(d) In cases where digit designation is made at the destination (D), the number of points designated are used as the
destination. Bit devices below the number of points designated as digits do not change.
Ladder Example
When source (S) data is a numerical value
X10
When source (S) data is a word device
X10
1. When digit designation processing is conducted, a random value can be used for the bit device initial device number.
2. Digit designation cannot be made for the direct access I/O (DX, DY).
(2) Using word devices
A word device designates devices used by the lower 16 bits of data. A 32-bit instruction uses (designation device
number) and (designation device number + 1).
