Hello

Im new to step 7 and STL, i´m trying to store data in an array for historical use in a batch.

Have an array[0..144] only need 144 but the problem with my code is that it wont start att array[0] it starts at array[1].

I have noticed the problem thus when counter gets to 1 "first produkt on scale" its will be 1*2 and thats 2 thus array[1]. But tried to subtract 2 in the code but will not work for me.

Anyone has a solution for me.

   OPN   "Array Vikt"

      L     P#DBX 0.0 // pointer start at bit 0.0 im my array ?

      LAR1  

      T     #Num_1 // temp_pointer ? is that correct

      L     #Num // its a counter that goes from 0 to 144

      L     2

      *I    

      SLD   3

      +AR1  

      L     #Num_1

      L     #Vikt // the weight of the product

      T     DBW [AR1,P#0.0]

It's not really clear to me what you wanna achieve. But maybe I got it right...

      LAR1   P#DBX 0.0

      L     #Num // its a counter that goes from 0 to 144

      SLD   4

      +AR1  

      L     #Vikt // the weight of the product

      OPN   "Array Vikt"

      T     DBW [AR1,P#0.0]

What i want to do is whenever #Num counts up +1 the weight of the new product shall be stored in the array[i] i=i+1. But i had a problem that the first produkt was stored in array[1] rather than array[0].

But i did solve it this morning. Now its works fine.

Thnx for all the help.

OPN #DB

L P#DBX 0.0

LAR1

T #tempPointer

L #Num

L 2

*I

+ -2

SLD 3

+AR1

L #tempPointer

L #weight

T DBW [AR1, P#0.0]
