Important information before getting startedCANalyzer versus CANoeCANalyzer is wholly contained within isEthernetMOSTFlexRayLINCANCANoe offers significant additional capability beyond CANalyzer to: Stimulate the network(s) with Interaction Layer knowledge Run automated tests and generate test reports Implement automated diagnostic tests3
Important information before getting startedCANoe and the added value of the Interaction Layeruuu4The CANoe Interaction Layer (in short CANoeIL): Provides a signal-oriented means of accessing the bus Map signals to their appropriate send messages Controls the sending of these messages as a function of the (OEM) Send ModelTransmission of messages and signals is described based on attributes in the databaseCANoeIL models the transmission behavior at run-time using those attributes
Important information before getting startedOverview of CANalyzer variantsCAPL is available in CANalyzer PRO and all versions of CANoeCANalyzer is available in three different variants:uPRO: Professional variant: full functionalityuEXP: Expert variant: supports all applications up tocomplex analysis of heterogeneous systems; doesnot support CAPL programsuFUN: Fundamental variant: simple applications, does notsupport CAPL, diagnostic tester and panelsDetailed information about the variants of CANalyzer is available at ourwebsite: http://www.vector.com/vi canalyzer variants en.html5

Visual Sequencer (GUI based programming (Subset of CAPL))GeneralAvailable in both CANalyzer PRO and EXP Intended to allow some automation within the EXP variantThe Visual Sequencer allows you to create automated command sequenceswith the purpose of Stimulating the networkControlling applicationsIn order to structure the individual steps, loops and conditional commandblocks can be used, such as if, else if, end ifEach sequence is shown in a separate window, and can be edited at anytime, even while a measurement is running.7

Brief Introduction to CAPLGeneralFunctional blocks based on CAPL (Communication Access ProgrammingLanguage) can be created to programu Network node modulesu Special evaluation programs for individual applicationsSome CAPL characteristics:u C-like programming languageu Event based, not interrupt drivenu CAPL programs are created using an integrated developmentenvironment called the CAPL Browseru Direct access to signals, system variables and diagnostic parametersu Able to link user created DLLs11

Brief Introduction to CAPLCompilinguIn order to generate an executable program file from a CAPL program,the program must be compiled with the CAPL ndow:When you double-click the error description, the cursor in the TextEditor automatically jumps to the point in the source code, where theerror originated.15
Brief Introduction to CAPLExamining a CAPL programAdditional CAPL files that contain generic codethat can be reused in other programsVariables defined here are accessiblethroughout the CAPL programMultiple pre-defined event handlers exist foryour use within CAPL. The code in this handlerwill only be executed when the event occurs.You can create your own functions (specialhandler) that contain related code to beexecuted frequently16
Brief Introduction to CAPLAdding an Event HandlerCAPL is a procedural language in which the execution of program blocks iscontrolled by events. These program blocks are referred to as eventprocedures.17
