Post by apurv on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
I have a Array of constant size defined like this Var Constant MAX_SIZE :UINT := 10; End_var VAR array : ARRAY[0..MAX_SIZE] OF INT; END_VAR Now I want to pass this array to a function by reference, Function fun : INT VAR_IN_OUT CONSTANT MAX_SIZE : UINT; END_VAR VAR_INPUT array : REFERENCE TO ARRAY[0..MAX_SIZE] OF INT; END_VAR but when I run this it gives strange Errors Error : Cannot Convert type 'ARRAY [0..MAX_SIZE] OF INT' to type 'ARRAY[0..MAX_SIZE] OF INT'

Post by john-robinson on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.
