composed of X0.0~X0.7 and Y0.0~Y0.7. The corresponding internal relays of the 16 switches
are M10~M17 and M20~M27.

3. The eight input devices starting from X0.0 are connected to the two output devices starting
from Y0.0 to form the two rows of switches. The states of the two rows of switches are read in
the matrix scan, and stored in the devices starting from M10 specified by D
of the first row of switches are stored in M10~M17, and the states of the second row of
switches are stored in M20~M27.
Additional remark:

2. If n is less than 2, or if n is larger than 8, the instruction is not executed, SM0 is ON, and the
error code in SR0 is 16#200B.
3. If users declare the operand S in ISPSoft, the data type will be ARRAY [8] of BOOL.
