instructions. When receiving digital switch information in binary-coded decimal (BCD) format into a CPU module, use the
BIN(P) instructions (for converting BCD data into binary data). Furthermore, to output data to seven-segment display unit
handling binary-coded decimal (BCD) data, use the BCD(P) instructions (for converting binary data into BCD data).
