When executing dual output (use dual coil), the after one is act in priority.
As shown in the left map, please
consider the case of using the same coil
Y0 at many positions:
E.g.X0=ON, X1=OFF
The first Y0: X0 is ON, its image area is
ON, output Y1 is also ON.
The second Y0: as input X1 is OFF, the
image area is OFF.
So, the actual output is: Y0=OFF,
Y1= ON.
