The binary input controlling the function is defined in ACT or SMT. The CHNGLCK function is
configured using ACT.
LOCK
ACTIVE
OVERRIDE
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.
15.5.3 Setting guidelines
The Change lock function CHNGLCK does not have any parameters available in the local HMI or
PCM600.

15.6.2 Application
15.6.2.1 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.
