Operands:

S: Matrix source device n: Array length D: Pointer (Pr), for storing the value of target location

Explanations:

1. Range

of

n: K1 ~ K256

2.

S designates KnX, KnY, KnM and KnS; D designates KnY, KnM and KnS.

3.

SA/SX/SC can designate n = 4. EH/EH2/SV can designate n

4

≦ .

4.

See the specifications of each model for their range of use.

5.

Flags: M1089 ~ M1096. See remarks for more details.

6.

When this instruction is executed, if first determines if the matrix pointer clear flag (M1094) is “On”, If it is “On”,

pointer D is cleared as 0. The instruction then writes the value in the matrix displacement/input complement

flag (M1096) into the location starting from the 0

th

bit of S. Whenever finishing writing 1 bit, the instruction

determines whether the matrix pointer increasing flag (M1093) is “On”. If it is “On”, the value of pointer D will

plus 1. When the writing is processed to the last bit, the matrix search end flag (M1089) will turn “On” and

pointer D records the No. of written bits. If D exceeds its range, M1092 will be On.

7.

The Pointer (Pr) of the matrix is designated by the user in the instruction. The vaild range of Pr is 0 ~ 16n -1,

corresponding to b

0

~ b

16n-1

in the matrix. If the Pr value exceeds its range, M1092 will be On and the instruction

will not be executed.

Program Example:

1.

When X0 goes from Off to On, M1094 will be set to “0” and M1093 to “1”. Therefore, the Pr will plus 1 after

every writing.

2.

Set the Pr value D20 = 45 and M1096 = 1. When X0 goes from Off to On for 1 time, we can obtain the execution

results: D20 = 45, M1096 = 1, M1089 = 0.
