Function and operation explanation
1. 16-bit operation(HKY)
The numerical value scanned by the signals of the input for connecting 16 keys (0 to F) (device designated in
) and the row output (device designated in ) and by pressing keys 0 to 9 is stored in the device
designated in , and the key sense output is issued to the device designated in .
When any one of keys A to F is pressed, the key pushing information corresponding to the key (device
designated in ) is turned ON, and the key sense output (device designated in ) is issued.
1) Numerical value input by keys 0 to 9
If more than 9,999, the value overflows from the higher digits.
- The entered numerical value is stored in as BIN (binary) value.
- The key sense output +7 is turned ON by pressing any one of keys 0 to 9.
2) Key pushing information of keys A to F
- To turn ON 6 points from corresponding to any one of keys A to F.
- The key sense output +6 is turned ON by pressing any one of keys A to F.
2. 32-bit operation(DHKY)
The numerical value scanned by the signals of the input for connecting 16 keys (0 to F) (device designated in
) and the row output (device designated in ) and by pressing keys 0 to 9 is stored in the device
designated in , and the key sense output is issued to the device designated in .
When any one of keys A to F is pressed, the key pushing information corresponding to the key (device
designated in ) is turned ON, and the key sense output (device designated in ) is issued.
1) Numerical value input by keys 0 to 9
- If more than 99,999,999, the value overflows from the higher digits.
- The entered numerical value is stored in ( +1, ) as BIN (binary) value.
- The key sense output +7 is turned ON by pressing any one of keys 0 to 9.
2) Key pushing information of keys A to F
As for the key pushing information, refer to the previous page on 16-bit operation (HKY).
