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.
