control function reflecting the switchyard configuration. The total number used
depends on the switchyard configuration. These types are:
• Bay control QCBAY
• Switch controller SCSWI
• Circuit breaker SXCBR
Another function block type for supervision and control is the XLNPROXY. It is
used for interfacing a switch with its primary representation in a breaker IED.
XLNPROXY facilitates a common interface with the SXCBR function towards the
SCSWI function, especially for command response and error handling.
The functions Local Remote (LOCREM) and Local Remote Control
(LOCREMCTRL), to handle the local/remote switch, also belong to the apparatus
control function.
The principles of operation, function blocks, input and output signals and setting
parameters for all these functions are described below.

Error handling

Depending on the error that occurs during the command sequence the error signal
will be set with a value. Table
The translation to AddCause values specified in IEC 61850-8-1 is shown in Table
184. For IEC 61850-8-1 edition 2 only addcauses defined in the standard are used,
for edition 1 also a number of vendor specific causes are used. The values are
available in the command response to commands from IE C61850-8-1 clients. An
output L_CAUSE on the function block for Switch controller (SCSWI) and Circuit
breaker (SXCBR) indicates the value of the cause during the latest command if the
function specific command evaluation has been started. The causes that are not
always reflected on the output L_CAUSE, with description of the typical reason
are listed in table 185.

Description
Control action successfully executed
Given for Cancel request with Direct Control in Ready
state
Not successful since one of the downstream Loc
switches like in CSWI has the value TRUE
Cancelled due to an unsuccessful selection (select
service)
Control action is aborted due to invalid switch position
(Pos in XCBR)
Switch is already in the intended position (Pos in
XCBR)
Control action is blocked due to running parameter
change
