„ Opening from the File Manager
As shown below, open the relevant PLC folder from the tree on the left side of the File Man-
ager.
Open the Definition Folder from the PLC Folder, and then move the cursor to the desired
definition file and double-click. The files contained in the selected folder will also be dis-
played in the right window of the File Manager, so double-clicking the file here will have the
same effect.
„ Opening from the Engineering Manager
The definition menu can be displayed by selecting File (F), Open (O), and then Definition
(D) from the Engineering Manager Window. Select the desired item from the menu.
„ New Definition Files
When a system information definition file is opened for the first time, there is no existing
data and a dialog box will be displayed to confirm that a new file is to be created. Click the
OK Button to continue with the definition operations.
4.1.3 Updating Files in Online Mode and Offline Mode
When the data files are created or modified, where they are stored depends on whether the
Machine Controller has been logged onto in online mode or offline mode.
„ Logging in Online
When in online mode, the data stored at the Machine Controller is accessed. When data is
newly created or modified, it is saved to both the Machine Controller and the hard disk.
„ Logging in Offline
When in offline mode, the Machine Controller is not connected, and the data stored on the
hard disk is accessed. When data is newly created or modified, it is saved only to the hard
disk. When data is created in offline mode, the data file must later be transferred to the
Machine Controller in online mode to enable using it in the Machine Controller. If the data
file is not transferred, the data in the Machine Controller will not be changed.
