At delivery, logging on is not required and the user has full access until users and passwords
are created with PCM600 and written into the IED or Centralized Account Management is
enabled.
Commands, changing parameter values and resetting indications, for example, are actions
requiring password when the password protection is activated. Reading information on the
LHMI is always allowed without password.
Utility security policies and practical consideration should always be taken on
the feasibility of using passwords. In emergency situations, the use of
passwords could delay urgent actions. On the other hand when security issues
must be met, the two factors must be seriously considered.
Do not switch off the auxiliary power supply to the IED before changes, for
example, setting parameter or local/remote control state changes are saved.
