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 multi-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 (QCRSV) 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.
Proxy for signals from switching device via GOOSE
XLNPROXY
The proxy for signals from switching device via GOOSE
(XLNPROXY) gives an internal representation of the
position status and control response for a switch
modelled in a breaker IED. This representation is
identical to that of an SXCBR or SXSWI function.

GOOSEXLNRCV
The GOOSE XLN Receive component is used to collect
information from another device's XCBR/XSWI logical

node sent over process bus via GOOSE. The GOOSE XLN
Receive component includes 12 different outputs (and
their respective channel valid bits) with defined names
to ease the 61850 mapping of the GOOSE signals in the
configuration process.
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
local remote (LOCREM) and local remote control
(LOCREMCTRL) to the Bay control (QCBAY) function
ControlMode in function block
block. The parameter
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.
Voltage control TR1ATCC/TR8ATCC , TCMYLTC/
TCLYLTC
Automatic voltage control for tap changer, single
control (TR1ATCC), Automatic voltage control for tap
changer, parallel control (TR8ATCC), Tap changer control
and supervision, 6 binary inputs (TCMYLTC) and Tap
changer control and supervision, 32 binary inputs
(TCLYLTC) are used for control of power transformers
with an on-load tap changer. The functions provide
automatic regulation of the voltage on the secondary
side of transformers or alternatively on a load point
further out in the network.
Control of a single transformer, as well as control of up
to eight transformers in parallel is possible. For parallel
control of power transformers, three alternative
methods are available: the master-follower method, the
circulating current method and the reverse reactance
method. The first two methods require exchange of
information between the parallel transformers and this
is provided for within IEC 61850-8-1.
Voltage control includes many extra features such as the
possibility to avoid simultaneous tapping of parallel
transformers, hot stand by regulation of a transformer
in a group which regulates it to a correct tap position
even though the LV CB is open, compensation for a
possible capacitor bank on the LV side bay of a
transformer, extensive tap changer monitoring including
contact wear and hunting detection, monitoring of the
power flow in the transformer so that, for example, the
voltage control can be blocked if the power reverses,
etc.
Logic rotating switch for function selection and
LHMI presentation SLGAPC
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
