S7 Indirect Addressing of Array

[douyi]

Hi guys,

Is it possible to decalre a variable then use it on Arry such as:

In DB100, I decalred an array as
Array1 is Array[1..100] of UDT1

Then, in the FC I want to pass by an array index number and then use like

Array1[Index_Number].xxx

I tried directly and AR1, seems doesn't work. If this way doesn't work, I have to calculate start address of each element of the array and it's more complex.

Is there any better idea on that?

Thanks a lot.

see my thread. I had the same problem.

Thanks Martin, I checked your topic.

Is that means I have to do it in SCL or I can only use numbers in array?

Yes, it means exacty this. With SCL I am not sure because I don't know it, but in STL it's impossible to do it indirectly.
