KEY
(2) Numerical input to input (X) designated by
+7 and is input as the ASCII code corresponding to the numbers.
S
ASCII code which can be input is from 30
(3) After ASCII code is input to
designated numbers internally.
The strobe signal should be held at its ON or OFF status for more than one scan of the
sequence program.
If this time is less than 1 scan, there will be cases when the data is correctly incorporated.

(4) Be sure to keep the execution command (condition contact for the KEY instruction) ON until
the specified number of digits has been input.
The KEY instruction cannot be executed if the execution command turns OFF.
(5) The digits for the numbers actually fetched to
