Y0, Y10, Y20 ... final output device number (Only "0" is allowed
in the least significant digit of device numbers.))
(d2) Head bit device (Y, M or S) number of ON output destination
Y0, Y10, Y20 ... final Y number, M0, M10, M20 ... final M number
or S0,S10, S20 ... final S number (Only "0" is allowed in the least
significant digit of device numbers.)

Processing details
• An input signal of 8 points x "n" columns is controlled in the time division method using 8 inputs specified in (s) and
transistor outputs specified in (d1). Each column is read in turn, and then output to devices specified in (d2).
• For each output, the I/O processing is executed immediately in turn in interrupt at every 10 ms or 20 ms.
