3.2 Designating Data
When destination (D) data is a word device, the word device for the destination becomes 0 following the bit designated by
digit designation at the source.
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.
• When digit designation processing is conducted, a random value can be used for the bit device initial device
number.
• Digit designation cannot be made for the direct access I/O (DX, DY).
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).
