This instruction uses a comparison table which is headed by the and continuously occupies × 3 registers,
then takes the present value of the designated Software High Speed Counter to compare to that table,
furthermore the comparison result presents through the headed continuously components. Both the
values comparison and result outputting at this instruction are operated by the interruption of system.

Output
Appointer
Table Counter
When X20 = “ON”, this instruction starts operation. The present value of C235 SHSC assigned by will
st
compare with the content value of the 1 data set (D1, D0) in the comparison table. If the input makes those
st
values equal, the content value of the 1 output appointer (D2) in the comparison table will be instantly output
through the Y4~Y6 (assigned by and ), also it increases the value in the table counter D9162 by 1
nd
(become 1 from 0). After that, the present value of C235 will compare with the content value of the 2 data set
nd
(D4, D3) in the table. When the values are equal, the content value of the 2 output appointer (D5) in the table will
be instantly output through the Y4~Y6, also it increases the value in the table counter D9162 by 1 (become 2 from
1). The comparison action is continuous, until the value of the last data set in the table is equal to the present
value of C235. That causes the operation completion ag M9162 for one Scan Time and the D9162 will be reset to
st
0, furthermore the comparison operation should start over again from the 1 data set.
When the X20 turns from “ON” to “OFF”, this instruction stops and the content value of D9162 will be reset to 0 but
the result status which has output previously will still remain.
This instruction is a 32-bit instruction. Therefore, be sure to input DHSCT in the program.
This instruction can only be used once in the program.
