15.2.1.1 Bay control QCBAY
M16595-3 v9
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 Of
f, 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.
QCBAY also provides blocking functions that can be distributed to different
apparatuses within the bay. There are two different blocking alternatives:
• Blocking of update of positions
• Blocking of commands
