3.7.4 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 39: Control mode
Control mode Description Control BEH_BLK
On Normal operation FALSE
Blocked Control function commands blocked TRUE
Off Control functions disabled FALSE
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.
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
