Figure 139: Signal flow between apparatus control functions with XCBR and XSWI located
in a breaker IED
Control operation can be performed from the local IED HMI. If users are defined in the IED,
then the local/remote switch is under authority control, otherwise the default user can
perform control operations from the local IED HMI without logging in. The default position of
the local/remote switch is on remote.
Accepted originator categories for PSTO
If the requested command is accepted by the authority control, the value will change.
Otherwise the attribute
blocked-by-switching-hierarchy is set in the cause signal. If the PSTO
value is changed during a command, then the command is aborted.
