LOCK Binary input signal that will activate/deactivate the function, defined in ACT or SMT.
ACTIVE Output status signal
OVERRIDE Set if function is overridden
When CHNGLCK has a logical one on its input, then all attempts to modify the IED
configuration and setting will be denied and the message "Error: Changes blocked" will
be displayed on the local HMI; in PCM600 the message will be "Operation denied by
active ChangeLock". The CHNGLCK function should be configured so that it is
controlled by a signal from a binary input card. This guarantees that by setting that signal
to a logical zero, CHNGLCK is deactivated. If any logic is included in the signal path to
the CHNGLCK input, that logic must be designed so that it cannot permanently issue a
logical one to the CHNGLCK input. If such a situation would occur in spite of these
precautions, then please contact the local ABB representative for remedial action.

Setting guidelines

The Change lock function CHNGLCK does not have any parameters available in the local
HMI or PCM600.

Application
Customer specific settings
The customer specific settings are used to give the IED a unique name and address. The
settings are used by a central control system to communicate with the IED. The customer
specific identifiers are found in the local HMI under Configuration/Power system/
Identifiers/TERMINALID
The settings can also be made from PCM600. For more information about the available
identifiers, see the technical manual.
