Section 12
Control
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.
The accepted originator categories for each PSTO value are shown in
Table 42:
Permitted Source To Operate
0 = Off
1 = Local
2 = Remote
3 = Faulty
4 = Not in use
5 = All
6 = Station
7 = Remote
PSTO = All, then it is no priority between operator places. All operator places are allowed to operate.
According to IEC 61850 standard the orCat attribute in originator category are defined in
Table 43:

12.3.3 Bay control QCBAY
The Bay control (QCBAY) is used to handle the selection of the operator place per bay. The function
gives permission to operate from two main types of locations either from Remote (for example, control
centre or station HMI) or from Local (local HMI on the IED) or from all (Local and Remote). The Local/
Remote switch position can also be set to Off, which means no operator place selected that is, operation
is not possible either from local or from remote.
For IEC 61850-8-1 communication, the Bay Control function can be set to discriminate between
commands with orCat station and remote (2 and 3). The selection is then done through the IEC
61850-8-1 edition 2 command LocSta.
