2. Set scheme switch [SPOS01-LGEXFFCT] to Fixedlogic.
Replacing the original logic
If the user wishes to replace the operate condition logic completely, it can be achieved using
PLC connection point “User configurable condition”:
1. Connect the user-customized logic using “SPOS01IN_TMP_41”, listed as PLC#2 in
Table 4.1-17.
2. Set scheme switch [SPOS01-LGEXFFCT] to PLC.
Note: The user must program PLC logic “Control hierarchy condition”. The Control
hierarchy condition to be provided with the user-programmed PLC logic may be
43R/L; it may be connected using PLC connection point “SPOS01IN_TMP_28” in
Figure 4.1-29.
Note: The output of the operate condition logic is provided separately for On-execution
and for Off-execution. To see the outputs, refer to Table 4.1-18.

Note: “Command blocking” disables any operation except for itself; “Command
Blocking” is implemented as “CBK”in software switch controller (SOFTSW).The
IEC 61850 standard defines communication blocking as “CmdBlk”. For more
