Библиотека низкоуровневых сенсоров и чипов 1.4 GPLv2 OscadaLibs.db (SQL, GZip) > DAQ.tmplb_LowDevLib en, uk, ru Роман Савоченко

Библиотека шаблонов предоставления доступа к данным устройств низкоуровневых шин.
- комбинировать 1W шаблоны в одном сложном и дополнить 1W работой непосредственно через GPIO.

Библиотека устройств пользовательских протоколов создана для предоставления доступа к данным устройств низкоуровневых шин, с протоколом достаточно простым для реализации в модуле пользовательского протокола или непосредственно на внутреннем языке подобном на Java.

Названия элементов и их параметров доступны на языках: Английский, Украинский и Российский. Их исходный код написан в языко(человеческий)-независимом режиме с вызовом функции перевода tr() и перевод этих сообщений также доступен Английским, Украинским и Российским.

Для подключения библиотеки к проекту станции OpenSCADA Вы можете получить файл БД как:

  • такой что поставляется с готовым и соответствующим пакетом дистрибутива Linux вроде "openscada-libdb-main", "openscada-LibDB.Main";
  • наиболее актуальный и непосредственно полученный из репозитория subversion, преобразованный в файл БД SQLite путём:
$ wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/OscadaLibs.sql
$ sqlite3 -init OscadaLibs.sql OscadaLibs.db .exit

Этот загруженный файл вы далее можете разместить в каталоге проекта станции и создать объект базы данных модуля БД "SQLite", зарегистрировав файл базы данных в конфигурации.

Для DAQ-шаблонов, в целом, вам нужно создать представительский объект устройства в модуле Логического Уровня и выбрать соответствующий шаблон из библиотеки шаблонов. Далее, для корректной конфигурации, придерживайтесь специфики шаблона в персональном описании. Концепцию доступа к данным через пользовательский протокол можно изобразить как на рисунке 1.

Рис.1. Концепция доступа к данным через пользовательский протокол.

Как можно видеть с рисунка 1, взаимодействие с устройством происходит через некоторый транспорт на котором они физически базируются. Запрос к транспорту Вы можете отправить:

  1. Непосредственно с помощью функции системного API OpenSCADA объекта транспорта string messIO( string mess, real timeOut = 0 );, если протоколоспецифическая часть очень проста и данные Вам нужно лишь извлечь.
  2. Завёрнутый запрос данных req, функцией int messIO( XMLNodeObj req, string prt ); и для протокола prt, если протокольная часть достаточно сложная и уже представлена в OpenSCADA.
  3. Завёрнутый запрос данных специфический к пользователю с помощью функции int messIO( XMLNodeObj req, "UserProtocol" ); и реализации пользовательского протокола, если протокольная часть достаточно сложная и ещё отсутствует в OpenSCADA. Пользователь реализует тут саму протоколоспецифическую часть в модуле UserProtocol и часть специфическую к данным в шаблоне для модуля Логического Уровня или непосредственно в процедуре контролера на внутреннем языке программирования модуля JavaLikeCalc.
At.png Этот последний метод развит к возможности формирования протокольной части кода непосредственно в том-же коде шаблона, как отдельная встроенная функция через вызовом функции запроса первого метода, если нет необходимости повторного использования, или даже если такая необходимость есть и тут имеет смысл создание комплексного шаблона, который сможет объединять роль и выходного протокола, через его подключение также к модулю пользовательского протокола. И оно будет полностью храниться в одной библиотеке шаблонов.

At.png Прямая работа с выходным транспортом функции string messIO( string mess, real timeOut = 0 ); не предусматривает блокирования транспорта поза вызовом этой функции, а соответственно, для сложных протоколов с посылками ответа более чем в одном пакете, что предусматривает процесс "дожидания", не можно использовать общий транспорт, по которому возможна отправка пакетов различных протоколов или даже один, но в различных задачах (объектах контроллеров). Соответственно, если есть необходимость использования совместного транспорта, то размещайте параметры опроса по протоколу в одном объекте контроллера (задаче) или используйте модуль пользовательского протокола, к которому это замечание не имеет отношения, поскольку он осуществляет такое блокирование на время вызова процедуры обработки, как и остальные модульные протоколы OpenSCADA. Для размещения реализации протокола тут вы должны выполнить и придерживаться приведенных требований:

  • быть владельцем прав или автором кода и распространять его под любой свободной лицензией, предпочтение предоставляется GPL;
  • приготовить и сохранить в отдельном файле БД SQLite, или как текстовый файл, на предмет: описания параметров (ВВ), кода процедуры написанного и отформатированного согласно какой нидудь системы;
  • написать краткое описание и инструкцию подключения устройства по протоколу в способ похожий на другие тут;
  • написать прямой запрос в тему форума "Разработка OpenSCADA" на предмет размещения протокола тут, включая доказательства его работоспособности от любого разработчика OpenSCADA или краткое демонстрационное видео.

3. Create a logical parameter object and select the template for that, one for each sensor. Enable the parameter.
4. Into the tab "Template configuration" of the logical parameter object you need to set:
  • transport — to address of the "BCM 2835" parameter like to "DAQ.GPIO.io.pi" or to address of the transport into step 1; tracing for the address changing is supported;
  • addr — the I2C slave device's address [0...119];
  • RS, E, D4, D5, D6, D7 — numbers of the GPIO pins where connected the proper data ones of the sensor.
5. Result: The logical parameter object will perform interaction and setting lines' values to the display.
