The program can be run in a read only mode by ticking the "Read only" check box,
i.e. the data can be viewed but not changed.
When the HMI500 software establishes communication with a
REB500 system initially user must enter a password.
For details about security management, passwords and security
options refer to the "Security Deployment Guideline".
HMI500 obtains the specific device data from a database in a file, which is stored
both in the PC and the protection system. Database files on the PC have the
extension *.mdb.
Click on "OK" to continue start-up or on "Cancel" to close the program.
When you click on OK, HMI500 tests communication with the protection system
and starts in the on-line mode if communication can be established. Otherwise it
starts either in in off-line or simulation mode (see Section 3.9.5.).
Some of the dialogs used by the program are standard Windows dialogs, whose
language depends on the language setting of the operating system.
The database that was open during the last session opens
automatically. If no database was open before, select "Open" in the
"File" menu and then the desired file. An error message is displayed
if an attempt is made to open an incompatible file. An existing file
in the protection system can also be opened using the "Upload"
function in the "File" menu.
