PLC Programming

Managing Projects...
'File' 'Open'
Symbol:
With this command you open an already existing project. If a project has already been opened and
changed, then CoDeSys asks whether this project should be saved or not.
The dialog box for opening a file appears, and a project file with the extension "*.pro" or a library file
with the extension "*.lib" must be chosen. This file must already exist. It is not possible to create a
project with the command "Open".
Dialog box for opening a file
To upload a project file from the PLC, press PLC at Open project from PLC. You will obtain, as next,
the dialog Communication parameters (see menu 'Online' 'Communication parameters') for setting the
transmission parameters when no connection exists yet to the PLC. Once an on-line connection has
been created, the system checks whether the same named project files already exist in the directory
on your computer hard disc. When this is the case you receive the dialogue Load the project from
the controller where you can decide whether the local files should be replaced by those being used
by the controller. (This sequence is the reverse of the sequence of 'Online' 'Load source code', with
which the project source file is stored in the controller. Do not confuse with 'Create Boot project'!)
Note:
Please note, that you in any case have to give a new name to a project, when you load it from the
PLC to your local directory, otherwise it is unnamed.
If there has not yet been loaded a project to the PLC, you get an error message.
(See also 'Project' 'Options' category 'Sourcedownload').
To open a project which is stored in a ENI project data base, activate option Open project from
Source code manager can be used . It is a precondition that you have access to an ENI Server
which serves the data base. Press button ENI... , to get a dialog where you can connect to the server
concerning the data base category 'Project objects'.
Insert the appopriate access data (TCP/IP-Address, Port, User name, Password, Read only) and the
data base folder (Project name) from which the objects should be get and confirm with Next. The
dialog will be closed and another one will open where you have to insert the access data for the data
base category 'Shared objects'. If you press button Finish the dialog will be closed and the objects of
the defined folders will automatically be retrieved and displayed in the CoDeSys Object manager. If
you want to continue to keep the project objects under data base control, then open the Project
options dialogs to set the desired parameters.
