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 SETCHGD is sending a
pulse.
The parameter MaxNoSetGrp defines the maximum number of setting groups in
use to switch between.
