16.4.3.4 Settings
The function does not have any settings available in Local HMI or Protection and Control IED
Manager (PCM600).
16.4.4 Operation principle
Parameter setting groups (ACTVGRP) function has four functional inputs, each corresponding to
one of the setting groups stored in the IED. Activation of any of these inputs changes the active
setting group. Five functional output signals are available for configuration purposes, so that up
to date information on the active setting group is always available.
A setting group is selected by using the local HMI, from a front connected personal computer,
remotely from the station control or station monitoring system or by activating the corresponding
input to the ACTVGRP function block.
Each input of the function block can be configured to connect to any of the binary inputs in the
IED. To do this PCM600 must be used.
The external control signals are used for activating a suitable setting group when adaptive
functionality is necessary. Input signals that should activate setting groups must be either
permanent or a pulse exceeding 400 ms.
More than one input may be activated at the same time. In such cases the lower order setting
group has priority. This means that if for example both group four and group two are set to
activate, group two will be the one activated.
Every time the active group is changed, the output signal GRP_CHGD is sending a pulse.
