at the monitoring point “TPOS01_CC_SS”, when the TPOS01 function determines that the
“Local-Cancel” signal is true.
(iii) Cancel condition logic
Figure 4.9-25 shows the cancel condition logic. As the criteria “Unmatched condition detected”
is connected normally for the cancel condition logic, set Fixedlogic for the scheme switch
[TPOS01-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”, like in Figure 4.9-20.

Note: With the exception of the above ‘cancel’ logic, there is an operate-condition logic
within the TPOS01 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
using the connection point “User Configurable condition”:
➢ Connect the user-customized logic, with the “TPOS01IN_TMP_40”, which is listed
in Table 4.9-12.
➢ Set scheme switch [TPOS01-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 the 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.
