dont worry english is fine for us.

redimension of arrays at runtime is forbidden under iec61131 standard
it is not available and possible on sps systems under the iec61131 standard

Thanks for the answer

What I am trying to write control system that has what term as collections of controls, In my case there would be collection of bins that would have collection of gates and so on (I am software developer so I am used being able to do this). These collections will be constant at particular site but change at the next implementation. So what I want to know how you would go about this. The problem is that a bin may variable number of gates. I hope this makes senses

Cheers

what can can do is create structures and arrays of structures
the array size you can define at compilation time with a constant

like:
var
   dummy : array[0..size] of bins;
end_var
var constant
   size : int := 6;
end_var
