„ Deleting Default Users
The default user can be deleted by clearing the user name and password in the Default User
Set Window and clicking the OK Button.
The default user is not saved on the Machine Controller or hard disk, and, therefore, is deleted if the
File Manager is closed or the system rebooted. The default user must be reset if the CP-717 is restarted.
2.1.6 Switching between Online
1
and Offline
2
Modes
Once a PLC folder has been registered, logging on to the CPU is possible, but always be
aware of whether login is being performed online or offline.
When online, the Engineering Tool's hard disk and the MP900 Series' data are both updated
simultaneously, but when offline, only the Engineering Tool's hard disk is updated. Conse-
quently, caution is required.
The procedure to switch between online and offline modes is given below.
1. Click the PLC folder which is to be switched to either online or offline mode.
2. Click File (F) and then Properties (R) on the File Manager Menu. Alternatively, right-
click the PLC folder and make the selections from the pop-up menu.
3. Click either Yes or No for Online on the Network tab page in the Controller Configura-
tion Window, and then click the OK Button.
1 Online Mode
The Engineering Tool and the MP900-series Machine Controller are connected using a serial communica-
tions connection and data is transferred back and forth between them via the CP-717. The CP-717 must be
online to display or update Machine Controller data. When the data is updated, both the Engineering Tool
hard disk and the MP900-series Machine Controller data are updated.
2 Offline Mode
The Engineering Tool is operated independently of the Engineering Tool. Machine Controller data cannot
be referred or updated. Only data stored on the hard disk can be accessed.
