The functions Local Remote (LOCREM) and Local Remote Control (LOCREMCTRL), to handle the
local/remote switch, and the functions Bay reserve (QCRSV) and Reservation input (RESIN), for the
reservation function, 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.
14.3.3 Error handling
Depending on the error that occurs during the command sequence the error signal will be set with
a value. Table
values specified in IEC 61850-8-1 is shown in Table 477. 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), Circuit breaker (SXCBR) and
Circuit switch (SXSWI) 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 478.

Name Description
None Control action successfully executed
Not-supported Given for Cancel request with Direct Control in Ready state
Blocked-by-switching- Not successful since one of the downstream Loc switches like
hierarchy in CSWI has the value TRUE
Select-failed Cancelled due to an unsuccessful selection (select service)
Invalid-position Control action is aborted due to invalid switch position (Pos in
XCBR or XSWI)
Position-reached Switch is already in the intended position (Pos in XCBR or
XSWI)
Parameter-change-in- Control action is blocked due to running parameter change
execution
Step-limit Control action is blocked, because tap changer has reached
the limit (EndPosR or EndPosL in YLTC)
Blocked-by-Mode Control action is blocked, because the LN (CSWI or XCBR/
XSWI) is in a mode (Mod) which doesn't allow any switching
Blocked-by-process Control action is blocked due to some external event at
process level that prevents a successful operation, for
example blocking indication (EEHealth in XCBR or XSWI)
Blocked-by- Control action is blocked due to interlocking of switching
interlocking devices (in CILO attribute EnaOpn.stVal="FALSE" or
EnaCls.stVal="FALSE"
Blocked-by- Control action with synchrocheck is aborted due to exceed of
synchrocheck time limit and missing synchronism condition
Command-already-in- Control, select or cancel service is rejected, because control
execution action is already running
Blocked-by-health Control action is blocked due to some internal event that
prevents a successful operation (Health)
