu-fw-updater update-all):

Быстрая реакция на датчик движения WB-MSW в правилах!
В прошивке 4.31.0 и wb-mqtt-serial 2.95.1 появилась поддержка опроса регистров датчика движения через события в быстром Modbus.
Это регистры:
280 “Max motion”
283 “Current motion”

Wb-mqtt-serial стал вылетать и сыпятся ошибки, до обновления все работало исправно ошибок не было:

Это как раз причина.
То есть - проверьте шину.
А по поводу исключения - сейчас позову разработчика.

5

До обновления все работало нормально уже больше полгода ошибок не было, а тут резко появились? Все возможно конечно, буду проверять, почему до этого таких ошибок не было вот непонятно, видимо MSW доп нагрузку создают на шину.

Нужна помощь.

Локализовал проблему, отключая модбас шины (всего их 3 у меня), нашел ту изза которой происходят ошибки.

Отключая устройства нашел, что ошибки появляются когда включаю WB-MWAC.
Конфигурация шины: контроллер - 6х WB-MSW - WB-M1W2 - WB-MWAC - WB-MAP6S (+резистор 120Ом)
Отключил от WB-MWAC все клемники (чтобы исключить паразитное влияние датчиков или счетчиков), кроме питания + модбас, ошибки начинают сыпаться сразу после подключения, подключал этим же клемником соседний MAP6S ошибок нет. По питанию проблем быть не может +24В в шине.

Но при этом само устройство работает, становится активным в Устройствах и можно включать/выключать реле кранов. И это началось после обновления MSW, до этого ошибок в логах не было, я бы заметил.

Что может быть?

Обновил прошивки у всех MSW на предыдущую:

Решил обновлять на новую версию по одному и смотреть за ошибками (MWAC подключен к шине).
Обновил id:19 ошибок нет, обновил id:151 ошибок нет, обновляю id:12 и после старта mqtt-serial начинают сыпаться ошибки. Делаю наунгрейд прошивки для id:19, ошибки “почти” пропадают…

Вернул MWAC на место в конец шины и снова посыпались ошибки… пришлось сделать downgrade всем MSW и тогда ошибок нет.

Интересно.
А все MSW имеют синнатуру msw3G419? Или часть из них - другую?
в WB-MWAC прошивка - уже с поддержкой быстрого Modbus?
Если да - то прочитайте из него значение 113 регистра пожалуйста.
Ну и из MSW тоже.

Вроде бы да все, но нет один другой:

Через сканер ищется со значком молнии “1.20.1”, думаю с поддержкой уже.

Если правильно команду нашел, то ответ у всех “Data: 0x0000”, но я перевел все MSW на версию 4.29.11.

Еще было бы полезно в логах wb-mqtt-serial писать порт где ошибка случилась:

WARNING: [serial client] Reading events failed: Serial protocol error: malformed response: invalid crc
