In this example, a program for inputting numbers from the 10-key is shown. As-
sume that the 10-key is connected to IR 000.
The 10-key information input to IR 000 using TKY(––) is converted to BCD and
stored in DM 1000 and DM 1001. Key information is stored in DM 1002.
IR 00015 is used as an "ENTER key", and when IR 00015 turns ON, the data
stored in DM 1000 and DM 1001 will be transferred to DM 0000 and DM 0001.
