Address Space Prototyping Tool (asp.exe)
The OPC UA Address Space Prototyping (asp.exe) is an engineering tool and can be utilized in several ways:
creates
UA Address Spacepopulated using input XML files compliant with theUANodeSetschema defined in Part 6 Annex F.validates an instance of the
UA Address Spaceagainst the OPC UA specification 1.04.exports XML file compliant with the
ModelDesignschema that may be used as the input for the OPCFoundation/UA-ModelCompiler.
These instructions will get you a copy of the software up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
asp { filePath } [(-e | --export=)filePath] [ (-s | --stylesheet=)stylesheetName ] [ (-n | --namespace=)ns ] [ --nologo ]
asp [ --help ] [ --version ]
asp [ help ] [ version ]
Argument | Description |
filePath | Specifies the input file to populate the internal |
Option | Description |
| Displays command syntax and options for the tool. It halts processing and displays the help screen. The help screen is also displayed when the parsing process fails, along with the clear and explicit description of every error encountered. The switch or the built-in |
| Prints version information. The switch or the built-in |
| Suppresses the banner. |
Option | Description |
| Specifies the output file containing the ModelDesign XML document. |
| Name of the stylesheet document (XSLT - eXtensible Stylesheet Language Transformations). With XSLT you can transform an XML document into any text document. |
| Specifies the namespace for the generated types. If not specified last imported model is used for export. |
The following table describes the notation used to indicate command-line syntax.
Notation | Description |
Text without brackets or braces | Items you must type as shown |
Text Italic | Placeholder for which you must supply a value |
[Text inside square brackets] | Optional items |
{Text inside braces} | Items that can be repeated |
Vertical bar | Separator for mutually exclusive items; choose one |
The current binary release containing ready to use application is available on the repository Releases page. Download and run the file to unzip the content to the selected folder. Now you may run the application file asp.exe. The section Examples cover details on how to get started using attached examples.
The application is located on the GitHub at OPC-UA-OOI and maintained as the project
There are the following Windows Command shell scripts attached to the software and located in the main folder where the downloaded file has been unzipped:
DoDisplayHelp.cmd- displays a help screen and version informationDoValidate.cmd- validates theUA Address Spacecontent populated using theXMLModels\DataTypeTest.NodeSet2.xmlXML documentDoExport.cmd- validates theUA Address Spacepopulated as above and exports the model to theXMLModels\DataTypeTest.ModelDesign.xml
NOTE: The folder
XMLModelsalso contains an exampleDataTypeTest.NodeSet2.xmlXML document compliant withUANodeSetused by above-mentioned scripts. For your convenience, the folder also contains relevant schema files.
Run the script DoDisplayHelp.cmd or enter the following command
asp --help --version
It allows you to display a help screen and version information. A similar screen is used to report syntax errors to the end user.
Run the script DoValidate.cmd or enter the following command
asp "XMLModels\DataTypeTest.NodeSet2.xml"
The screen will contain a verbose listing of diagnostic messages related to the processing of the input file DataTypeTest.NodeSet2.xml The messages can be examined to improve the files used to populate the UA Address Space and remove any inconsistency against the OPC UA Specification 1.04.
Run the script DoExport.cmd or enter a similar command to the following one
asp "XMLModels\DataTypeTest.NodeSet2.xml" -e "XMLModels\DataTypeTest.ModelDesign.xml" -s XMLstylesheet
The screen will contain a verbose listing of diagnostic messages related to the processing of the input file - DataTypeTest.NodeSet2.xml in this example. All inconsistency problems will be fixed on a best-effort attempt basis. Finally, the model will be exported to the file XMLModels\DataTypeTest.ModelDesign.xml.
The model contains the XSLT instruction
<?xml-stylesheet type="text/xsl" href="XMLstylesheet"?>
to transform XML documents into other formats (like transforming XML into HTML, PDF, mark-down, etc).
XSL (eXtensible Stylesheet Language) is a styling language for XML.
XSLT stands for XSL Transformations.
