6.13.3 Deleting connections
There are a number of possibilities for removing the connection between the output of an element E1
and the input of an element E2:
Select the output of element E1 and press the key or execute the command 'Edit' 'Delete'.
Several connections will be removed at the same if the output of E1 is connected to more than one of
inputs.
Select the input of element E2 and press the key or execute the command 'Edit' 'Delete'.
Select the input of E2 with the mouse, hold the left mousekey depressed and drag the connection
from the input to E2 away. The connection is removed when the left mousekey is released in a free
area of the screen.
6.13.4 Executing Tool Shortcuts
A shortcut will be executed on a double-click on the entry in the Resources tree or by the command
'Open Object' in the 'Project' 'Object' menu resp. in the context menu (right mouse button).
If the execution of the file, which is defined in the shortcut properties (Parameter), fails, then an
appropriate error message will appear. If a parameter file will not be found, the exe-file of the tool will
be executed and a dialog will open, asking you whether the file should be created.
If the exe-file of the tool is not found in the defined path or if no path has been defined, then the
standard dialog for selecting a file will be opened and the user will be asked to enter the path of the
exe-file. This path will be saved when the dialog is closed by OK and thus will be available for the tool
also in other CoDeSys projects.
6.13.5 Saving Tool Shortcuts
When the CoDeSys project is saved, the status and settings of the 'Tools' folder in the Resources tree
will also be saved.
Please note: If you save a project by 'Save as' with a new name, then you must consider the following if you use
the template $(PROJECT_NAME) in the definition of the parameter file and of the files which are to
be
downloaded:
If you had added shortcuts for a tool (FixedCount=0) in the old project, then in the new project the file
names have to be renamend manually corresponding to the new project name. In contrast for a tool
which is defined with a fix number of shortcuts, the template always will be replaced automatically by
the current project name !
6.13.6 Frequently asked questions on Tools
Why do I get no entry 'Tools' in the 'Resources'
Only if it is defined in the target file of the currently set target system, the 'Tools' functionality will be
available.
For which tools already shortcuts are available, which shortcuts can I add in the CoDeSys
project
Open the folder 'Tools' in the 'Resources' tree of the Object Organizer by a double-click on the plus
sign. You will see which tools already are connected for the current project. If you have just set up a
new project and not yet worked on the Tools list, then just those entries will be displayed, which are
predefined unalterably by the definitions in the target file. Otherwise you might see an already project
specifically modifed tools list. In order to check, whether the list is extendable by new entries, select
the command 'Add Object'. You will get a dialog offering all tools for which additional shortcuts can be
created.
Which global properties do the available tools have
