3.20.13.3 Functionality
The generic control points function SPCGAPC contains 16 independent control
points. SPCGAPC offers the capability to activate its outputs through a local or
remote control. The local control request can be issued through the buttons in
the single-line diagram or via inputs and the remote control request through
communication. The rising edge of the input signal is interpreted as a control
request, and the output operation is triggered. When remote control requests are
used the control points behaves as persistent.
The
Loc Rem restriction setting is used for enabling or disabling the restriction for
SPCGAPC to follow the R/L button state. If
Loc Rem restriction is "True", as it is by
default, the local or remote control operations are accepted according to the R/L
button state.
Each of the 16 generic control point outputs has the
Operation mode, Pulse length
and
Description setting. If Operation mode is "Toggle", the output state is toggled
for every control request received. If Operation mode is "Pulsed", the output pulse
of a preset duration (the
Pulse length setting) is generated for every control request
received. The
Description setting can be used for storing information on the actual
use of the control point in application, for instance.
For example, if the
Operation mode is "Toggle", the output O# is initially “False”.
The rising edge in IN# sets O# to “True”. The falling edge of IN# has no effect. Next
rising edge of IN# sets O# to “False”.

The
BLOCK
input can be used for blocking the functionality of the outputs. The
operation of the
BLOCK
input depends on the Operation mode setting. If Operation
mode is "Toggle", the output state freezes and cannot be changed while the
