SystemLog

Get current console log from target computer

Description

A SystemLog object represents the console log from the target computer at the time that the object is created by the slrealtime.SystemLog function.

Creation

slog_object = slrealtime.SystemLog(target_object) creates a system log object that contains a table of current target computer console messages in its messages property.

To view the target computer console log, create a SystemLog object and view its messages property or use the Simulink® Real-Time™ system log viewer slrtLogViewer.

Properties

expand all

The messages property value is a table of the current console log messages.

Object Functions

slrtLogViewerOpen the Simulink Real-Time System Log Viewer tab in the Simulink Real-Time Explorer to view the console log from the target computer

Examples

To work with multiple target computers, make the computer names available by using a targets object.

Create targets object my_tgs. Add target computers to the targets object. Assign target computers to target objects. Create target settings object and list the target computer names.

  1. To use the custom message functions in an S-function, include the header file. Place an ifndef statement around the include.

    #ifdef SIMULINK_REAL_TIME
    #include "slrt_log.hpp"
    #endif
  2. In an S-function, place an ifndef around the function call.

    #ifdef SIMULINK_REAL_TIME
    slrealtime::log_error("Some custom message.");
    #endif
  3. Call the function for the selected severity level.

    slrealtime::log_trace("Some custom message.");

    or

    slrealtime::log_debug("Some custom message.");

    or

    slrealtime::log_info("Some custom message.");

    or

    slrealtime::log_warning("Some custom message.");

    or

    slrealtime::log_error("Some custom message.");

    or

    slrealtime::log_fatal("Some custom message.");
