• INVERTERQT function block that inverts the input signal and propagates
timestamp and quality of input signal.
• PULSETIMERQT Pulse timer function block can be used, for example, for pulse
extensions or limiting of operation of outputs. The function also propagates
timestamp and quality of input signal.
• XORQT XOR function block. The function also propagates timestamp and quality
of input signals. Each block has two outputs where one is inverted.
• 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
timestamp and quality of input signal.
• ANDQT AND function block. The function also propagates timestamp and quality
of input signals. Each block has four inputs and two outputs where one is inverted.
• 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 timestamp and
quality of 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 timestamp and
quality of input signal.
• 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 timestamp of an output
will be set to the latest timestamp of INPUT and VALID inputs.
• INDCOMBSPQT combines single input signals to group signal. Single position
input is copied to value part of SP_OUT output. TIME input is copied to time part of
SP_OUT output. Quality input bits are copied to the corresponding quality part of
SP_OUT output.
• INDEXTSPQT extracts individual signals from a group signal input. Value part of
single position input is copied to SI_OUT output. Time part of single position input
