When trying to use the Visualization ToolBox, no objects appear and the following error appears. Could you tell me what this error could be? The element of type 'VisuFbElemImage' could not be updated. Reason: Index was outside the bounds of the array. Can anyone tell me what this error is?

Still a problem in 3.5.19.20 which is absolutely ridiculous.

Thanks Tim! This was exactly the functionality we were looking for. We are already using implicit checks to check for divide by 0 errors, we will add implicit checking for array bounds.

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.

Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Hello, I was wondering if there was further documentation on the SharedMemory library in CodeSys outside of the code example provided, or maybe a way to access the source code of the shared memory implementation. Thank you in advance for any advice. - Viktor

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
