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.
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.
HMI operations are possible only for authorized users.
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.
A mechanism for limiting the number of writings per time period is included in the
IED to prevent the flash memory from wearing out due to too many writings caused
by the application configuration. As a consequence, saving application function states
may take up to an hour. If the auxiliary power is interrupted before the states are saved,
that change is lost. Settings and configuration parameters are saved without delay.
