6 - The Resources
A *.mon-file can be created by using command 'Save to file'.
Note: Regard the alternative way of saving a trace by using the commands of menu 'Extras' 'Save trace
values'.
'Load from controller'
With this command the trace (configuration + values) which is currently used on the controller can be
loaded to the CoDeSys project. It will be displayed in the trace window and can be set as active
project trace configuration.
'Set as project configuration'
With this command the trace configuration which is currently selected in the list of available traces
(field 'Trace' in the trace window) can be set as active configuration within the project. The selection
list besides the currently used (top position) offers all traces which have been loaded to the project by
command 'Load from file' from *.mon-files (e.g. for the purpose of viewing).
6.10 Target Settings
The "Target Settings" is an object of the 'Resources'. Here you define, which target shall be used for
the project and how it will be configured. If a new project is started with 'Project' 'New', a dialog will
open where the target, that means a predefined configuration for a target, has to be set.
The list of available targets depends on which Target Support Packages (TSP) are installed on the
computer. These describe platform specific basic configurations and also define, to which extent the
configuration can be modified by the user in the CoDeSys Target settings dialogs.
Please regard: If no TSP is available, only the setting 'None' will be offered in the target system selection box.
This will switch to simulation mode automatically and no configuration settings will be possible.
Target-Support-Package
A Target Support Package (TSP) must be installed before starting by the aid of the installation
program InstallTarget which might be part of the CoDeSys-Setup.
A Target Support Package (TSP) contains all the files and configuration information necessary to
control a standard platform with a program created in CoDeSys. What has to be configured:
codegenerator, memory layout, PLC functionality, I/O modules. In addition libraries, gateway drivers,
ini-files for error messaging and PLC browser have to be linked. The central component of a TSP is
one or more Target files. A Target file directs to the files which are in addition necessary to configure
the target. It is possible that several target files share these additional files.
The default extension for a Target file is *.trg, the format is binary. Additive definitions are attached to
the entries in the target file which determine whether the user can see and edit the settings in the
CoDeSys dialogs.
During installation of a TSP the target file for each target is put to a separate directory and the path is
registered. The associated files are copied to the computer according to the information of a Info file
*.tnf . The name of the target directory is the same as the targets name. It is recommended to store
the target specific files in a directory which is named with the manufacturers name.
The files which get installed with a TSP are read when CoDeSys is started. The target settings which
are done in the CoDeSys dialogs will be saved with the project.
Please Note: If you use a new target file or if you have changed the existing one, CoDeSys has to be restarted
to read the updated version.
