3.2 Designating Data
3.2.2 Using word (16 bits) data
(c) 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.
Fig 3.2 Ladder Example and Processing Conducted
(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.

(2) Using word devices
Word devices are designated in 1-point (16 bits) units.
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).
