Output signal to BO
The DPOS01 function, illustrated in Figure 4.8-17, is able to issue a “Success of cancel” signal
at the monitoring point “DPOS01_CC_SS”, when the DPOS01 function determines that the
signal “Local-Cancel” is true.
(iii) Cancel condition logic
Figure 4.8-18 shows the cancel condition logic. As the criteria, “Unmatched condition detected”
is connected normally for the cancel logic, set Fixedlogic for the scheme switch [DPOS01-
LGCNFFCT].

Note: The criteria “unmatched conditions” are determined when the “Test-bit status” in
the ‘cancel’ command is not identical to the “IED test status” as in Figure 4.8-13.

Note: With the exception of the above ‘cancel-condition’ logic, there is an operate-
condition logic within the DPOS01 function; the operate-condition logic will
always checks conditions. That is, the user is required to set either the “operate-
condition” or the “cancel-condition” logic.
If the original logic does not meet with the requirement of the user, it can be relpced using
the connection point “User configurable condition”.
1. Connect the user-customized logic with the “DPOS01IN_TMP_44”, which is listed
in Table 4.8-11.
2. Set scheme switch [DPOS01-LGCNFFCT] to PLC.
