15.7 Configurable logic blocks Q/T
GUID-0CA6511A-E8BD-416E-9B59-5C6BD98C60B7 v4
The configurable logic blocks QT propagate the time stamp and the quality of the input signals
(have suffix QT at the end of their function name). The propagation of information is part of the
IEC 61850 capabilities.
The function blocks assist the user to adapt the IEDs' configuration to the specific application
needs. The list below shows a summary of the function blocks and their features.
• ANDQT AND function block. The function also propagates the time stamp and the quality of
input signals. Each block has four inputs and two outputs where one is inverted.
• 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. The value part of single
position input is copied to SI_OUT output. The time part of single position 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
