Use Iterated User Data Types

jawojtek

Hi.



Need to use numbers in variable names and use them (numbers) in loops. To iterate them.

I have a data type with 10 elements of two-dimensional arrays.
I want to use them to store data from SICK IVC-2D camera  - read/write product's positions.



I decrease no. of elements to 3 to simplify case:





RECORD poseCol

  pose p0, pose p1, pose p2

ENDRECORD



VAR poseCol poseCollection_0;

VAR poseCol poseCollection_1;

VAR poseCol poseCollection_2;





I cannot use array in RECORD statement - so I have to use such a structure.



I need to read/write all elements from all poseCol variables.

I tried to use '%' but I think it works only for PROC:



FOR i FROM 0 TO 2 DO
  %"poseCollection_0.p"+NumToStr(i,0)% := ....;
ENDFOR




Does anybody know solution for such a task?


Furthermore because I cannot use arrays in RECORD statement I cannot use DIM function to make my code more flexible.

Have you tried the SetDataVal command, i have used this for a similar situation before. It allows you to build a string and use that to specify the variable name.

No, I have not... and I think I should

GetDataVal and SetDataVal should solve most of the problems.

 

Thanks!
