CNTRL 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. CNTRL 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 CNTRL can be accessed locally or remotely through
communication or the LHMI control. CNTRL 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.
From the remote communication point of view, SPCGGIO toggled
operation mode is always working as persistent mode. The output O#
follows the value written to the input IN#.
