1) Write the following data to [
,
+1] to [
+4n-2,
+4n-1] in advance using a transfer instruction:
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.
falling data to devices having an odd device number.
When the command input is set to ON, "n" points starting from
change as shown below.
Each rising point/falling point can be changed respectively by overwriting the data in [
+1,
] to
[
+4n-1, +4n-2].
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.

PLCs, use the table high speed comparison function offered by 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.
- 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.
