Operands:
S
1
: Start device in the data table S
2
: No. of counter D: Start No. of the devices for the comparison results
n : Number of data for comparison
Explanations:
1. When S
1
designates KnX, KnY, KnM and KnS, the 16-bit instruction has to designate K4 and 32-bit instruction
has to designate K8.
2. Range of n : 1 ~ 64
3. See the specifications of each model for their range of use.
4. ABSD instruction is for the absolute control of the multiple output pulses generated by the present value in the
counter.
5. S
2
of DABSD instruction can designate high speed counters. However, when the present value in the high
speed counter is compared with the target value, the result cannot output immediately owing to the scan time. If
an immediate output is required, please use DHSZ instruction that is exclusively for high speed counters.
Program Example:
1. Before the execution of ABSD instruction, use MOV instruction to write all the set values into D100 ~ D107 in
advance. The even-number D is for lower bound value and the odd-number D is for upper bound value.
2. When X10 = On, the present value in counter C10 will be compared with the four groups of lower and upper
bound values in D100 ~ D107. The comprison results will be stored in M10 ~ M13.
3. When X10 = Off, the original On/Off status of M10 ~ M13 will be remained.

4. M10~ M13 will be On when the present value in C10 ≦ upper bound value or ≧ lower bound value.
Lower bound value Upper bound value Present value in C10 Output
D100 = 40 D101 = 100 40 ≦ C10 ≦ 100 M10 = On
D102 = 120 D103 = 210 120 ≦ C10 ≦ 210 M11 = On
