Setting the Home Directory for the Runtime System
The home directory for the runtime system is located in the controller's internal
memory by default. An existing boot project may be saved in the home directory.
You can use the WBM to move the home directory for the runtime system to the
memory card, e.g., to make more memory available for a large boot project or
other files.
This setting can be activated using the check box “Home directory on memory
card enabled” on the WBM page “PLC Runtime”. Click the
[Submit]
button to
apply the setting, which takes effect after the next restart.
No files are applied from the old to the new home directory.
After moving the directory, a project must be loaded and a boot project created.
It should be noted that the memory card may not be removed under any
circumstances as long as the home directory is there. If an application is running,
system safety can be endangered by an uncontrolled controller crash.
Switching the home directory has no effect if the controller was botted from a
memory card. The configuration state is saved, but only takes effect if the content
of the memory card is copied to the internal memory.
