Figure 22: Download password file
To upload a before downloaded password file on another RTU the file can be dropped to the dotted
area shown in the figures above or the area can be clicked with the mouse. In the second case a
file select dialog appears to choose the password file to upload. In both cases a confirmation dialog
appears to confirm the upload. After confirmation with "Ok" the existing password file is replaced
by the uploaded file. If successful, the new password file is active directly. A reset of the RTU500
series is not necessary, but all users are logged out and a re-login is required.
2.5.6
Password file harmonization
In normal operation mode all changes described in chapter "User Management" are automatically
distributed to all communication units and stored in the password file of each unit (no restart of the
RTU required).
In case of:
– Adding a new communication unit into the system
– Missing/faulty communication unit during the changes
the password file between different CMU's can became inconsistent.
In case the password file is inconsistent between different CMU's the RTU500 series goes into a
restricted mode. In this mode a login is possible but the only function available is the harmonization
of the password file. The harmonization of the password file requires administrator permissions.
In restricted mode the Web server shows after login without administrator permissions the error
message displayed below.
