General1. SECTION 1 – GENERALThis manual contains the basic information needed to understand how to use Alstom’sComputer-Aided Application Programming Environment software package (referred toas either <strong>CAAPE</strong> or the <strong>CAAPE</strong>).1.1. SAFETY<strong>CAAPE</strong> software can be used to process a set of equations to develop a fail-safesystem.WARNINGNO USER MODIFICATION OF <strong>CAAPE</strong> OR ANY OF ITS COMPONENTPROGRAMS IS ALLOWED BECAUSE ANY PROGRAM CHANGECOULD COMPROMISE THE SAFETY PERFORMANCE OF THESYSTEM.The responsibility for the underlying safety of the Vital logic equations and other Vitalapplication data belongs to the user. The user is responsible for verifying that theinterlocking control equations developed by the program correctly specify the intendedoperation in a fail-safe manner.1.2. INTENDED AUDIENCEThis manual is written for signaling application engineers and others who wish tounderstand the basic operation of <strong>CAAPE</strong>.Before reading this manual you should have a working knowledge of using the MicrosoftWindows ® operating system and running programs in that environment.1.3. ABOUT THIS MANUALThis <strong>CAAPE</strong> User’s <strong>Manual</strong> describes basic <strong>CAAPE</strong> operation. See the VPI andCenTraCode II-s CAA Reference <strong>Manual</strong>s for specific application rules, text recordformats, etc.WIU is a version of VPI ® that was developed on a modified hardware platform for aspecific project. The procedures for programming WIU applications are very similar tothose for VPI with the exception of some terminology such as board and applicationtype names. This manual, therefore, generally does not describe WIU in detail.Similarly, iVPI is a newer version of VPI on a different hardware platform. The genericterm “VPI” is used to refer to both the original VPI and the newer iVPI, except wheretheir features diverge.P2512A, Rev. Oct/09 1–1 Alstom <strong>Signaling</strong> <strong>Inc</strong>.
