Назначение.

Программный модуль MCX “Monitor Module” предназначен для построения на его базе систем удалённого мониторинга и автоматизации контроля технологического процесса, водотеплоснабжения для центральных тепловых пунктов, систем диспетчерского контроля. Модуль осуществляет автоматическое измерение и индикацию значений параметров систем теплоснабжения и водоснабжения (горячего и холодного), телеметрический контроль и сбор данных по информационным сетям.
Особенности модуля:

Таблица 1. Перечень функций и особенностей модуля мониторинга.

№ п.п. Описание функционала и особенностей модуля.
1 Простотой: возможно подключение оборудования, соответствующего конфигурации входов по умолчанию, к контроллеру без каких-либо дополнительных настроек (см. п.3).
2 Удобный: в случае неподходящей конфигурации (по умолчанию) входов контроллера к подключаемому оборудованию (тип датчика, например), можно легко внести изменения в конфигурацию с помощью дисплея контроллера (см. п.1, п.4.1).

На главном экране отображаются состояния входов и выходов контроллера (см. п. 2.2).

Поддержка меню контроллера двух языков: русский и английский.
3 Универсальный: нет жёсткой привязки конфигурации входов контроллера к конкретному оборудованию: в наименованиях сконфигурированных входов контроллера нет принадлежности к определённому виду устройств.

Может использоваться в любых управляемых системах, организованных в сеть Modbus.
4 Необходимый в системах с большим количеством устройств: является блоком с дополнительными входами для подключения в управляемую систему дискретных и аналоговых устройств.
5 Со встроенной системой анализа состояния аналоговых устройств: отслеживание аварий устройств на аналоговых входах и звуковое оповещение при их возникновении.
6 Открытый: с помощью протокола Modbus возможно считывание необходимой информации с модуля, а также удалённое изменение настраиваемых параметров.

Идентификационные параметры модуля.

Таблица 2. Перечень идентификационных параметров модуля.

№ п.п. Наименование параметра Mobus адрес Значение
1 Код продукта (контроллера) 100 в зависимости от контроллера
2 Серийный номер контроллера 102 в зависимости от контроллера
3 Код БИОС 104 в зависимости от прошивки контроллера
4 Код приложения 106 2
5 Версия приложения 108 Начиная с 1.00
  1. Технические характеристики контроллера.

Программный модуль MCX “CWS” разработан для контроллеров Данфосс серии MCX. Базовым контроллером является MCX06D.

Контроллер MCX имеет два интерфейса, позволяющих подключить внешние устройства по сети:

CAN, для подключения устройств по локальной сети CANbus;

RS485, для подключения устройств по сети Modbus (протокол связи Mobus RTU).

Рисунок 1. Внешний вид контроллера Danfoss MCX06D.

Основные технические характеристики контроллера:

Напряжение питания =20-60 В, ≈24 В ±15% 50/60 Гц;

Потребляемая мощность 9 ВА;

Изоляция между цепями питания и цепями управления.
