IN PROGRESS
My early posts were often quite brief, and some of the explored techniques were never returned to despite my intentions.
A shawl tale was written in 2009.
The designs explored in this post can be found in the Passap Duomatic baby book. 
A closer look: 
My attempt at a hand technique at that time, 
and the declaration of a planned challenge, “creating a downloadable stitch pattern that will automatically select appropriate needles and duplicate this texture.” It only took 16 years!
The pattern chart: 
on the Japanese machines, the beds are reversed. 
The back bed = ribber in our case, is set to knit every row.
Locks is the Passapese for carriages.
Many patterns can be achieved by lock settings and arrow keys without added programming. In Brother machines, a small cousin of the function is found in the use of lili buttons.
When an arrow key is pressed, it tells the Passap machine to engage the pushers. Depending on the direction of the movement of the locks, the pushers will be lifted or pushed down. Their initial position is set up manually.
The left arrow key changes pusher selection when the locks move to the left.
The right arrow key changes pusher selection when the locks move to the right. Use of both arrow keys simultaneously will change the pusher selection every row.
With the Zero key, no arrow selected, the pushers do not change their position on that pass, repeating the selection.
Pushers preselect for the next pass, as happens with needle preselection in Brother.
AX is the tuck setting for Passap, pushers selected up knit, selected down tuck.
When setting up these patterns, it is best to have a needle on the ribber on each side, not observing the usual “needle rule” for rib knits.
When working on both beds, the default illustrations have a space > dot between needles in work to permit the illustration of needles between them on the opposite bed, so the chart is not for an every other needle design. In this instance, stitches > needles in work occur in pairs on the top bed.
Programming the repeat: the first pass will knit or tuck alternate pairs of stitches.
The needle selection then stays fixed for 3 rows and reverts to the first selection, a 4-row design. Stitches will be tucked side by side, breaking another common rule.
The ribber needles in this case are extra, not transferred down to the ribber from the knit bed as in some of the fabrics recently explored in other posts.
They are brought into work between pairs of knit stitches on the top bed, represented by the red lines in this chart.
Because of their location, the ribber should be set for half pitch.
With use the beds can shift, for tips on ribber alignment please see post:
A bit on ribbers: Japanese KMs, alignment, and symbols 1.
The stitches on the ribber are outlined with cyan, the triple tuck loops as those needles are brought forward on the knit bed for knitting with white. 
The proof of concept, programmed on 46X24: 
The darker color was thicker, knit well, but since this was a test, seeing stitch formation while checking for accuracy mattered. Testing the pattern on the knit bed first determines any problems with the design before the ribber is brought into work, limiting visibility as the knit progressed.
The same repeat, with stitches transferred down to the ribber, leaving empty needles on the top bed, knit on every other needle with 2/8 wool, produced an interesting texture, but quite a narrow knit, 3.5 inches wide. 
Racking on EON rib: some considerations.
A different design, with the repeat cut in half widthwise for a more traditional tuck stitch configuration,
also with stitches from the ribber between stitches on the main bed
a knot in the yarn knit right through and was missed, easy to do when working double bed if the yarn travels with no hesitation
This design uses a simple racking pattern, easy to execute in thin yarns, but not as impactful. 
In Brother the ribber performs the racking movements.
Both beds are set for plain knit.
The needle set up is on half pitch.
Cast-on for the test swatch was with the racking position starting on 8, with the plan to rack to 10, knit 2 rows, rack back to 8, knit 2 rows, and repeat, performing all position changes with the carriages on the left.
The yarn used is a 2/18 wool/silk blend that resisted the technique regardless of tension and weight adjustments, and began breaking, but there is enough knit to visualize the result. 
Pattern 2053 
is for reversible checkerboards that use tuck settings on both beds,
The strippers in the Passap system help push down on loops and knit stitches, anchoring them in a way simply not possible in Brother models. Even if a choice were to be made to push down between the beds with a hacked tool, the Brother needle preselection renders that impractical.
The concept behind the Duomatic version is then switched to automated patterning with the tuck setting on the main bed, and the ribber set to knit every row.
The two rows with one arrow key result in the repeat shifting locations by repeating the same selection, as seen in this chart
The 8X40 design was knit on 48 stitches, these knits are quite wide, loose bind off are required when the pieces are completed.
Each sample knit measures 11.5 inches in width.
Where 4 side by side needles are tucking for four rows, the stitches on the ribber may have a tendency to jump off, resulting in loops not being anchored, so those areas require special attention. The proof of concept for the above repeat in one color and then with color changes every 2 rows
More variations including racked ones are explored in Fisherman_ English tuck stitch rib 1_ checks patterns_ Brother, Passap.
