Hallo MSB!
you have to wire each input to a marker of the same MB (or MW, if you need)
e.g. I1 to M9, I2 to M10...
Then you select "roll masks" in the last card of "Visualisation". I don'k know the exact englisch designation. It should be something like "Mask control"
Then you select your specified MB and select a Mask for every bit.
