In a UDS session(diagnostic session ),aprogram application on a computer constitutes the client(within UDS, it is calledPCAN-UDSTester), the server is the ecu being tested and the diagnostic requests from client toserver are called services. The client always starts with a request and this ends with apositive or negative response from the server(ECuSince the transport protocol of UDS is done using ISo-TP, an international standardPCAN ISOTPfor sending data packets over a CAN Bus, the maximum data length that can betransmitted in a single data-block is 4095 bytes.PCAN-UDS API is an implementation of the Uds on CAN standard the physicalcommunication is carried out by PCAN-Hardware (PCAN-USB, PCAN-PCI etc )throughPCAN-Basithe pCAN-ISo-TP and PCAN-Basic API (free CAN APls from PEAK-System). Because ofthis it is necessary to have also the pCAN-1S0-tP and PCAN-Basic APls(PCAN-ISO-TP. dll and PCAN Basic. dll) present on the working computer where UdS is intended tobe used. PCAN-UDS, PCAN-ISO-TP and PCan-Basic apis are free and available for allFigure 1: Relationship of thepeople that acquire a pCAn-hardware2.2 Using PCAN-UDSSince PCAN-UDS API is built on top of the PCAN-1So-TP API and PCAN-Basic APls, it shares similar functions. Itoffers the possibility to use several PCAn-UDS (PUds) channels within the same application in an easy way. Thecommunication process is divided in 3 phases: initialization interaction and finalization of a puds-channelInitialization In order to do UDS on CAN communication using a channel, it is necessary to initialize it first. Thisis done by making a call to the function UDS_ Initialize (class- method: InitializePCAN-UDS APi- User ManualInteraction: After a successful initialization a channel is ready to communicate with the connected can bus.Further configuration is not needed the 24 functions starting with UDS Svc(class-methods: starting with Svccan be used to transmit UdS requests and the utility functions starting with Uds WaitFor(class- methodsstarting with WaitFor) are used to retrieve the results of a previous request. the Uds read and UDS Write(class-methods: Read and Write are lower level functions to read and write UDs messages from scratch. Ifdesired, extra configuration can be made to improve a communication session, like service request timeouts orISo-TP parametersFinalization: When the communication is finished, the function UDS_ Uninitialize(class-method: Uninitializeshould be called in order to release the puds-channel and the resources allocated for it. In this way thechannel is marked as free"and can be used from other applications23 FeaturesI mplementation of the UDS protocol(iSo 14229-1)for the communication with control unitsWindows DLLs for the development of 32-bit and 64-bit applicationsPhysical communication via Can using a Can interface of the pcan seriesUses the pcan-Basic programming interface to access the can hardware in the computerUses the pCAn-ISo-TP programming interface(iso 15765-2)for the transfer of data packages up to 4095bytes via the can bus2.4 System Requi rementsL- Windows 10, 8.1, 7(32/64-bitAt least 512 Mb ram and 1 GHz CPUPC CAN interface from peak-SystemPCAN-Basic APlL PCAN-SO-TP API2.5 Scope of supplyInterface DLL, examples, and header files for all common programming languagesDocumentation in pdf formatDocumentation in HTML Help formatPCAN-UDS APi- User Manual3 DLL API ReferenceThis section contains information about the data types (classes, structures, types, defines enumerations)andAPI functions which are contained in the pcan-uds api3.1 NamespacesPEAK offers the implementation of some specific programming interfaces as namespaces for the.

When increasing the frequency, inductive effects start to limit the currentand skin effect makes it increasingly difficult to resolve the current distribution in thewinding. At sufficiently high frequency, the current is mainly flowing in a thin layernear the conductor surface. When increasing the frequency further. capacitive effectscome into play and current is flowing across the winding as displacement currentdensity. When going through the resonance frequency, the device goes from behavingas an inductor to become predominantly capacitive. At the self resonance, the resistivelosses peak due to the large internal currents Figure 4 shows the surface current3 MODELING OF A 3D INDUCTORSolved with COMSOL Multiphysics 5.0distribution atl MHz.
