1 OVERVIEW
1.2 Data Specification Method

■
Specifying a bit device with digit specification in the source (s)
When a bit device with digit specification is specified in the source of an instruction, 0 is stored in the bits, which follow the bit
for which digit specification is made in the source, in the word device of the destination.
■
Specifying a bit device with digit specification in the destination (d)
When a digit specification is made in the destination of an instruction, the number of points by the digit specification is
applicable in the destination.
The bit devices after the number of points specified by digits remain unchanged.
Handling 32-bit data with word devices/labels
■
Word device
Two points of word device can handle 32-bit data.
Note, however, that one point of the following devices can handle 32-bit data.
• Long timer (LT)
• Long retentive timer (LST)
• Long counter (LC)
• Long index register (LZ)
■
Double word type label
One point of double word device can handle 32-bit data.
Ladder example
Processing
• 32-bit data instruction
Ladder example
Processing
• When the source data is a word device
(1) The data remain the same.
