Error handling
Depending on the error that occurs during the command sequence, the error signal will
be set with a value. Table
these specified in IEC 61850-8-1 standard. The list of values of the "cause" are in
order of priority. The values are available over the IEC 61850. An output L_CAUSE
on the function block indicates the latest value of the error during the command.

Circuit breaker SXCBR

The users of the Circuit breaker function (SXCBR) is other functions such as for
example, switch controller, protection functions, autorecloser function or an IEC
61850 client residing in another IED or the operator place. This switch function
executes commands, evaluates block conditions and evaluates different time
supervision conditions. Only if all conditions indicate a switch operation to be
allowed, the function performs the execution command. In case of erroneous
conditions, the function indicates an appropriate "cause" value.
SXCBR has an operation counter for closing and opening commands. The counter
value can be read remotely from the operator place. The value is reset from a binary
input or remotely from the operator place by configuring a signal from the Single Point
Generic Control 8 signals (SPC8GGIO) for example.
Local/Remote switch
One binary input signal LR_SWI is included in SXCBR to indicate the local/remote
switch position from switchyard provided via the I/O board. If this signal is set to
TRUE it means that change of position is allowed only from switchyard level. If the
signal is set to FALSE it means that command from IED or higher level is permitted.
When the signal is set to TRUE all commands (for change of position) from internal
IED clients are rejected, even trip commands from protection functions are rejected.
The functionality of the local/remote switch is described in figure 120.
