6.10.1 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:
1. Target Platform
2. Memory Layout
3. General
4. Networkfunctionality
5. 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.
6.11 Parameter Manager
TheParameter Manager is a a target specific component component of the CoDeSys programming
system and must be activated in the target settings. (siehe Kap. ).
The Parameter Manager can be used to make variables of a CoDeSys IEC-program, constant
parameters or specific system parameters accessible to all CoDeSys compatible systems in a network
for the purpose of data exchange, typically via fieldbus. For this purpose in the editor you can create
parameter lists and load down to and up from the runtime system.
What are Parameters :
In this context parameters are:
• process variables of the CoDeSys IEC project
• process independent parameters
• specific system parameters, predefined by the target system
• functionblock instances or structure variables, arrays
Each parameter is identified by a certain set of attributes like e.g.'default value', 'access rights', and
especially by an unique access key ('Index', 'SubIndex', 'Name'), which can be addressed for reading
or writing data from/to the parameter list. This data exchange can be done via communication
services and it is not necessary to know any addresses of variables or to provide any extra functions.
So the use of the Parameter Manager functionality it is an alternative to using Network Variables.
What are Parameter Lists:
Parameter lists are used for organizing the parameters and can be saved with the project and loaded
to the local target system which is controlled by the corresponding IEC-program. For each type of
parameters there is a corresponding type of parameter list.
