Figure 4.1-17 depicts the cancel logic when a “Cancel command (Local-cancel)” signal is applied
to the SPOS01 function. The signal is generated when the “Cancel” key is pressed on the IED
front panel; the user is not required to take account of mapping. When the logic receives the
“Local-cancel” signal, the logic is able to output a result signal; provided that the “cancel
condition” checking is satisfied.
