Using the local HMI

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.

Using the HMI

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.
