<h1>Rapid Gate Module</h1> | ||
<h2>Overview</h2> | ||
<p>Rapid Gate Module is designed to synchronize data between several Rapid SCADA instances. The module allows to setup a backup server, as well as provides data transfer from SCADA installed on remote locations to the primary SCADA.</p> | ||
|
||
<h2>Installation</h2> | ||
<p>Rapid Gate Module is installed in accordance with <a href="../installation-and-run/module-installation.html#modules">the general sequence of installing Server modules</a>. The module library file is ModRapidGate.dll. After adding the module, you need to perform several additional actions:</p> | ||
<ol> | ||
<li>Open the module log C:\SCADA\ScadaServer\Log\ModRapidGate.log in a text editor and copy a computer code.</li> | ||
<li>Register the module by contacting the developers or using <a href="http://trial.rapidscada.net/?prod=ModRapidGate" target="_blank">the trial key generator</a>. A register key must be stored in C:\SCADA\ScadaServer\Config\ModRapidGate_Reg.xml between RegKey tags.</li> | ||
<li>Configure the module (see the section below).</li> | ||
<li>Restart the Server service by clicking <img src="../../common-images/restart.png" />.</li> | ||
</ol> | ||
|
||
<h2>Configuring</h2> | ||
<p>To cofigure Rapid Gate Module, edit C:\SCADA\ScadaServer\Config\ModRapidGate.xml using a text editor. The settings contains the connection parameters for the SCADA server (target server) to which data are transferred and from which commands are received.</p> | ||
<p>Note that you usually need to configure the firewall on the target server to allow connections with it over the network.</p> | ||
|
||
<h2>Algorithm</h2> | ||
<p>The algorithm of Rapid Gate Module has the following features:</p> | ||
<ol> | ||
<li>The module transmits only the data that are received from Communicator. The values of the calculated input channels are not transmitted.</li> | ||
<li>The data is transmitted to the same input channel numbers to which they are received.</li> | ||
<li>The transmitted values are already calculated by the formulas of the input channels, which can result in double applying of the formulas on the target server. Therefore, when using the module, it is recommended that calculations be performed in separate input channels of the calculated type.</li> | ||
<li>The module has a data transfer queue, which allows restoring data in case of a short-term connection failure with a target server.</li> | ||
</ol> | ||

<title>Модуль Быстрый шлюз - Документация Rapid SCADA</title> | ||
<meta charset="utf-8" /> | ||
<link href="../../../css/scadadoc.min.css" rel="stylesheet" type="text/css" /> | ||

<h1>Модуль Быстрый шлюз</h1> | ||
<h2>Обзор</h2> | ||
<p>Модуль Быстрый шлюз предназначен для синхронизации данных между несколькими экземплярами Rapid SCADA. Модуль позволяет организовать работу резервного сервера, а также обеспечивает передачу данных от SCADA, установленных на удалённых объектах, на главную SCADA.</p> | ||
|
||
<h2>Установка</h2> | ||
<p>Модуль автоматического управления устанавливается в соответствии с <a href="../installation-and-run/module-installation.html#modules">общей последовательностью установки модулей Сервера</a>. Файл библиотеки модуля - ModRapidGate.dll. После подключения модуля необходимо выполнить несколько дополнительных действий:</p> | ||
<ol> | ||
<li>Открыть журнал работы модуля C:\SCADA\ScadaServer\Log\ModRapidGate.log в текстовом редакторе и скопировать код компьютера. </li> | ||
<li>Зарегистрировать модуль, связавшись с разработчиками или с помощью <a href="http://trial.rapidscada.net/?prod=ModRapidGate&lang=ru" target="_blank">сервиса генерации демо-ключей</a>. Регистрационный ключ сохраняется в файле C:\SCADA\ScadaServer\Config\ModRapidGate_Reg.xml между тегами RegKey.</li> | ||
<li>Сконфигурировать модуль (см. ниже).</li> | ||
<li>Перезапустить службу Сервера с помощью кнопки <img src="../../common-images/restart.png" />.</li> | ||
</ol> | ||
|
||
<h2>Конфигурирование</h2> | ||
<p>Чтобы сконфигурировать модуль Быстрый шлюз, необходимо отредактировать файл C:\SCADA\ScadaServer\Config\ModRapidGate.xml с помощью текстового редактора. В настройках указываются параметры подключения к тому cерверу SCADA (целевому серверу), на который будут передаваться данные и с которого будут приниматься команды ТУ.</p> | ||
<p>Обратите внимание, что на целевом сервере обычно небходимо настроить брандмауэр, чтобы разрешить подключение к нему по сети.</p> | ||
|
||
<h2>Алгоритм работы</h2> | ||
<p>Алгоритм работы модуля Быстрый шлюз имеет следующие функциональные особенности:</p> | ||
<ol> | ||
<li>Модуль передаёт только те данные, которые поступают от Коммуникатора. Значения дорасчётных входных каналов не передаются.</li> | ||
<li>Данные передаются на те же номера входных каналов, на которые они были получены.</li> | ||
<li>Передаваемые значения уже посчитаны по формулам входных каналов, что может привести в двойному применению формул на целевом сервере. Поэтому при использовании модуля рекомендуется вычисления по формулам выполнять в отдельных дорасчётных входных каналах.</li> | ||
<li>Модуль имеет очередь передачи данных, что позволяет восстанавливать данные при кратковременном обрыве соединения с целевым сервером.</li> | ||
</ol> | ||
