For example, store the 32-bit rising point data to devices having an even device number, and store the 32-bit
falling data to devices having an odd device number.

Cautions
1. Specifying a high-speed counter (C235 to C255)
In DABSD instruction, a high seed counter can be specified as
In this case, however, the output pattern contains response delay caused by the scan cycle with regard to the current
value of a counter.
When high responsitivity is required in FX
the HSZ instruction, or use the HSCT instruction.
2. When specifying digits of a bit device as
1)
Device number
Specify a multiple of 16 (0, 16, 32, 64 ...).
2)
Number of digits
- In ABSD instruction (16-bit operation): Only K4 is available.
- In DABSD instruction (32-bit operation): Only K8 is available.
3. Other cautions
• The value "n" determines the number of target outputs (1 ≤ n ≤ 64).
• Even if the command input is set to OFF, the ON/OFF status of outputs does not change.
