XCP UDP Configuration

Configure XCP UDP server connection

• 

Libraries:
Vehicle Network Toolbox / XCP Communication / UDP
Simulink Real-Time / XCP / UDP

Description

The XCP UDP Configuration block uses the parameters specified in the A2L file and the ASAP2 database to establish an XCP server connection.

Before you acquire or stimulate data, specify the A2L file to use in your XCP UDP Configuration. Use one XCP UDP Configuration to configure one server connection for data acquisition or stimulation. If you add XCP UDP Data Acquisition and XCP UDP Data Stimulation blocks, your model checks to see if there is a corresponding XCP UDP Configuration block. If there is no corresponding XCP UDP Configuration block, the model prompts you to add one.

The XCP UDP communication blocks support Simulink^® accelerator mode and rapid accelerator mode. You can speed up the execution of Simulink models by using these modes. For more information about these simulation modes, see Acceleration.

Parameters

Config name — Specify XCP UDP session name

'UDP_Config1' (default)

Specify a unique name for your XCP session.

A2L File — Select an A2L file

file name

Click Browse to select an A2L file for your XCP session.

Enable seed/key security — Select that key required to establish connection

off (default) | on

Select this option if your server requires a secure key to establish connection. Select a file that contains the seed/key definition to enable security. Note: Seed/key security is not support on Linux^® systems.

File (*.DLL) — Select file for seed and key security

file name

If you select Enable seed/key security, this field is enabled. Click Browse to select the file that contains the seed and key security algorithm that unlocks an XCP server module. This parameter is available in Windows Desktop Simulation for Vehicle Network Toolbox.

User-defined connect mode — Allow special connect mode

off (default) | on

Select this option to allow a special (user-defined) connect mode. When off, only a normal mode connection is supported.

Output connection status — Display connection status

off (default) | on

Select this option to display the status of the connection to the server module. Selecting this option adds a new output port.

Disable CTR error detection — Disable CTR error detection scheme

on (default) | off

To detect missing packets, the block can check the counter value in each XCP packet header. When on, counter error detection for packet headers is disabled. When off, the counter Error detection scheme is enabled.

Error detection scheme — Select CTR error detection scheme

One counter for all CTOs and DTOs (default) | Separate counters for (RES,ERR,EV,SERV) and (DAQ) | Separate counters for (RES,ERR), (EV,SERV) and (DAQ)

To detect missing packets, the block can check the counter value in each XCP packet header and apply an error-detection scheme.

Sample time — Sample time of block

-1 (default) | numeric

Enter the base sample time or a multiple of the base sample time. -1 means that sample time is inherited. For information about simulation sample timing, see What Is Sample Time?.

Local IP Address — Client IP address

x.x.x.x

Enter the IP address to which you want to connect.

Local Port — Client IP port

1–65535

The combination of Local IP address and Local port must be unique.

Ports in the range 5500 through 5560 are reserved for Simulink Real-Time communications.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

The XCP communication blocks support code generation with limited deployment portability that runs only on the host computer or Simulink Real-Time™ targets.

Code generation requires a C++ compiler that is compatible with the code generation target. For more information, see Supported and Compatible Compilers.

Version History

Introduced in R2019a

R2024b: New parameter: User-defined connect mode

The parameter User-defined connect mode allows a special connect mode.
