Logic rotating switch for function
selection and LHMI presentation
SLGGIO
The logic rotating switch for function
selection and LHMI presentation function
(SLGGIO) (or the selector switch function
block) is used to get a selector switch
functionality similar to the one provided by a
hardware selector switch. Hardware selector
switches are used extensively by utilities, in
order to have different functions operating on
pre-set values. Hardware switches are
however sources for maintenance issues,
lower system reliability and an extended
purchase portfolio. The logic selector
switches eliminate all these problems.
Selector mini switch VSGGIO
The Selector mini switch VSGGIO function
block is a multipurpose function used for a
variety of applications, as a general purpose
switch.
VSGGIO can be controlled from the menu or
from a symbol on the single line diagram
(SLD) on the local HMI.
IEC 61850 generic communication
I/O functions DPGGIO
The IEC 61850 generic communication I/O
functions (DPGGIO) function block is used to
send double indications to other systems or
equipment in the substation. It is especially
used in the interlocking and reservation
station-wide logics.
Single point generic control 8
signals SPC8GGIO
The Single point generic control 8 signals
(SPC8GGIO) function block is a collection of
8 single point commands, designed to bring
in commands from REMOTE (SCADA) to
those parts of the logic configuration that do
not need extensive command receiving
functionality (for example, SCSWI). In this
way, simple commands can be sent directly
to the IED outputs, without confirmation.
Confirmation (status) of the result of the
commands is supposed to be achieved by

other means, such as binary inputs and
SPGGIO function blocks. The commands can
be pulsed or steady.
AutomationBits AUTOBITS
The Automation bits function (AUTOBITS) is
used to configure the DNP3 protocol
command handling.

Tripping logic SMPPTRC
A function block for protection tripping is
provided for each circuit breaker involved in
the tripping of the fault. It provides the pulse
prolongation to ensure a trip pulse of
sufficient length, as well as all functionality
necessary for correct co-operation with
autoreclosing functions.
The trip function block includes functionality
for breaker lock-out.
Trip matrix logic TMAGGIO
Trip matrix logic TMAGGIO function is used
to route trip signals and other logical output
signals to different output contacts on the IED.
TMAGGIO output signals and the physical
outputs allows the user to adapt the signals
to the physical tripping outputs according to
the specific application needs.
Configurable logic blocks
A number of logic blocks and timers are
available for the user to adapt the
configuration to the specific application needs.
• OR function block.
• INVERTER function blocks that inverts the
input signal.
• PULSETIMER function block can be used,
for example, for pulse extensions or
limiting of operation of outputs.
