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.
6.6.1 Dialog Target Settings
The dialog Target Settings will open automatically, when a new project is created. It also can be
opened by selecting the menu item 'Target Settings' in the register 'Resources' in the Object
Organizer.
Choose one of the target configurations offered at Configuration.
If no Target Support Package has been installed, only 'None' can be selected, which means working
in simulation mode. If you choose one of the installed configurations it depends on the entries in the
target files, which possibilities are left to customize this configuration in the CoDeSys dialogs. If you
choose a target configuration, for which there exists no valid licence on the computer, CoDeSys asks
you to choose another target.
If a configuration is selected, which is provided with the entry "HideSettings" in the corresponding
target file, you only can see the name of the configuration. Otherwise there are five dialogs available
to modify the given configuration:
5. Target Platform
6. Memory Layout
7. General
8. Networkfunctionality
9. Visualization
Attention !: Please be aware, that each modification of the predefined target configuration can cause severe
changes in performance and behaviour of the target !
Press if you want to reset the target settings to the standard configuration given by the
target file.
