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.
