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 a setting is changed, the output signal SETCHGD is sending a pulse.
Activating or deactivating test mode is made by changing a parameter,
consequently this will also cause a pulse on the SETCHGD output.
The parameter
MaxNoSetGrp
defines the maximum number of setting groups in
use to switch between.
The output
REMSETEN
indicates whether setting changes over IEC 61850 are
enabled or not. Per default, this is not enabled, which results in
REMSETEN
being
at a logical low level. If setting changes via IEC 61850 are enabled, then
REMSETEN
will be a logical high. The setting changes over IEC 61850 is enabled
with the setting
EnableSettings
in the IEC 61850-8-1 configuration under
Main
menu/Configuration/Communication/Station communication/IEC
61850-8-1/IEC 61850-8-1
. Please refer to documentation for IEC 61850 for further
details.
Switching can only be done within that number of groups. The number of setting
groups selected to be used will be filtered so only the setting groups used will be
shown on the Parameter Setting Tool.
