The figure below illustrates the external wiring of the 2-array matrix input loop constructed by X40
~ X47 and Y40 ~ Y41. The 16 switches correspond to the internal relays M10 ~ M17, M20 ~ M27.
The wiring should be applied with MTR instruction.

When output Y40 is ON, only inputs in the first array are read. The results are stored in auxiliary
relays M10~M17. After Y40 goes OFF, Y41 turns ON. This time only inputs in the second array are
read. The results are stored in M20~M27.
