3.17.13.2 Functionality
The remote generic control points function SPCRGAPC is dedicated only for remote
controlling, that is, SPCRGAPC cannot be controlled locally. The remote control is
provided through communications.
3.17.13.3 Operation principle
The function can be enabled and disabled with the
Operation
setting. The
corresponding parameter values are "On" and "Off".
SPCRGAPC has the
Operation mode
,
Pulse length
and
Description
settings available
to control all 16 outputs. By default, the
Operation mode
setting is set to "Off". This
disables the controllable signal output. SPCRGAPC also has a general setting
Loc
Rem restriction
, which enables or disables the local or remote state functionality.
When the
Operation mode
is set to "Toggle", the corresponding output toggles
between "True" and "False" for every input pulse received. The state of the output is
stored in a nonvolatile memory and restored if the protection relay is restarted.
When the
Operation mode
is set to "Pulsed", the corresponding output can be used
to produce the predefined length of pulses. Once activated, the output remains
active for the duration of the set pulse length. When activated, the additional
activation command does not extend the length of pulse. Thus, the pulse needs
to be ended before the new activation can occur.
The
Description
setting can be used for storing signal names for each output.
Each control point or SPCRGAPC can only be accessed remotely through
communication. SPCRGAPC follows the local or remote (L/R) state if the setting
Loc Rem restriction
is "true". If the
Loc Rem restriction
setting is "false", local or
remote (L/R) state is ignored, that is, all controls are allowed regardless of the local
or remote state.
The BLOCK input can be used for blocking the output functionality. The BLOCK input
operation depends on the
Operation mode
setting. If the
Operation mode
setting is
set to "Toggle", the output state cannot be changed when the input BLOCK is TRUE.
If the
Operation mode
setting is set to "Pulsed", the activation of the BLOCK input
resets the output to the FALSE state.
