Опрос утсройств по rs-485

1

Добрый день.

Осуществляю тестирование своего ПО, для этого организовал одновременный обмен устройств по RS-485:
/dev/ttyNSC0 - модули ICP CON (7017 RC, 7041, 7063), протокол DCON, 9600 бод. Период опроса 1 сек.
/dev/ttyNSC0 - модуль DEP RTU3, протокол SYBUS, 38400 бод. Период опроса 1 сек. В процессе опроса часто меняется паритет порта, это особенность протокола.

Опрос, как говорилось, ведется одновременно. После каждого цикла опроса порт закрывается и открывается вновь с установкой всех его параметров. Аппаратное управление потоком, естественно, отключено.

Имеем следующую проблему. Периодически данные в порт (любой из двух) уходят, но назад или возвращаются частично, или не возвращаются вообще. Таймауты не спасают. При этом до устройств данные доходят, сами они ответ шлют (это я знаю точно, т.к. включался в разрыв линии PortMonitor’ом).

Получается, данные теряются уже на этапе чтения из порта самим контроллером. При этом, если запретить опрос по одному из портов, по другому порту обмен идет стабильно.

В консоли вижу следующее:

Прошу помочь. Это особенность работы кристалла или я что-то не то делаю?

Поправлюсь, порты все же разные, /dev/ttyNSC0 и /dev/ttyNSC1.

3

Я думаю, что это баг драйвера в ядре Linux, а вы всё делаете правильно. Мы уже один раз про такое слышали, но без подробностей и воспроизвести/локализовать не получилось.

Скажите, есть возможность предоставить какой-нибудь лог обмена данными по портам? Лучше мне на почту.

4

Да, я могу прислать лог обмена, если он чем-то поможет. Пришлю на почту, скорее всего, в пятницу или понедельник, внезапно заболел, так что сейчас сижу на больничном.

5

Пока полноценный лог собрать не удалось.
Однако, коллеги заметили интересный факт. Если в консоль начать выводить лог опроса устройств, опрос ухудшается. В частности, полностью перестает опрашиваться модуль RTU3 (в моем ПО это идентифицируется как таймаут по обмену, т.е. в порт ничего не вернулось). Может ли отладочный лог в консольный порт влиять на обмен по остальным портам? И как его выключить полностью? Пробовал в inittab комментировать getty, не помогает - в консольный порт данные все равно шлются (я имею в виду сообщения от sc16is7x2).

6

от sc16is7x2 сообщения выводятся только об открытии/закрытии порта, их, казалось бы, не должно быть много.

7

Ну вот те, что в первом сообщении, сгенерировались за 10 секунд. Не знаю, много это, или нет. Просто я к тому, если вывод в консольный порт перебивает обмен по остальным портам, это объясняет, почему у меня иногда приходят неполные кадры.

8

Ну конкретно сообщения вряд ли чему-то мешают, но это есть симптом большой проблемы. Вы похоже каждый раз при отправке сообщения открываете и конфигурируете порт, это естественно делается не очень быстро, потому что порт надо настроить.

Попробуйте открывать и настраивать порт только один раз, может быть станет лучше.

9

Не могу, к сожалению. Это идеальный случай - открыть порт один раз и настроить его.
На деле я могу (при очень большом желании) открывать порт один раз, но настраивать его придется часто, для каждого протокола, работающего с этим портом. Заказчики - народ экономный (мягко говоря), потому были проекты, где один ОВЕН ПЛК 100 с нашим ПО опрашивал по одному RS-485 порту устройства с протоколами Modbus, RSBus, нативный ОВЕН, Меркурий 230, Элтеко. Заметьте, все это на одном порту с постоянным закрытием/открытием порта и его настройкой.
Кроме того, SYBUS требует постоянной смены паритета, тут уже никуда не денешься.

Какого вида лог вам нужен, чтобы решить проблемы?

10

Попробовал добавить задержку 100 мсек после установки параметров порта, не помогло.
Похоже, что в момент установки параметров одного порта обмен по другому порту (или, возможно, лишь прием данных) блокируется.
Проверьте, пожалуйста, эту догадку. Вам для воспроизведения достаточно будет двух Modbus-устройств.

11

А попробуйте пожалуйста вот это ядро поставить: http://contactless.ru/share/linux-image-3.13.0-imxv5-x0.1_3.13-imxv5-x0.1+wb20141219072253_armel.deb , я там поправил в драйвере потенциально плохое место.

Самому к сожалению сейчас нет времени протестировать.

12

Добрый день.

Не знаю, возможно я сделал не совсем правильно. Получил следующее (Ethernet пропал, так что проверить обмен не могу):

Как правильно установить ядро?

13

надо было поставить сначала пакет wb-configs через apt-get, забыл написать.

Сейчас сделайте просто
ln -s -f /boot/vmlinuz-3.13.0-imxv5-x0.1 /boot/zImage
и всё должно заработать.

14

Так просто не получилось.
Раскатал образ заново, потом обновился целиком и поставил новое ядро.

Теперь обмен не идет вообще… В порт, похоже, уходит не то, что нужно. Посылки подозрительно короткие.

15

И не просто короткие, а мусор какой-то. Но всегда одинаковый. C0 1C и E0 1C. Я такие посылки не шлю.

16

Провел банальный эксперимент:

Alexey, прошу прощения, пока некогда посмотреть. Займусь в пятницу.

18

Хорошо, жду.

19

Чувствую, новогодний подарок мне не светит (.
Сегодня последний рабочий день в году, когда ответ ждать?

20

да, попытка сделать инициализацию порта быстрее не удалась.
Мы некоторое время назад озаботились переписыванием этого драйвера, первую рабочую версию мне обещали до конца праздников.
Как только она будет стабильно работать - отправим вам на тесты.

В общем я думаю, что в течение января вашу проблему (и все остальные с RS-485) решим.
