4.10. Configuration file of the OpenSCADA and parameters of command-line OpenSCADA execution.

Configuration file of the OpenSCADA system is provided to store the system and general configuration of OpenSCADA-station. Only in the configuration file and through the command-line options you can specify the part of the key system parameters of the station, so familiarity with the structure of the configuration file is necessary for professionals who make solutions based on OpenSCADA.

The configuration file of the OpenSCADA system can be called somehow, but the oscada.xml name and derived from it are accepted. The configuration file is usually indicated when you start the station by the command-line option --Config=/home/roman/roman/work/OScadaD/etc/oscada_demo.xml. For the convenience of the calling the startup scripts of the station are created with the correct configuration file, for example script (openscada_demo) of the demo station execution:


#!/bin/sh
openscada --Config=/etc/oscada_demo.xml $@

If the configuration file is not specified then the standard configuration file: /etc/oscada.xml is used.

Structure of the configuration file based on the extensible markup language XML. Therefore the strict adherence to the rules of XML syntax is required. An example of the configuration file of the OpenSCADA, with configuration nodes of most of the OpenASCADA components, is given below:

<?xml version="1.0" encoding="UTF-8" ?>
<OpenSCADA>
    <!--
    This is the OpenSCADA configuration file.
    -->
    <station id="DemoStation">
        <!--
        Discribe internal parameter for station.

</OpenSCADA>

Lets examine in details the structure of the configuration file. A configuration file can contain a configuration of several stations in the sections <station id="DemoStation"/>. To attribute set the identifier of the station. Using one or another section of the station at startup is specified by the command-line option --Station=DemoStation. Section of the station directly contains parameters of the station and subsystems' sections. Configuration options of the section are written in the form <prm id="StName">Demo station</prm>. Where in the attribute <id> the ID of the attribute is specified, and in the tag's body the value of parameter "Demo station" is specified. The list of available options and their description for the station and all other sections can be obtained from the console by calling OpenSCADA with parameter --help or in the "Help" tabs of the pages of the components of the configuration files of OpenSCADA (Fig.4.10a).

The "Help" tab of the OpenSCADA component. (85 Kb)

Sections of subsystem (<node id="sub_DAQ" />) contains parameters of subsystem, sections of modules and sections of tables of reflections of the data of databases in the configuration file. Sections of modules (<node id="mod_DiamondBoards" />) contain the individual parameters of modules and sections of tables of reflection of the data of databases in the configuration file.

Sections of the tables of reflection of the data of databases are provided for placement in the configuration file records of DB tables for the OpenSCADA components. Lets examine the table of incoming transports "Transport_in" of subsystem transports (<node id="sub_Transport">) from the example of configuration file above. The table contains two records with fields: ID, MODULE, NAME, DESCRIPT, ADDR, PROT, START. After booting with this section and in general without the DB in the subsystem "Transports" of the "Sockets" module you'll see two input transports. Formats of the table's structures of the main components are included in the demo configuration files. For the details of the database's structure you should read the relevant documentation of modules or simple save the object into the configuration file.
