EN-ICE 2

UAB: UNICOS Application Builder• Software factory used to develop UNICOS applications.

• Main features:• Provide a unified and highly customizable code generation

environment for PLC, SCADA and other UNICOS target platforms.

• Keep the internal UNICOS types and engineering/process knowledge separated from UAB to maximize reusability.

• Enforce input consistency and validity through automatic checking of syntax and grammar.

• Flexibility: Easy to adapt the framework for new UNICOS packages.

• Scalability: Modular architecture based on plug-ins.

UAB Modular ArchitectureUAB Core

• Common utilities required by most of the plug-ins (user report, logging, …).• Dynamically discovering the different plug-ins.• Load the UNICOS project data.• Connect plug-ins with external files (specs, device type definitions, …).

UAB Plug-ins• Platform dependent (Siemens, Schneider, WinCC O. A., …).• The plug-ins define the structure and format of the generated files (XML, SCL, …).

UAB Resources• Set of resources required by the plug-ins.

(Device Type Definitions, Jython Templates…).

UAB Components• Logical integration of UAB plug-ins.• Friendly user interface (Wizard).• Detected by installation and update

tool (UAB Bootstrap).

UAB Plug-ins

Features• Platform dependent (Siemens, Schneider, WinCC O. A., …).• The plug-ins define the structure and format of the generated files (XML, SCL, …).

Generation Workflow1. Get the required parameters and data sources (specs file, templates location,

output folder and output file(s) location).2. Process the selected templates (global templates, device type templates, post-

process templates).3. Write the output files with the data provided by the templates.

Reusability• In some cases it is possible to reuse the same plug-in for different target

platforms (when the plug-in functionalities are equal or very similar).• Example: The CPC Touch Panel generator is used for several targets: Magelis, TIA

Portal and WinCCFlexible.

Jython TemplatesFeatures

• The templates are specialized scripts used to generate code for the target platform.

• The templates are located in the Resources Package (separated from the plug-ins).

Different Nature• Device Type Templates: Generate code related to an specific

device type. One template for each existing device type.• Global Templates: Used to generate code not related to the

device types (like front-end configuration).• Semantic Rules: Used to validate the user inputs. These

templates are shared by all the plug-ins.

Device Type Templates

11/02/2014

• Development for EPICS target platform:• Try to reuse the existing plug-ins and device type templates (WinCC OA).• Create a new CPC application using the CPC Wizard and resources package (v1.6.0)• Modify the WinCCOA device type templates in the application folder to generate the

required output for EPICS.• If the generated file is plain-text (comma separated or similar) Modification is straightforward.• If the generated file is xml Use a different API to create the files (IOutputFileBuffers @see

Javadoc for UAB Core v1.5.2)
