(iii) Cancel condition logic
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
[SPOS01_LGCNFFC].

Note: The Criteria “unmatched conditions” are determined when the “Test-bit status” in
the cancel command is not identical to the “IED test status”, like in Figure 4.1-13.

Note: With the exception of the above ‘cancel’ condition logic, there is an operate-
condition logic within the SPOS01 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 requirements of the user, it can be replaced
with another logic using the connection point “User Configurable condition”:
1. Connect the user-customized logic with the “SPOS01IN_TMP_46”.
2. Set scheme switch [SPOS01-LGCNFFCT] to PLC.
(iv) Signal name and number
Note: The user should note the following descriptions shown in the column “M/O” in
each table:
“O” indicates that the signal is provided for optional use.
“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.
