CAAPE Projects4. SECTION 4 – CAAPE PROJECTS4.1. OVERVIEW4.1.1. Projects and their LocationsA project is a collection of related CAAPE data, and is the top-level item handled byCAAPE. A project's data is stored in a number of files, some directly available to theuser and others only for internal use by CAAPE. The Project File (.cpb file) is the mainfile associated with the CAAPE program, describing the locations and relationships of allthe other files in the project. The scope of a project - how many systems at how manycustomer locations the project represents - is up to the user. Many projects can exist ona given PC, but CAAPE can only open one project at a time.All the files for a given CAAPE project are usually stored in a single directory on the PC.It is possible in some cases to have a CAAPE project refer to files outside its homedirectory, but care must be taken not to move, rename or delete the files or CAAPE isnot able to find them.4.1.2. Systems and ApplicationsProject data is organized into systems. A CAAPE system represents a set of hardwareconfigured for use at a particular customer location. Configuring the system involvesspecifying the hardware layout and how it is applied at the customer location. The userenteredconfiguration data is converted into data structures which are loaded into theprogram memory of the Vital and non-vital processor boards in the hardware to controltheir operation.The user programming for a given processor board in a hardware system is called anapplication. In CAAPE’s File View hierarchy, each system contains one or moreapplications. CAAPE shows the systems and their application files in a hierarchical(tree) arrangement, where the project is the top-level item that contains the systems andeach system contains application data. This arrangement is described in more detailwhen the contents of the Project Workspace are discussed.P2512A, Rev. Oct/09 4–1 Alstom Signaling Inc.
