7. Control

Switch controller SCSWI
The Switch controller (SCSWI) initializes and supervises
all functions to properly select and operate switching
primary apparatuses. The Switch controller may handle
and operate on one three-phase device or up to three
one-phase devices.
Circuit breaker SXCBR
The purpose of Circuit breaker (SXCBR) is to provide the
actual status of positions and to perform the control
operations, that is, pass all the commands to primary
apparatuses in the form of circuit breakers via binary
output boards and to supervise the switching operation
and position.
Circuit switch SXSWI
The purpose of Circuit switch (SXSWI) function is to
provide the actual status of positions and to perform
the control operations, that is, pass all the commands to
primary apparatuses in the form of disconnectors or
earthing switches via binary output boards and to
supervise the switching operation and position.
Reservation function QCRSV
The purpose of the reservation function is primarily to
transfer interlocking information between IEDs in a safe
way and to prevent double operation in a bay,
switchyard part, or complete substation.
Reservation input RESIN
The Reservation input (RESIN) function receives the
reservation information from other bays. The number of
instances is the same as the number of involved bays
(up to 60 instances are available).
Bay control QCBAY
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
The signals from the local HMI or from an external local/
remote switch are connected via the function blocks
LOCREM and LOCREMCTRL to the Bay control QCBAY
function block. The parameter
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.

ControlMode in function
The logic rotating switch for function selection and
LHMI presentation SLGAPC (or the selector switch
function block) is used to get an enhanced selector
switch functionality compared 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 selector switch
function eliminates all these problems.
Selector mini switch VSGAPC
The Selector mini switch VSGAPC function block is a
multipurpose function used for a variety of applications,
as a general purpose switch.
VSGAPC can be controlled from the menu, from a symbol
on the single line diagram (SLD) on the local HMI or from
Binary inputs
Generic communication function for Double Point
indication DPGAPC
Generic communication function for Double Point
indication (DPGAPC) function block is used to send
double point position indications to other systems,
equipment or functions in the substation through IEC
61850-8-1 or other communication protocols. It is
especially intended to be used in the interlocking
station-wide logics.
Single point generic control 8 signals SPC8GAPC
The Single point generic control 8 signals SPC8GAPC
function block is a collection of 8 single point
commands that can be used for direct commands for
example reset of LED's or putting IED in "ChangeLock"
state from remote. 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 SPGAPC function blocks. The commands can
be pulsed or steady with a settable pulse time.
AutomationBits, command function for DNP3.0
AUTOBITS
AutomationBits function for DNP3 (AUTOBITS) is used
within PCM600 to get into the configuration of the
commands coming through the DNP3 protocol. The
AUTOBITS function plays the same role as functions
GOOSEBINRCV (for IEC 61850) and MULTICMDRCV (for
LON).
Single command, 16 signals
The IEDs can receive commands either from a
substation automation system or from the local HMI.
The command function block has outputs that can be
