17.8.2 Functionality
The rated system frequency and phasor rotation are set under Main menu/
Configuration/ Power system/ Primary values/PRIMVAL in the local HMI and
PCM600 parameter setting tree.

17.9 Signal matrix for analog inputs SMAI
17.9.1 Functionality
Signal matrix for analog inputs function (SMAI), also known as the preprocessor
function, processes the analog signals connected to it and gives information about all
aspects of the analog signals connected, like the RMS value, phase angle, frequency,
harmonic content, sequence components and so on. This information is then used by
the respective functions in ACT (for example protection, measurement or
monitoring).
The SMAI function is used within PCM600 in direct relation with the Signal Matrix
tool or the Application Configuration tool.
The SMAI function blocks for the 650 series of products are possible
to set for two cycle times either 5 or 20ms. The function blocks
connected to a SMAI function block shall always have the same cycle
time as the SMAI block.
