Common simulation windows
Bus simulation is one of the most important features of ETStudio, and users can set the properties, initial values, and status of the simulation network through a specific simulation window.
UDS Setup Window In the UDS Setup window, all networks, devices, and network nodes are displayed graphically, as shown in the image. In the system view on the left side of this window, you can modify the simulation settings (such as importing DBC files, adding networks, adding channels, etc.), and in the grid view on the right, you can set up, activate, and script the ECU. The UDS Setup window is one of the most commonly used windows to simulate the basic transmission behavior of software components and control units that may occur in a real control unit.
Common diagnostic windows
ETStudio can support powerful diagnostic functions, when users import diagnostic profiles, ETStudio will automatically generate diagnostic test windows for users based on the profile
UDS Dashboard Window
The UDS Dashboard window allows you to send a single diagnostic request to the ECU, receive and analyze the diagnostic response returned by the ECU, as shown in the figure.
DTC Window The DTC window can read out a list of all DTCs (Diagnostics Trouble Codes) of an ECU, as shown in the figure, and the user can delete the fault codes in the list one by one. In order to read out the DTC list, the relevant diagnostic profile file (e.g. CDD, ODX, or MDX) must be loaded
