function blocks LOCREM and LOCREMCTRL to
the Bay control (QCBAY) function block. A
parameter in function block LOCREM is set to
choose if the switch signals are coming from
the local HMI or from an external hardware
switch connected via binary inputs.
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.
9. Logic
Tripping logic SMPPTRC (94)
A function block for protection tripping is
provided for each circuit breaker involved in
the tripping of the fault. It provides 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.
Tripping logic SPTPTRC (94)
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 cooperation with autoreclosing and
communication logic functions.
The trip function block includes functionality
for evolving faults and breaker lock-out.
