Using the Instruction
If the input word for connecting the 10-key keypad is specified for IW, then
operation will proceed as shown below when the program is executed.
Note 1. While one key is being pressed, input from other keys will not be accepted.
2. If more than eight digits are input, digits will be deleted beginning with the
leftmost digit.
3. Input bits not used here can be used as ordinary input bits.
Application Example In this example, a program for inputting numbers from the 10-key is shown.
Assume that the 10-key is connected to IR 000.
The 10-key information input to IR 000 using TKY(18) 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.
