Table 500: 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
15.3.3.4 Settings
The function does not have any settings available in Local HMI or Protection and
Control IED Manager (PCM600).
15.3.4 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 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 be activated, group two will be the one activated.
Every time the active group is changed, the output signal SETCHGD is sending a
pulse. This signal is normally connected to a SP16GGIO function block for external
communication.
The parameter MaxNoSetGrp defines the maximum number of setting groups in use
to switch between.
