input is copied to TIME output. The quality bits in the common part and the indication
part of inputs signal are copied to the corresponding quality output.
• INVALIDQT function which sets quality invalid of outputs according to a "valid"
input. Inputs are copied to outputs. If input VALID is 0, or if its quality invalid bit is
set, all outputs invalid quality bit will be set to invalid. The time stamp of an output
will be set to the latest time stamp of INPUT and VALID inputs.
• INVERTERQT function block that inverts the input signal and propagates the time
stamp and the quality of the input signal.
• ORQT OR function block that also propagates the time stamp and the quality of the
input signals. Each block has six inputs and two outputs where one is inverted.
• PULSETIMERQT Pulse timer function block can be used, for example, for pulse
extensions or limiting of operation of outputs. The function also propagates the time
stamp and the quality of the input signal.
• RSMEMORYQT function block is a flip-flop that can reset or set an output from
two inputs respectively. Each block has two outputs where one is inverted. The
memory setting controls if the block after a power interruption should return to the
state before the interruption, or be reset. The function also propagates the time stamp
and the quality of the input signal.
• SRMEMORYQT function block is a flip-flop that can set or reset an output from
two inputs respectively. Each block has two outputs where one is inverted. The
memory setting controls if the block after a power interruption should return to the
state before the interruption, or be reset. The function also propagates the time stamp
and the quality of the input signal.
• TIMERSETQT function has pick-up and drop-out delayed outputs related to the
input signal. The timer has a settable time delay. The function also propagates the
time stamp and the quality of the input signal.
• XORQT XOR function block. The function also propagates the time stamp and the
quality of the input signals. Each block has two outputs where one is inverted.
