The DPSY01 function, illustrated in Figure 4.1-17, is able to issue a "Select to cancel" signal
at the monitoring point "DPSY01_CC_SS", when the DPSY01 function determines that the
"Local-Cancel" signal is true.
Cancel condition logic
(iii)
Figure 4.1-18 shows the cancel condition logic. As the criteria "Unmatched condition detected"
is connected normally for the cancel logic, set Fixlogic for the scheme switch [DPSY01-
LGCNFFCT].

DPSY01IN_TMP_46
Note: The criteria "unmatched conditions" are determined when the "Test-bit status" in
1
the 'cancel' command is not identical to the "IED test status".
Note: With the exception of the above 'cancel' logic, there is an operate-condition logic
2
within the DPSY01 function; the operate-condition logic will always checks
conditions. That is, the user is only required to set either the "operate-condition"
or the "cancel-condition" logic.
If the original logic does not meet with the requirements of the user, it can be replaced
using the connection point "User configurable condition":
1.
Connect the user-customized logic with the "DPSY01IN_TMP_46", which is listed in Table 4.1-11.
2.
Set scheme switch [DPSY01-LGCNFFCT] to PLC.

"O" indicates that the signal is provided for optional usage.
"M" indicates that the user should map/set/configure using the signal;
otherwise, the user may experience an operational failure for the default
settings.
"N/A" indicates that the user cannot change the state of the signal.
