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 IEC 61850.
