Bay control (QCBAY)
The Bay control (QCBAY) is used to handle the selection of the operator place for the bay.
The function gives permission to operate from two 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 neither from local nor
from remote.
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
The function does not have a corresponding functionality defined in the IEC 61850
standard, which means that this function is included as a vendor specific logical node.
can also be realized over the station bus according to the
