15.1 FNC 70 – TKY / Ten Key Input
Outline
This instruction sets data to timers and counters through inputs of the ten keys from "0" to "9".
1. Instruction format
2. Set data
3. Applicable devices
S: "D.b" cannot be indexed with index registers (V and Z).
Explanation of function and operation
1. 16-bit operation (TKY)
stores a numeric value input from to +9 connected to the ten keys. Output informations for key
pressing and key sensing are output to to +10.
1) Input numeric value
- When an input value is larger than "9999", it overflows from the most significant digit.
- An input numeric value is stored in the binary format.
- When the ten keys are pressed in the order "[1] → [2] → [3] → [4]" in the figure shown on the next page, "2130"
is stored in .
Operand Type Description Data Type
Head bit device number from which one of the ten keys is input [10 devices are occupied] Bit
Word device number storing the data 16- or 32-bit binary
Head bit device number storing the key pressing information [11 devices are occupied] Bit
