Table 23: ACTVGRP Output signals
Name Type Description
GRP1 BOOLEAN Setting group 1 is active
GRP2 BOOLEAN Setting group 2 is active
GRP3 BOOLEAN Setting group 3 is active
GRP4 BOOLEAN Setting group 4 is active
SETCHGD BOOLEAN Pulse when setting changed
3.7.3.3 Settings
The function does not have any parameters available in LHMI or PCM600.
3.7.4 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.
A setting group is selected by using the LHMI, 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 with PCM600 to connect to any of
the binary inputs in the IED.
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 is 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.
