Operation principle

The Signal matrix for binary outputs (SMBO) function , see figure 284, receives
logical signal from the IED configuration, which is transferring to the real
(hardware) outputs, via the Signal Matrix Tool (SMT) or ACT. The inputs in
SMBO are BO1 to BO10 and they, as well as the whole function block, can be tag-
named. The name tags will appear in SMT as information which signals shall be
connected between physical IO and the SMBO.
Signal matrix for analog inputs SMAI
Functionality
Signal matrix for analog inputs (SMAI), also known as the preprocessor function
block, analyses the connected four analog signals (three phases and neutral) and
calculates all relevant information from them like the phasor magnitude, phase
angle, frequency, true RMS value, harmonics, sequence components and so on.
This information is then used by the respective functions connected to this SMAI
block in ACT (for example protection, measurement or monitoring functions).
