Ошибки по протоколу Modbus TCP

ADC · 02.Декабрь.2024 10:56:41

Добрый день, на объекте WirenBoard 7.4 опрашивает ESM по протоколу Modbus TCP.
Количество опрашиваемых регистров примерно 250 типа float.
Периодически появляются ошибки:

Dec 02 10:29:43 wirenboard-AF5R2CCQ wb-mqtt-serial[17843]: WARNING: [modbus] failed to read 2 holding(s) @ 406 of device modbus-tcp:1: Serial protocol error: request timed out

С чем они могут быть связаны?
Также скорость опроса составляет примерно 2 секунды каждого параметра. Реально ли уменьшить это значение до полсекунды?
Пробовал выставить значение “периода чтения” у каждого канала 500 мс, но в этом случае опрос происходит еще медленнее и появляются “желтые восклицательные знаки” в таблице на вкладке “устройства”.

На этом же объекте ESMы той же конфигурации с теми же регистрами опрашивает сервер также по протоколу Modbus TCP с периодичностью в 200 мс и проблем с опросом нет.

Добрый день.

Для диагностики проблемы пришлите, пожалуйста, архив с диагностической информацией контроллера. Создание архива описано в документации.

Добрый день, прикладываю архив.

Добрый день.
Обратите внимание на логи, судя по записям:

Устройство не отвечает на несколько подряд попыток соединиться. Причем не отвечает с периодичностью в 5-30 секунд.
Для диагностики - запустите ping к этому устройству, также попробуйте прочитать его регистры с помощью modbus_client. Лучше попробовать как с контроллера так и с компьютера, для того чтобы получить достоверную картину.

Объект расположен удаленно в месте с не с самой лучшей связью, поэтому пинг с компьютера вероятно даст не совсем достоверную информацию. Но могу все же попробовать, если это необходимо после выполненных шагов выше на контроллере.
Приложу файл лога за минуту опроса modbus_client
modbus_log.txt (12,4 КБ)

BrainRoot · 03.Декабрь.2024 07:59:56

Пинг и не нужен, с компьютера. Попробуйте запросить прочитать ответы по modbus.
Сейчас я вижу что при идентичном запросе

и

устройство отвечает разное.
Точно ли в сети одно устройство с такимс адресом? Я еще не видел чтобы slave то отдвал данные по регистру то возвращал отсутвие запрошенного.

ADC · 03.Декабрь.2024 08:23:18

Да, опрашиваемое устройство одно, это шкаф, где патч-кордом соединены 2 устройства - WB + ESM и все.

BrainRoot · 03.Декабрь.2024 08:38:36

Тогда - тем более непонятно. Устройство, по моему предстаавлению - должно на одинаковые (они ведь одинаковые, я точно сравнил) запросы давать всегда одинаковый ответ. Если запрашивать существующий регистр - то его значение. Если несуществующий - возвращать 0x8*.
Надо заметить что, возможно, устройство не способно отдвать значения с той частотой с котрой его контроллер опрашивает. Для проверки - остановвите wb-mqtt-serial и попробуйте снова с помощью modbus_client опросить, запросив в цикле сотню раз, например как тут: Увеличение скорости WB-MGE v.2 - #34 от пользователя BrainRoot

ADC · 03.Декабрь.2024 08:59:59

Пробросил 502 порт на компьютер с устройства и опросил при помощи modbus pool, логи прикладываю к сообщению, ошибок при опросе не обнаружил (100 это опрос 100 регистров, файл без цифры это 2 регистра)
Также на объекте работает сервер, который опрашивает 10 ESMов с частотой 200 мс, там также не было замечено ошибок в работе устройств.

modpool_log_100.txt (55,7 КБ)
modpool_log.txt (9,4 КБ)

BrainRoot · 03.Декабрь.2024 09:13:58

Отлично. Но раз в секунду - это очень медленный, проверьте увеличив частоту (уменьшив период до 200мс, можно до 50мс).

ADC · 03.Декабрь.2024 11:00:09

В целом опрос раз в 500мс был бы достаточным, прикладываю опрос раз в 200мс при помощи той же modbus pool
Загрузка: modpool_log_200ms.txt…
По поводу цикла пока что пробую, не совсем получается, чуть позже пришлю результат.

ADC · 03.Декабрь.2024 13:14:44

Провел несколько опросов в цикле, в результате ответ от устройства приходит редко. Wb-mqtt-serial при этом отключен.
Прикрепил несколько попыток:

Ну, собственно тут и ответ. Устройство не может отвечать так часто как может быть опрошено.
Стоит опрашивать реже, не все программисты настолько же профессиональны как разработчики Wiren board. Наши устройства утилизируют шину на 100%.

ADC · 04.Декабрь.2024 06:21:03

Но ведь modbus pool опрашивает без ошибок со скоростью 200мс.

BrainRoot · 04.Декабрь.2024 08:19:29

Нет, в цикле мы устанавливаем только время ожидания ответа (-o ), а запросы идут с максимальной частотой.
Если добавить в цикл ```read -t 0.2```` напимер (sleep работает только с целыми значениями) - то как раз воспроизведется задержка в 200мс.

ADC · 04.Декабрь.2024 10:58:16

В этом случае опрос получился более успешный, но все равно имеет место быть много пропусков:
