Explanation:
1. The ten external inputs starting from the input specified by S represents 0~9 in the decimal
system. They are connected to ten keys. Users can enter a four-digit decimal value or an
eight-digit decimal value by pressing the keys in order. The decimal value is stored in D
the output signals are stored in D
2. The operand S occupies ten bits.
3. The operand D occupies eleven bits. Please do not change the states of the bits during the
2
execution of the instruction.
4. When the conditional contact is not enabled, the eleven bits starting from the bit specified by
D is OFF.

5. When the on-line editing is used, please reset the conditional contact to initialize the
instruction.
Example:
1. The ten external inputs starting from X0.0 is connected to ten keys which represent 0~9 in the
decimal system. When M0 is ON, the instruction is executed. The value that users enter is
stored as a binary value in D0, and the output signals are stored in M10~M19.
