• 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 is copied to TIME output. Quality bits in common part and indication part
of inputs signal is copied to the corresponding quality output.
