the relay over FTP/FTPS. Authentication on the LHMI is required to use USB
communication with PCM600.
If the PCM600 authentication has been enabled in PCM600 System
Settings, a relay user can be linked to the current PCM600 user by
selecting the Remember me check box in the Login dialog. After
that, the user credentials are no longer asked at tool communication
as logging in PCM600 also provides the authentication credentials
to the protection relay.
The Administrator user shall not be allowed to delete the last
ADMINISTRATOR user and itself. FTP/FTPS logins are done by
entering the username and password; there is no role selection
required. The highest role for the username is automatically
selected by the protection relay. Performing the Restore Factory
settings operation in IED Users in PCM600 restores user accounts
to the factory user accounts.
