If you choose this category in the Options dialog box, then you get the following dialog box:
Directories can be entered in the Project and Common areas for CODESYS to use in searching for Libraries, controller Configuration and Visualization files (bitmaps, XML file for dynamic texts etc.) iles, as well as for storing Compile and source-Upload files. (Compile files for example are map- and list-files, not however e.g. symbol files ! The latter will be saved in the project directory.) If you activate the button (...) behind a field, the directory selection dialog opens. For library and configuration files, several paths can be entered for each, separated by semicolons ";".
Please regard: Library paths can be entered based on the project file's path by prefixing a dot ".". If e.g. ".\libs" is entered, the libraries will be searched in 'C:\programs\projects\libs', if the current project is in 'C:\programs\projects'. For information on library paths see also: 'Insert' 'Additional Library'.
Please regard: Do not use empty spaces and special characters except for "_" in the directory pathes.
The Target area just displays the directories for libraries and configuration files set in the target system, e.g. through entries in the Target file. These fields cannot be edited, but an entry can be selected and copied (right mouse button context menu).
CODESYS generally searches first in the directories entered in 'Project', then in those in 'Target' (defined in the Target file), and finally those listed under 'Common'. If two files with identical names are found, the one in the directory that is browsed first will be used.
The settings for area Common will be stored in CODESYS, those for area Project in the project..
