Figure 4.3-10 Select condition logic for HHD&VAR resetting
Note: If tripping (GEN.TRIP in Table 4.3-5) is executed in the IED, any control
1
operation is blocked upon the trip operation. Tripping can be introduced by the
protection function if the IED has protection functions.
Note: Criteria "unmatched conditions" are decided when "Test-bit status" in command is
2
not identical to "IED test status".
Note: The user shall 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 at PLC connection point "PWRQ_HHD_RSTREQ" of Table
4.3-5.
