Operands:
S : Start device for key input D
1
: Device for storing keyed-in value D
2
: Key output signal
Explanations:
1. S will occupy 10 consecutive points; D
2
will occupy 11 consecutive points.
2. See the specifications of each model for their range of use.
3. For SA series MPU, S and D
2
do not support E, F index register modification.
4. This instruction designates 10 external input points (representing decimal numbers 0 ~ 9) starting from S. The 10
points are respectively connected to 10 keys. By pressing the keys, you can enter a 4-digit decimal figure 0 ~
9,999 (16-bit instruction) or a 8-digit figure 0 ~ 99,999,999 (32-bit instruction) and store the figure in D
1
. D
2
is
used for storing key status.
5. There is no limitation on the times of using this instruction. However, only one instruction can be executed at a
time.
Program Example:
1. Connect the 10 input points starting from X0 to the 10 keys (0 ~ 9). When X20 = On, the instruction will be
executed and the keyed-in values will be stored in D0 in bin form. The key status will be stored in M10 ~ M19.
