8. Control

Bay control QCBAY

M13447-3 v5

The Bay control QCBAY function is used together with
Local remote and local remote control functions to handle
the selection of the operator place per bay. QCBAY also
provides blocking functions that can be distributed to
different apparatuses within the bay.

Local remote LOCREM /Local remote control

LOCREMCTRL

M17086-3 v4

The signals from the local HMI or from an external local/
remote switch are applied via the 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

SEMOD114908-4 v6

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

SEMOD158756-5 v5

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

SEMOD55850-5 v3

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

SEMOD176462-4 v5

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

SEMOD158591-5 v4

The Automation bits function (AUTOBITS) is used to
configure the DNP3 protocol command handling.

9. Logic

Tripping logic SMPPTRC (94)

M12275-3 v5

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.

Trip matrix logic TMAGGIO

M15321-3 v7

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

M11396-4 v10

A number of logic blocks and timers are available for the
user to adapt the configuration to the specific application
needs.

•

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.
