15.7.9 Set/Reset function block SRMEMORYQT
The Set-reset function (SRMEMORYQT) is a flip-flop with memory that can set or reset an output
from two inputs respectively. Each SRMEMORYQT function block has two outputs, where one is
inverted. The memory setting controls if, after a power interruption, the flip-flop resets or returns
to the state it had before the power interruption. The SET input has priority.
SRMEMORYQT can propagate the quality, the value and the time stamps of the signals via
IEC61850.
