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 BLOCK
input is active. If Operation mode is "Pulsed", the activation of the BLOCK input resets
the outputs to the "False" state and further control requests are ignored while the
BLOCK input is active.
From the remote communication point of view SPCGAPC toggled
operation mode is always working as persistent mode. The output O#
follows the value written to the input IN#.
