4.2.2 Cancel logic for SBO mode
In the SBO control mode, the reception of a cancel command is possible; when the cancel
conditions are satisfied, accordingly, the IED can discard the select command; finally, the
operation returns to the initial stage (i.e., “Wait for a command”.)
(i) Receiving “Cancel” from the remote-end
Figure 4.2-14 depicts the cancel command procedure for a cancel command initiated from the
remote-end.
