Operation principle

The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
SPCLGAPC 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. SPCLGAPC 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 SPCLGAPC can only be accessed through the LHMI control.
SPCLGAPC follows the local or remote (L/R) state if the Loc Rem restriction setting
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.
