3.7.5 Application configuration and Control mode
The physical outputs from commands to process are blocked with “Blocked“ mode.
If physical outputs need to be blocked totally, meaning also commands from the
binary inputs, the application configuration must be used to block these signals.
Blocking scheme uses BEH_BLK output of CONTROL function block.
3.7.6 Authorization
By default,
Test mode
and
Control mode
can only be changed from LHMI. It is
possible to write test mode by remote client, if it is needed in configuration. This
is done via LHMI only by setting the
Remote test mode
parameter via Tests >
IED test > Test mode. Remote operation is possible only when control position of
the relay is in remote position. Local and remote control can be selected with R/L
button or via Control function block in application configuration.
When using the Signal Monitoring tool to force online values, the following
conditions need to be met.
•
Remote force
is set to “All levels”
•
Test mode
is enabled
• Control position of the relay is in remote position
