Similar logic is applied. See Figure 4.3-12 by replacing "HHD" with "VAR".
Operate condition for HHD&VAR resetting
(iii)
Figure 4.3-13 shows the operate condition logic for HHD&VAR resetting. It examines an
operate-condition using "Command Blocking" signal
Command blocking*1 (defined as "CBK")
Control hierarchy (e.g. 43RL) (PLC connection point #3)*3

as the state of "Command Blocking" in the SOFTSW function.
Note: The criteria "unmatched conditions" is determined when the "Test-bit status" in a
2
command is not identical to the "IED test status".
Note: The user must program the PLC logic "Control hierarchy condition". The Control
3
hierarchy condition provided by the user-programmed PLC logic may be 43R/L;
the user can connect it with PLC connection point "PWRQ_CTRL_RIGHT" of
Figure 4.3-13.
