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
