It seemed as if the MC1 and MC3 suspension are receiving constants from LSC and ASCIMC, i.e. L=1, P=3 and Y=5, no matter what we did for IMC WFS (first screenshot).

Eventually we found that the model is old and corresponding inter-computer communication parts were just padded with 1, 3 and 5 in the model (second screenshot).

Without updating the model WFS wouldn't work.
