Cancel logic for SBO mode
4.3.3
In the SBO control mode, the reception of a cancel command is possible; when the cancel
conditions are satisfied, accordingly, the function can discard the select command.
Receiving "Cancel" from remote-end
(i)
Figure 4.3-13 shows the logic when a "Cancel command (Remote-Cancel)" signal is applied to
the SOFTSW1 function. The input-point "S4301_CONTROL_REQ" is the same as the
"Selection command (Remote-On-Control)" signal.

Command "Remote-cancel"

†Note: The criteria "unmatched conditions" are determined when the "Test-bit status" in
the 'cancel' command is not identical to the "IED test status".
Receiving "Cancel" from local-end
(ii)
Figure 4.3-14 shows the logic when a "Cancel command (Local-cancel)" signal is applied to the
SOFTSW1 function. The input signal is provided when the "Cancel" key is pressed on the IED
front panel; the user is not required to map it. When the logic receives input "Local-cancel"
signal, the logic is able to output a result signal, provided that the "unmatched condition
detected" checking is satisfied.

Command "Local-cancel"

the 'cancel' command is not identical to the "IED test status".
Operate logic for SBO/DIR modes
4.3.4
The user should map the operation command to the operate logic. If the operation conditions
are satisfied, the IED is able to change the state in the SOFWSW1–61 (S43-01 to S43-61).
