The TPOS01 function can issue a "Success to cancel" signal at the monitoring, point
"TPOS01_CC_SS", when the TPOS01 function has determined that the "Remote-cancel" signal
is true. Another "Operate failed" signal is issued at monitoring point "TPOS01_CC_FS" if the
TPOS01 function is able to determine that the "Remote-cancel" signal is not true.

Input signal
Figure 4.9-24 depicts the cancel logic when a "Cancel command (Local-cancel)" signal is applied
to the TPOS01 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.
