4.5.2 Disabling Logical Ports
It is possible to disable unused logical ports. A level 3 password is needed to perform this
action.
Note : The port disabling setting cells are not provided in the settings file
CAUTION: DISABLING THE ETHERNET PORT WILL DISABLE ALL ETHERNET
BASED COMMUNICATIONS.
If it is not desirable to disable the Ethernet port, it is possible to disable selected protocols on
the Ethernet card and leave others functioning.
Three protocols can be disabled:
−
IEC61850
−
DNP3 Over Ethernet
−
Courier Tunnelling
Note : If any of these protocols are enabled or disabled, the Ethernet card
will reboot.
4.6 Logging out
If you have been configuring the IED, you should 'log out'. You do this by going up to the top
of the menu tree. When you are at the Column Heading level and you press the Up button,
you may be prompted to log out with the following display:
DO YOU WANT TO
LOG OUT?
You will only be asked this question if your password level is higher than the fallback level.
If you confirm, the following message is displayed for 2 seconds:
LOGGED OUT
Access Level <x>
Where x is the current fallback level.
If you decide not to log out (i.e. you cancel), the following message is displayed for 2
seconds.
LOGOUT CANCELLED
Access Level <x>
Where x is the current access level.
