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
GUID-6C31D291-74E8-46A3-8FC2-D3959C2458A5 v7
Depending on the error that occurs during the command sequence the error signal will be set with
a value. Table
476 describes the cause values given on local HMI. The translation to AddCause
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.
Table 476: Values for "cause" signal
Cause
number
Name Description Supported
0 None Control action successfully executed X
1 Not-supported Given for Cancel request with Direct Control in Ready state X
2 Blocked-by-switching-
hierarchy
Not successful since one of the downstream Loc switches like
in CSWI has the value TRUE
X
3 Select-failed Cancelled due to an unsuccessful selection (select service) X
4 Invalid-position Control action is aborted due to invalid switch position (Pos in
XCBR or XSWI)
X
5 Position-reached Switch is already in the intended position (Pos in XCBR or
XSWI)
X
6 Parameter-change-in-
execution
Control action is blocked due to running parameter change X
7 Step-limit Control action is blocked, because tap changer has reached
the limit (EndPosR or EndPosL in YLTC)
X
8 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
X
9 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)
X
10 Blocked-by-
interlocking
Control action is blocked due to interlocking of switching
devices (in CILO attribute EnaOpn.stVal=”FALSE” or
EnaCls.stVal=”FALSE”
X
11 Blocked-by-
synchrocheck
Control action with synchrocheck is aborted due to exceed of
time limit and missing synchronism condition
X
12 Command-already-in-
execution
Control, select or cancel service is rejected, because control
action is already running
X
13 Blocked-by-health Control action is blocked due to some internal event that
prevents a successful operation (Health)
X
