4.4 Method for Specifying Data
4.4.3 Double word (32 bits) data
4-27

PROGRAM CONFIGURATION
(b) The following table shows the numeric values that can be used as source data when
digits are specified at the source .
Table 4.4.3-1 List of digit specification and numeric values that can be used
(c) When the destination is a word device
For the word device at the destination side, 0s are stored as the status of bit devices
which follow the digit-specified bit devices at the source side. (Data_s:K1X0,
Data_d:D0)
Figure 4.4.3-2 Ladder example and processing details
(d) When digits are specified at the destination , the points by the specified digit are the
target of destination. (Data_d1:K5M0, Data_d2:K5M10, Data_s:D0)
The status of bit devices which follow the digit-specified bit devices is not changed.
