need to be blocked from the protection, the application configuration must be
used to block these signals. The blocking scheme needs to use BEH_BLK output of
PROTECTION function block.
BEH_BLK signal can be used to
• Connect to TRPPTRC BLOCK input. This is the best option when all protection
signaling goes through the master trip function.
• Connect to necessary protection function BLOCK inputs.
• Create logic condition for physical outputs to block state changes when BEH_BLK
is active.
11.8.3 Control mode
The mode of all logical nodes located under CTRL logical device can be set with
Control mode
. The
Control mode
parameter is available via the HMI or PCM600
path Configuration> Control> General. By default,
Control mode
can only be set
locally through LHMI.
Control mode
inherits its value from
Test mode
but
Control
mode
”On”, “Blocked” and “Off” can also be set independently.
Control mode
is also
available via IEC 61850 communication (CTRL.LLN0.Mod).
Table 1657: Control mode
Control mode Description Control BEH_BLK
On Normal operation FALSE
Blocked Control function commands blocked TRUE
Off Control functions disabled FALSE
See function block Control for more details.
The behavior data objects under CTRL logical device follow
CTRL.LLN0.Mod value. If "On" is selected, behavior data objects follow
the mode of the corresponding logical device.
11.8.4 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.
11.8.5 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 by setting parameter
Test mode selection
via Configuration>
System. Remote operation is possible only when the relay's control position is in
remote position. Local and remote control can be selected with R/L button or via
Control function block in application configuration.
