Dynamic text input [message #1864017]

Hello,

is it possible to make the input of a FB dynamic?

For example:

I have an input called "TEXT1" from type REAL. For example "45" .

In structured text I managed to sort a number to get an array [2,1,3].
Now I want to call the input by using the sorted array and use it in my code like
23 + "TEXT+arr[1] " = 23+ 45 = 68

I hope you understand what I want to do.

Best regards
Wolfgang

so you want to convert a number from an array (UINT#1) into a string and then append to another string ("TEXT")?

if so, then i would use "F_UINT_TO_WSTRING" from "iec61131-3" module of FORTE to convert the UINT number into Wstring and then "APPEND_STRING_2" from "utils" module of FORTE to join both strings into one.

I'm sorry but there is no way in IEC 61131-3 or IEC 61499 to address in our outputs by index. The only solution that I know would be to have the input as array.
