Command Load core dump

Function: TwinCAT searches the project directory for core dump files.

• If TwinCAT finds a core dump file in the project directory, you are asked whether you want to load this core dump or browse for a dump file.
• If TwinCAT does not find a core dump file in the project directory, you can browse for another dump file.

Loading into the project causes an online view of the PLC project to appear, with the state the PLC project had at the time when the core dump was created. You can view the variable values contained in it. The call tree is also available.

Call: Menu PLC > Core dump

Requirement: The application is in offline mode.

The Core Dump view can only be closed again using the Command Close core dump command. The Logout command is not effective in this view.

Core dump usable only with associated compile info file If you archive or save a core dump file, please note that the associated project and associated compile info file (*.compileinfo file, which is stored, for example when creating the project, in the "_CompileInfo" folder) must be present in order to load a core dump. If this is not the case, TwinCAT cannot use the dump later. Please also note here the setting options on the Settings tab. With the help of the Core Dump setting, you can configure whether the core dump file, which may be located in the project directory, is to be saved together with the available compile info files in a TwinCAT file archive.
