• Bay control QCBAY
• Local remote LOCREM
• Local remote control LOCREMCTRL
SCSWI, SXCBR, QCBAY and SXSWI are logical nodes according to IEC 61850.
The signal flow between these function blocks appears in figure
95. The function
Logical node Interlocking (SCILO) in the figure 95 is the logical node for
interlocking.
Control operation can be performed from the local IED HMI. If the administrator has
defined users with the UMT tool, then the local/remote switch is under authority
control. If not, the default (factory) user is the SuperUser that can perform control
operations from the local IED HMI without LogOn. The default position of the local/
remote switch is on remote.

The IEC 61850 communication has always priority over binary
inputs, e.g. a block command on binary inputs will not prevent
commands over IEC 61850.
